My body type is Erlenmeyer flask and let me tell you, it is extremely difficult to find clothes that fit when you have size 15 feet, huge cankles, and size 20AAAA boobs. So glad wide leg pants are coming back in because they鈥檙e perfect for my inverted ice cream cone legs 馃槏

u/3repeats 路 39 pointsr/Homebrewing

That isn't a volumetric device, those marks are painted by a machine, not by a chemist that verifies every glassware.

You need these, which are hand calibrated, if accuracy is important. (500mL volumetric for example)

u/Absoludacris1 路 8 pointsr/wine
u/zymurgist69 路 7 pointsr/chemicalreactiongifs

I work in a shop where sheet metal is readily available, and scrap is ok to use for whatever we want.

A 120v muffin fan came into my possession by means I do not remember. I glued a neodymium magnet from a dead hard drive to the fan, and built an enclosure to which I mounted the fan, and a 120v dimmer switch to control the speed of said fan.

I then purchased stir bars, to stir the starter in a 2 liter Erlenmeyer flask.

I bought a dimmer switch at Home Depot, and I get an amazing turbination in my starters.


The result is an inexpensive alternative to commercially available stir plates.

Paid $45.00 for the flask, $7.00 for the switch, maybe $9.00 for the stir bars, but the satisfaction of seeing the thing work, and work well, was so validating and fun to do!

u/storunner13 路 7 pointsr/Homebrewing

While I agree with /u/BaggySpandex that additional surface area for air transfer is a benefit, the best part about Erlenmeyer Flasks and a stir plate is you can boil and cool the wort directly in the Erlenmeyer--no need to sanitize a jar, boil in a pot and then cool and transfer. Constant stirring results in more yeast cells and increased vitality.

2L Erlenmeyer flasks are only $19 on Amazon. If you have access to a spare 8v power supply and an old computer, you can built a stir plate with a computer fan, hard drive magnet.

Amazon has really good customer service, just ask for your money back, and you will get it. I once was sold fake Wusthof by one of their 3rd party shops and was pretty upset seeing how I paid north of $400 for them. They refunded the money right away, gave me a gift card for my troubles, and paid for shipping. It took all of 10 minutes to get my money back.

There are Many different types of products on Amazon; Made and sold by Amazon, fulfilled by Amazon by their Prime service, and sold on Amazon. The last option for example ( http://www.amazon.com/gp/product/B001BLKL4W/ ) is on Amazon but sold and shipped by "Ships from and sold by Scientific Strategies." Amazon tries to control when these 3rd party companies pull fast ones, but it can happen. A lot of times, these companies will get black-listed for doing what they did to you. It sucks you got a shitty product, Amazon's should take care of you, no questions asked.

u/Cythos 路 6 pointsr/Coffee

It's basically these four items, seperator funnel, glass funnel, erlenmeyer flask, and a stand. Although I don't know exactly what stand they're using in this particular setup (whether it was purchased in a set (although it does look awfully familiar)), it's not too difficult to reproduce.

u/SnowHawkMike 路 5 pointsr/vaporents

For those of you whom would like to make one of your own you can purchase the magnetic stirrer hot plate here ($210), and the Pyrex Erlenmeyer Flask here ($15.95)! Total investment cost: $225.95.

Alternatively you can purchase this magnetic stirrer hot plate for significantly less, bringing the total cost down to $175.90.

u/rkelly74 路 5 pointsr/Coffee

So I started with the Yama, but thought it would be a fun project to try to make something from scratch. Had to turn to chem glassware, which is a little pricey but I think looks cool. I used a separatory funnel, Buchner funnel, and Florence flask.

Glassware ended up costing about $83, and I used the ring stand we had in the science lab at school.

u/AlphaAnt 路 5 pointsr/Homebrewing

I got my erlenmeyer flask on Amazon. I strongly encourage the actual Pyrex brand, I have an off-brand 1L flask and bought a Pyrex 2L flask, the quality difference is pretty staggering.

Here's the one I bought.

u/2C-The-7uture 路 5 pointsr/AskDrugNerds

Do some research into the active ingredients to find a solvent they are sufficiently soluble in. Crush your pills as well as you can. I suggest you break them down using something hard and flat at first, then use a bic lighter. Rub the powdered pills with the side of the lighter redundantly to create as much surface area as possible. Use a knife, scalpel, or razor blade to scrape the powder off the surface you were rubbing it on. Chop it up for a couple minutes. Warm your solvent a bit if you need to, then mix the powder into it. Shake and stir it for several minutes. Filter off the undissolved binders using a coffee filter, or if you value your time and medication more than money get a manual vacuum filter. You're going to need filter paper for that too.

If the solvent you used isn't an irritant, measure the volume of
the solution you retrieved from the filter flask. Figure out whether or not your solution is as concentrated or dilute as you want. To dilute it, add solvent. To concentrate it, evaporate or boil off the solvent. Make sure your medication isn't going to degrade at the temperature required to boil off your excess solvent.

If it is an irritant, boil off most of the solvent and evaporate the rest. Scrape up your dried medication and dissolve it in saline. I suggest you use Snoot nasal spray bottles. God speed, OP.

>[E]very chem lab should have a good number of 150-250 mL glass beakers on hand.

  1. After looking up the differences (incl. price) between regular glass and borosilicate glass, when would borosilicate be mandatory?

    >Some large size glass test tubes will come in handy, and those are relatively cheap.

  2. What would be considered "large size?"

    >Depending on what type of reactions you want to do, you may find it good to have petri dishes handy, either glass or plastic (they'd be good for crystallization experiments, certainly).

  3. How many, and of what size, would be good for starting?

    >You should definitely have a few pipettes, either the cheap plastic 3 mL kind, or if you can afford it, nicer glass droppers (Pasteur pipettes are fun to use, albeit fragile and hard to clean).

  4. Are the glass pipettes for strong acids, basis, or organic solvents? Are there any other benefits to glass pipettes?

    >You will definitely need a graduated cylinder, maybe a few, in different sizes, glass or plastic (definitely glass if you're planning on working with any strong acids or bases, or using organic solvents).

  5. What sizes should I be looking for? I'm guessing polypropelyne is the preferred plastic type since that has the most available on Amazon. Is this Set of 7 Polypropylene Cylinders sufficient? What size glass cylinder would be the most common for home experiments with strong acids, bases, or organic solvents?

    >You will find a scale, accurate to at least a tenth of a gram, to be an invaluable tool.

  6. Could you please recommend a specific scale, or at least a type? I'd like to spend as little as possible without getting a piece of junk. Is there anything available for under $100?

    >Some litmus or pH paper will be useful.

  7. Most of these seem to be range limited. I found what appears to be a full range paper or a set of papers that provide full range. Would you recommend either of these?

    >Oh, and a thermometer, of course!

  8. I thought this one was simple until I looked it up. What exactly am I looking for here? Infrared Thermometers seem like a good idea because they don't physically contact the sample, but I'd like some guidance with regard to a trusted brand.

    >If you want to dispense precise quantities of any liquid, a 25 mL burette will be your best friend, though it's certainly not necessary.

    8.a) This one seems relatively straightforward. Finally!

    >a volumetric flask, for making precise stock solutions.

  9. Size? I've tentatively added a 100ml and 500ml to my list. Is Karter Scientific considered good quality?

    >A few Erlenmeyer flasks, for mixing things.

  10. This set of Erlenmeyer flasks seems like a good place to start. Which sizes do you find yourself needing most often?

    >A volumetric pipette, for making equal aliquots.

  11. Wow, these things appear to be quite expensive. What types of home experiments would it be difficult to do without a volumetric pipette? This one will probably wait until the need arises.

    >Oh, and if you just want your lab to be that much more mad sciencey, you could have a distillation flask and a few condensation tubes bubbling in the background. If you want to make a significant investment, you could get a magnetic stirring platform, maybe one with good heating powers. Also great for whisking up an egg, or keeping some batter moving while you make pancakes. Pricey, though.

  12. I'll probably stay away from the distillation flasks and condensation tubes until I stumble upon an experiment that requires them, but the magnetic stirring platform looks like a much cooler way to make coffee in the morning. Is this stirrer from Hanna Instruments any good?


    Thanks a ton for putting together that list!

u/zfriend 路 3 pointsr/succulents

got it from amazon aprox 5 years ago(along with several other larger sizes) here's a pretty good listing for similar items for $16! seriously though.... so useful... everyone should have these around.

u/XtractionServices 路 3 pointsr/CannabisExtracts

Syringe filters seem very impractical. I've used them in an analytical lab and they clog easily. When dealing with a lot of fat/lipids I don't think they would work well.

Vacuum assisted filtration with scientific filter papers work best.
When selecting a pump, you need to consider getting one that can handle solvents or add a coldtrap to extend pump lifetime. Here's a link to a complete set.

If you don't have very much product and are not interested in spending the money, you can try a hand pump. I've never used one but found it through a quick amazon search.

u/Epsilon748 路 3 pointsr/Seattle

You don't actually need a dark room, it's a common misconception. You only need that if you plan to use an enlarger and make your own prints. I don't, but only due to lack of space in my apartment - I scan them in and order prints at Costco or Bartells like any normal digital scan.

If you get one of the Paterson Reel tanks like I have in that photo, you just need a changing bag. Put your 1-2 rolls of film, a bottle opener, a pair of scissors, and all the tank pieces in the bag. Seal it up, pop open the film canister with the bottle opener, then spool the film onto the reels. Put both reels back in the tank and seal it up. Everything else can be done in daylight. (you can skip the bag and do this in a pitch black room like your bathroom or a closet if you want. I prefer the bag- I can sit on the couch and watch TV while I spool rolls).

Then you're just dumping in chemicals on a timed schedule and then unspooling and hanging them to dry when complete. B&W is roughly 13 minutes a batch at diluted 1+1, or 6 minutes at stock (full strength) solution. Stock just uses it up twice as fast, but saves time.

B&W = developer (12-15 minutes for most films at 1+1 - check the massive dev chart -> stop bath (1 minute) -> fixer (1 minute) -> rinse (2-3 minutes) -> hang to dry (2ish hours or until totally dry).

Color = developer (6ish minutes) -> blix (2-3 minutes) -> rinse (2-3 minutes) -> stabilizer (1 minute) -> hang to dry (2ish hours).

I'm pulling those numbers from memory, but the unicolor kit has a good guide with it.

Stuff you need

u/scoopyloo 路 3 pointsr/DIY_eJuice

I mix mine in flasks, hot water bathe them in a mini crock pot for a few minutes, then give them a few gentle shakes. I've also got a tiny funnel to pour the liquid into bottles.

Here's the funnel I use: http://wizardlabs.us/index.php?route=product/product&path=71_76&product_id=233

These are the flasks I use: http://www.amazon.com/Glass-Erlenmeyer-Flask-Set-Scientific/dp/B008VIHFSI/ref=sr_1_1?ie=UTF8&qid=1413214288&sr=8-1&keywords=erlenmeyer+flask

Well its pretty simple, finding the materials is the difficult part.

First off you would want a diamond drill bit, 18 mm is what i used: http://www.ebay.com/itm/1pc-Diamond-Tile-Glass-Hole-Saw-Drill-Bits-18MM-/170891329634?pt=LH_DefaultDomain_0&hash=item27c9eac062

Secondly You would need a scientific boiling flask, usually expensive, but i found nice prices on amazon! This is what i would use now if i knew about the length of the neck previously: http://www.amazon.com/213L15-Karter-Scientific-Florence-Boiling/dp/B006VYY49C/ref=pd_sbs_indust_2

Thirdly Downstems are a must! http://www.ebay.com/itm/200960416812?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

And the grommet(black rubber thing between down stem and boiling flask)you should be able to find one that fits your hole size at a local hardware store such as osh, lowes, or home depot.

The rest of the stuff such as bowl or ash catchers you might want to check on ebay or a local head shop for prices :)

I guess I should share this pro tip, which I came up with while lamenting a broken decanter when I was opening a bottle of Monte Bello for the S5 finale of Breaking Bad:

http://www.amazon.com/PYREX-Narrow-Mouth-Erlenmeyer-Flasks/dp/B004XR5W5E/ref=pd_sim_sbs_indust_1

$25, nearly indestructible, dishwasher safe and I got 2 for less than the price of a new Reidel.

u/supersciteach 路 2 pointsr/weddingplanning

I agree with /u/notsweetenough that a 2L flask is way too big. If you a variety of other items at the table, you can get away with 250mL or 500mL flasks.

One issue I can see is that real lab ware can be pretty pricey. The first inspo photo you posted (which I love!) could easily be over $100 in lab ware alone. There are some sets on Amazon that are affordable-ish. If you want a mix-and-match thing going on, you could get this set. I would envision the larger 1L and 500mL flasks filled with fairy lights, and the smaller flasks with flowers in them. To save on costs, I would split them between two tables (with the 1L + 250mL on one table and the 500mL, 150mL, and 50mL on another). Likewise, there are equivalent beaker sets if you want to mix-and-match flasks and beakers.

If you wanted a more uniform theme, like in your second inspo photo, something like these 250mL Erlenmeyer flasks might work.

If it were me, I would probably go with mix-and-match sized flasks and beakers, with the largest ones holding the lights and smaller ones with flowers. I'd also have a separate table number with whatever science-y reference you want (plant, animal, elements, etc.). If the two candles didn't feel like they were enough, I would add on some 50mL beakers as bud vase, or colored wired balls (like in inspo #2), or fake succulents.

u/sillycyco 路 2 pointsr/firewater

Gravity/decanting, coffee filters, on up to filter paper using a buchner funnel and vacuum pump. Depends on the size of the solids and how hard they are to get out. Usually simple coffee filters is enough, and gravity over time will settle out fine particles. The filter paper and flask setup works really well, but is kind of a pain.


u/antaymonkey 路 2 pointsr/Homebrewing

I would think not. If you have a Radio Shack near you that hasn't gone out of business yet, you can get:

Here it is:

  • 1" Stir Bar
  • Computer fan with speed controller
  • Rare earth magnets


    (optional) Erlenmeyer flask

    I used a spare project box I had for the container, but a cigar box etc would work. If you want a more detailed description of the actual process let me know. I also used a spare 9v dc adapter I had lying around. Even the fan and earth magnets can be found in an old computer tower, knocking your price down to a whoppin' $5.45 for the stir bar.

i bought one of these sets and it made the whole swirling and piping parts WAY easier.

u/TonyWrocks 路 2 pointsr/Homebrewing

Like /u/suburbdad I weigh the DME in the flask, drop in the stir bar, then add tap water to volume in my 2L Erlenmeyer flask (German Pyrex). Adding the water that way gives me the chance to rinse the sticky DME that always falls to the wrong place!

I then put the flask directly on the gas stove and bring it to a boil. This process sanitizes everything involved and even does a quick hot break on the DME.

From there it goes into a bowl of ice in the kitchen sink (with sanitized foil on top) where it sits and melts the ice.

20 minutes later it's ready to spin with yeast.

u/LlamaFullyLaden 路 2 pointsr/Homebrewing

In this case I would take it off the stir plate and use a sanitized funnel to transfer the whole starter into a sanitized growler. Stick the growler in the fridge and reclaim your flask for the next starter.

I bought this flask and it has served me well. I highly recommend it (& free shipping to boot).

I ordered that one along with a computer fan, stir bar had some magnets and built a stir plate in an old cigar box. Works like a champ. No Prime on the Flask though so that part sucked.

u/RainyForestFarms 路 1 pointr/CannabisExtracts

Stuff you'll need (Prime links given)

$200 digital hotplate: amzn.com/B00AYGIFCA

$13.50 large flask: amzn.com/B00BERGESK

$9 rubber stopper to fit flask: amzn.com/B00ES3UE9C (can be had for $.50 at Fred Meyers or lab stores)

$17.49 for a hose to run from faucet to condenser: amzn.com/B000KI7VN6

$16.72 for the condenser: amzn.com/1450567898

$13.03 for a stand to hold the condenser: amzn.com/B00657N7TS

Misc you likely already have around:

Large pot or dish that can hold the flask

Cleaning sponge or rag

1/2 gallon vegetable oil

Total cost: $269.74 and maybe $20 for the misc stuff if you lack it

Preparation: This needs to be done in a temperature controlled room; the method uses slight variations in temperature to isolate out the individual chemicals, so any fluctuation in the room will hinder this. You will need to be near a sink with a running faucet. Be prepared for this method to take 24 plus hours.

Method:

  1. Place your large pot on top of the hot plate, and place your sponge or rag in the center of the pot. This will prevent a hot spot where the flask touches the pan.

  2. Fill your flask with the herb or extract you will be isolating (use extract, the results are much purer!), and place it on the sponge in the pot. Stopper the flask.

  3. Attach a hose from the stopper to the top of the condenser. Attach a hose from the faucet to the coolant intake on the condenser. Attach a hose from the coolant exhaust and let it dangle in your sink.

  4. Fill the pan with 1-2 inches of oil. Not enough for the flask to float, but enough for the oil level to be above the level of your herb or extract in the flask.

  5. Start running cold water through the condenser, and start heating the oil. To get a list of the required temps, lookup each cannabinoid on Chemblink (or wikipedia), and look for the evaporation temp listed. Start with the lowest temp and work your way up.

  6. Once the oil has reached the temp you specified, let the system run for at least 4 hours. You will begin to see resin buildup inside of the condenser. This is your isolate. Once you are satisfied that no more isolate is building up: run hot water through the condenser so the isolate melts and runs out of the condenser.

  7. Go up a heat level and repeat 5-6.

    As I said, this really only works for THC-like cannabinoids, you won't get any terps with this method without much more expensive equipment (theyll just evaporate away), and the overall loss is great enough that its unlikely youll be able to get an isolate of CBG or THCV, since they are such a small percentage of the cannabinoids, but you should have no problem getting pure THC and even CBD, assuming your starter strain has more than a percent of it. Once you have isolates you can isomerize and do other fun stuff as well.

    That said, pure THC isnt fun at all, but its a great learning experience, and you can also use the same setup to distill essential oils or liquor, which is a slightly different process but uses the same equipment (though you can sub the digital hotplate for a cheaper electric range for those purposes)

My biggest issue for the longest time was finding the right sizes for what I needed. I finally settled on this: http://www.amazon.com/gp/product/B00BERGESK/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

It's a 1000ml erlenmeyer flask, rubber stopper included. $11.95 with prime.

I definitely needed something big enough to mix in, but also for long term storage, so this works great for me. The stuff I vape needs no steeping time, so I just order specific amounts in the quantity I mix, just dump it all in the bottle, cap it, and mix. Amazon does also have flask sets you can buy if you're looking for more DIY stuff, and I have seen them with stoppers included.

Outside of basic equipment like pots, fermenters and chillers, the 2 most impactful things that will make his beer better are the following:

  1. The ability to control the temperature of his fermenting beer. So, if you can get a cheapo chest freezer to put in the basement (if you have a basement) and a cheap temp contoller (https://www.amazon.com/gp/product/B015E2UFGM/ref=oh_aui_detailpage_o04_s00?ie=UTF8&psc=1). You can find a new chest freezer for around $150 or even less if you search craigslist.

  2. Pitching the proper amount of yeast. You can get him a 2 L flask (https://www.amazon.com/PYREX-Narrow-Mouth-Erlenmeyer-Flasks/dp/B004XR5W5E/ref=sr_1_cc_1?s=aps&ie=UTF8&qid=1488125537&sr=1-1-catcorr&keywords=2+l+flask+erlenmeyer) and a stir plate....

Here are the items that you'll need, it's only like $15 for everything. The idea is basically to boil the flask to vaporize the bud inside and you'll inhale it through the hose.

If you will allow me a little tangent in the direction of /r/wine, then this one (warning: Amazon link, in case you don't want it in your history) works well as a wine decanter. It's large enough for a magnum, but wide enough for aerating a 750mL bottle, which is why I prefer it for the regular sized bottles.

Okay so as far as drinks go, check out this recipe for [color changing mad scientist drinks] (http://www.squidoo.com/mad-science-party-drinks)! and of course [these flasks] (http://www.amazon.com/SEOH-Erlenmeyer-Flask-Set-1000ml/dp/B0018OL4A2%3FSubscriptionId%3DAKIAIAA4MWUJXHBYFRNQ%26tag%3Dsquid923629-20%26linkCode%3Dxm2%26camp%3D2025%26creative%3D165953%26creativeASIN%3DB0018OL4A2) to prepare/serve them!

[these cupcakes] (http://melissabernal.com/wp-content/uploads/2012/12/sci.png) are also super cool, and if you don't have time to make them I'm sure your local bakery could whip em' up at a fairly inexpensive price. But, in all honesty, they don't look super difficult.

of course everyone needs [safely glasses] (http://www.amazon.com/Safety-Glasses-Intruder-Multi-Color/dp/B002KA00KS/ref=sr_1_9?s=industrial&ie=UTF8&qid=1404307076&sr=1-9&keywords=mad+scientist) for this party; and they come in a set of 12! how perfect!

for the walls, or doorways, you could put up this [party biohazard yellow tape] (http://www.amazon.com/Big-Mouth-Toys-Biohazard-Crime/dp/B003PM8ROG/ref=pd_sim_indust_2?ie=UTF8&refRID=16K74JMMCG67PABM8KMC), coupled with this [bloody table cloth] (http://www.amazon.com/Halloween-Party-Zombie-Blood-Tablecover/dp/B00C7Y23CK/ref=sr_1_fkmr1_1?s=toys-and-games&ie=UTF8&qid=1404307186&sr=1-1-fkmr1&keywords=fake+zombie+blood+stickers) and this [centerpiece] (http://www.amazon.com/Centerpiece-Tableware-Supplies-Halloween-Birthdays/dp/B00EFGP3LG/ref=pd_sim_t_4?ie=UTF8&refRID=0A5R2P4RS07P7GBKM34C) you could absolutely bring a zombie element;

ooo! for fun, you could have a scavenger hunt around the house/yard that's like CDC/zombie themed! If you're good at making up stories you could totally tie it into a mad scientist thing.

"It was the experiment gone horribly wrong".

damn, this is gonna be my next birthday theme.

If you're really into that zombie topper there's a whole line of [plates] (http://www.amazon.com/Zombie-Dessert-Paper-Plates-Count/dp/B00E59PN0E/ref=pd_sim_misc_3?ie=UTF8&refRID=0YEHM1WREXVDXWYSPS6B) and [cups] (http://www.amazon.com/Zombie-Party-Paper-Cups-Count/dp/B00E5ABZ8M/ref=pd_sim_t_1?ie=UTF8&refRID=1DJZ21X2W9NGCPMT8520) and [napkins] (http://www.amazon.com/Zombie-Party-Paper-Lunch-Napkins/dp/B00E5A9UDE/ref=pd_sim_t_3?ie=UTF8&refRID=18E9JR2R0B0GN70SEKG3) just like it.

ooo and here are some hand-shaped [cupcake picks] (http://www.amazon.com/12-Halloween-Monster-Cupcake-Picks/dp/B005J6RA7Q/ref=pd_sim_t_12?ie=UTF8&refRID=0DQJPRJ2SWGJDN9144KD). I'm clearly getting carried away.

Honestly, it would be super easy to tie zombies and science together. haha. Best of luck! Let me know if you wanna brain storm!

For the contest, this [knife sharpener] (http://www.amazon.com/dp/B001CQTLJM/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=187CHN9S4I1LO&coliid=I36GYDHZ9M8GCI&psc=1) would be super cool :)

Take it to the next level with these bad boys. A 1L flask is light enough to weigh your flavors into without other ingredients, and big enough to easily swirl/mix 500ml.

u/murrayhenson 路 1 pointr/firewater

Thanks! Someone else has recommended filtration and I think that something like that plus your Pectinex suggestion would do it.

This is the one i got. i thought it was a 1000ml flask but when i got it it was 2000ml.

You can get LN2 long as you have this

https://www.amazon.com/Cryogenic-Container-Liquid-Nitrogen-Straps/dp/B00UJ7E18Q

Most places that sell gases like oxygen, hydrogen, co2 etc. Just ring them up and ask.

Is this what you're referring to? The links are products from amazon

When do you know its ready and the alcohol is completely gone?

Do you reintroduce terpenes?

Since all the alcohol is evaporated do you think it's harmful? I understand you're not a doctor (maybe) and will not take your advice as gospel.

Apologies in advance if posting links is not permitted.

I have a Pyrex 2L flask (https://www.amazon.com/dp/B004XR5W5E) looking to upgrade for larger starters. Mind if I ask what you're using for the 3L starters and if you would recommend it?

Here's the link.

This is a pretty good price.

u/chadherrella 路 -8 pointsr/singing

i don't believe in warm ups...just sing the song you want to perform...make sure you execute everything correctly...if you are not going to perform scales in publc, don't sing them...if you do want to sing scales use phrasing so at least it simulates a real song.

I usually only sing never more than an hour. You naturally get tired. You can sing for more than an hour but your body will eventually tire out and even if your mind knows the correct technique your body may be too tired to execute it and you will end up losing your voice.

actually the whole session you just posted is an hour, so I wouldnt wste time on warm ups if you want to sing longer before you get tired.

​

I would also exercise the correct breathing. Purchase an incentive spirometer --> https://www.amazon.com/Voldyne-5000-Volumetric-Exerciser-Each/dp/B000PAR7KQ/ref=sr_1_4?keywords=incentive%2Bspirometer&qid=1574556171&sr=8-4&th=1

will help improve breathing
