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)

>[E]very chem lab should have a good number of 150-250 mL glass beakers on hand.
>Some large size glass test tubes will come in handy, and those are relatively cheap.
>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).
>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).
>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).
>You will find a scale, accurate to at least a tenth of a gram, to be an invaluable tool.
>Some litmus or pH paper will be useful.
>Oh, and a thermometer, of course!
>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.
>A few Erlenmeyer flasks, for mixing things.
>A volumetric pipette, for making equal aliquots.
>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.
Thanks a ton for putting together that list!

You have to zoom the picture.
This was from DL:
You guys convinced me to home brew. Especially after I just did some math on what my latest $2k purchase would get me.
Putting together the list, will be refining as I learn more.
Which Bottle Top Filter?

Or
Which Pipettor?

Money is not an object. I'm not the type to do things cheaply or in a half-assed way. Lets set up the dream home brew lab now. I'll post pictures.
What to buy?
No problem. It's called an Spirometer.
You can easily buy some online like this one: https://www.amazon.com/dp/B000PAR7KQ/ref=cm_sw_r_cp_apa_i_xTbxDbMHNWBF6
My experience was different since the surgery opened up my chest more because of how extreme my sternum was indented and was pressuring my organs. HI of 9.8
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
