Best evaporation & drying equipment according to redditors

Hey guys as a heads up. In the lab if we make silicone we always degas the mixture before pouring. To degas just put the silicone after mixing into a closed container and pull vacuum. I think even a cheap aspirator will pull enough vacuum to work. Pull until the bubbles stop than you're good to go.

Both look promising. Google degassing silicone for more it's a common technique in soft litho.

Edit: For a chamber just get a plastic dessicator. They aren't that expensive : https://www.amazon.com/United-Scientific-55204-Polypropylene-Polycarbonate/dp/B00ES3GPMM

Edit3: Decent part combo for degassing

Remember keep the vacuum so that it slowly degasses you do not want it to bubble over and all into your chamber.

You would need a desiccator and some tubing. I bought my desiccator on amazon. The tubing can be bought at Home Depot.

Here's the link for the desiccator:

If you need it today harbor freight or home depot would be the places to go. Depending on how nice of one you get you may also need to buy a gauge the hardware store should have one or you can buy a brake bleeding pump with one. the whole set up should look like this. I would recommend getting a real desiccator you can find them on amazon for not to much, before I had one I just used a mason jar with a food savor lid, you could just poke a hole in the top of the normal lid with a screw driver and put one of the suction tops that came with your pump over it if you can't find a food savor one. Its worked fine for me but some people don't think its safe to vac a mason jar so don't make a habit out of it

A vac chamber with a heat mat is cheaper.

careful with designs like this, horror stories of jars popping should lead you to get the correct equipment. This and this

Get a desiccator

• pull vac in the desiccator, close valve
  
• connect desiccator to funnel
  
• open valve, bam passive shit right thur
  
  I also recommend using this funnel
  and this flask.
  
  Hope this helps. I got these tips off Bret Maverick's IG. So I don't take cred, just spreading the love.

Through a series of mechanistic steps to remove all the cannabinoids separately. They probably use some type of fractional method.

https://www.projectcbd.org/sites/projectcbd/files/downloads/cannabinoid-boiling-points-thc-cbd.pdf

Here you can see that there is variation the BP of cannabinoids. One way to fraction them (I.e. separate) is to first use a solvent they all have a high affinity for, extract them out of the flower matrix (I.e. the nugs), then heat the mixture in an apparatus with some type of fractional set up (similar to how to beer is distilled). A really basic set up would be to use a KD with a snyder column. As the mixture heats up and begins to escape into the gas phase, it will hit resistance at the balls in the column and be condensed back down into the KD. As the heat increase, molecules with lower BP will be able to escape past the balls of the column first, while heavier molecules will take more time. You would hook up another piece of glass wear that collects the distillate.

This is a really simple scenario and I doubt it's exactly what they use, but the framework is likely the same.

Cheap and quick version? go with a hamster ball for the exterior and suspend the ball using some fishing line. However if you really want to do it right I would go the resin route.

A few suggestions from experience when working with resin. work in a WELL VENTILATED AREA. resin stinks bad, and given enough time it will kill you. so lots of fresh air.

Secondly, if this is something you are going to be doing on a semi regular basis i would suggest investing in a degassing chamber. when you see clear resin that is hazy its either because of tiny air bubbles or a poor mix, the degassing chamber will pull all the air out of the resin and will help get the clearest results possible.

Finally, when actually pouring the resin do not pour directly onto the interior model. pour onto the bottom of the mold and allow the resin to rise up to the interior model. this will reduce the amount of trapped air that can form bubbles around the model itself. (not a great look)

Now specifically to your model IF you do go the resin route you will need to have a spherical rubber mold that you will have to secure your interior model to (much like the hamster ball with some fishing line) if you don't secure it in the mold it will just rise to the top and ruin the look. Also making sure you choose a good location for your pour and drain spouts will be very important as they will need to be cut off and sanded flush later. You can do some great work with 2000 grit sand paper but it wont come out perfectly clear. So I would put the pour / drain spouts where you intend to hold it.


I hope this helps, it was a bit ranty but man I love pouring resin.

How small are we talking? A 1.5cfm pump can drop one of these to full vac pretty quick. Need to keep an eye on the muffin height though.
