I’m currently working as lead extractor for a type 7 volatile extraction facility, and I am currently looking into setting up a cold trap for our vacuum ovens so we can protect our pumps and collect terpene content.
Is there anyone here who can recommend a good brand or model to use for this purpose? Largest capacity available is preferred, as we will be processing in bulk.
If you dont mind a bit of DIY, you can always make one with stainless tubing and swagelock fittings in a ice/glycerine bath.
Whats your budget? There are a few lab grade appliances that would work well but those typically are found in the $1-3k range. http://www.hyvac.com/Products/Filt_Traps/Dry%20Ice/Dry%20Ice%20Trap.htm
Something like this can be easily bought or fabricated. frabrication also allows you to tailor the device for your specific needs (size, volume, flow rate, QD etc)
I did check it out, but the things that sold me on the Thermo Scientific were:
KF25 flanges, wider opening for bigger flow rate, as we will be using this for multiple vacuum ovens, not just one.
Stainless attachments and catch container. I like stainless because its more durable.
Really, the glass barbed fittings were a deal breaker for me. I have no doubt it works just fine, but it’s not what we’re looking for for our application.
