Thanks for the response... This weekend will be the trail run..Airgas will rent you a dewar with a 500 dollar deposit so assuming we dont break the thing whilst extracting all should be well. I believe their quote for Liquid N2 was $10 a liter.

I will make a post on Sat after we hopefully yield some very pure cannabinoids. Previously using lab grade hexanes to extract and distilling to recover hexanes works quit well and the product is great, but waxes and chlorophylls are still carried through to the final product regardless of sep funnel washes.
thekenw Reviewed by thekenw on . Employment I am a legal grower of cannabis in the great state of Oregon. I will be finishing up my B.S in Advanced Chemistry w/emphasis in Biochemistry. Are there any jobs in northern California that might utilize my expertise in Chemistry? My passion is the phytochemistry of cannabis, among other psychotropic substances. As a chemist I of course have developed methods for the extraction and purification of cannabinoids, and am very eager to learn evermore efficient techniques. Cheers, Dr. K Rating: 5
