Hexane has been unpredictable for me in the seperatory funnel in terms of repeatable results. Generally the whole process is about 15 minutes or less. Purged the pentane/hexane, the oil hasn't changed its color, it was still black. do a vac purge? Would have a question for you.

Control Parameters: 109-66-0, Pentane, NIOSH TWA 350 mg/m3 109-66-0, Pentane, ACGIH TLV TWA 600 ppm 109-66-0, Pentane, OHSA PEL TWA 1000 ppm Appropriate Engineering controls: Emergency eye wash fountains and safety showers should be available in the immediate vicinity of use or handling. I will post pics of my crystals when they are bigger. Neem oil with azadirachtin has been given to children orally in the Far East for various remedies for a very long time. does not really works, am I understand it morrect? Plus, putting your jewelry away safely while you bake, apply cosmetics, or garden helps keep debris from building up in and around the setting. If you intend to produce a THCA crystalline with above 99 percent purity, you will need to perform these washings. In a nutshell, many water soluble non cannabinoid ingredients come along for the ride when a polar solvent is used and water is present. An easy way to get rid of them is to simply re-dissolve the non-polar extraction in 190 proof (~95.5% azeotropic) polar ethanol and stick it in the freezer for about 48 hours at -18C/0F, for the waxes to coagulate. Polishing extracts | Skunk Pharm Research D Gold, Author of Cannabis Alchemy, 1971, Shares Cannabis Extraction History Unfolding!

The good news is that if you are out of the stink or taste, you are less than about .01% of TLV, but the bad news (?) The different chemical weights and properties seem to make them separate into distinct layers as the iso/water mix resolve into different layers (water on bottom). C over the course of 5-30 days. Are you up for a challenge ? . D. Gold. By googling, I learned (contrary to my vast knowledge beforehand lolz) that some things, like iso and water, cannot be separated by distillation.

It runs smooth and pure at this point and doesn't snicker or pop when dropped through a flame (Bix). GW, Hi I have heated extract in the oven at 300 F in a glass container. I hope all this helps.

They worked well for our purpose, and we cleaned them when they clogged, by alternating a hot aqueous NaOH solution and a HNO3 solution, to break organic bonds.
