Purging Winterized BHO

The drierite is a different salt, calcium sulfate..it should be better than table salt, nacl and water softener kcl would be better than table salt also...the molecular sieve is best that I linked. The caso4 should work nicely..as long as their is no cobalt. I know some drierite has cobalt..

The one you listed is pretty interesting. I was thinking of picking up a lb perhaps.. Looks like it's around $20 for the sieve you linked and for the caso4. Maybe I should use the KCL since it's a bit cheaper and this is just a one time thing really..

You do like that...just keep dissolving salt in till it all sinks to the bottom excess salt just sinks..yes a small amount of salt will be absorbed into the alcohol. Which is why its not the preferred method but. I've done it and I think a few have done it with iso around here too..
But you shake shake and let the layers separate just like in the link and siphon away...cleared it

Saybian ..don't worry about solvent accessible surface area....and I always prefer the branched chain isobutane

could that small amount of salt be removed with a .2 micron syringe filter?

Here's a list...no you can't filter that small of a particle..

But if you could get a filter small enough yes you could...

interesting, they have "how to make graphene sheets" on youtube
thanks for the info qwiz

So I was wondering, I used 151 everclear to winterize.

What's going to be the difference when using 151 everclear as opposed to 191? I know one has less water content so it's easier to purge but what's the process I should go through when dealing with 151 everclear?

at the moment I dissolve my purged BHO into 151 everclear and stir it up in a hot water bath until the BHO dissolves, Put that into the freezer for about 24 hours, strain it through a coffee filter while it's in the freezer, slowly.
I then wait another 24 hours after all the everclear is strained to wait and see the waxes solidify a little more. I then pour that over a pyrex in a thin film and place it in a water bath @ 90-100F with a fan blowing over it. It usually evaporates in an hour or so, and after that I just scrape what seems most of the time to be shatter since it's hard and is pretty damn difficult to scrape. I then clean off each razor blade and melt that wax into a small puddle over the skillet with a oil slick and towel to manage the heat. I then place that into the vac chamber which is in a water bath at about 150 so the chamber is at 90-100F the whole time while I purge at -29 inHg for about an hour.

Should I be changing anything in my methods? I just ordered some 190 everclear online but I used 150 for my last batch and was wondering if I need to refine anything. Thank you in advance for everybody who answers this.
