Hello everyone, have a few questions regarding set up I have access to fresh material and I will be doing EVERYTHING outside. This is the vacuum pump I am considering, is this guy gonna cut it? http://www.ebay.com/itm/New-Single-...259?pt=LH_DefaultDomain_0&hash=item58a1a86713 here is the chamber I am considering, will it hold up? http://www.ebay.com/itm/Glass-desic...d=100005&prg=7926&rk=3&rkt=5&sd=380683902551& But I would have to say my biggest question is do I need to apply heat to the pyrex brownie tray im running the BHO into? if so, how do I do this safely being that there will be BHO fumes in the atmosphere? I.E. does the tray go on the hotplate/griddle? or into a double boiler bath system? In either case what temperature range is optimum for the water/hotplate (farenhiet please)? Also how long do I leave it on/in the hotplate/double boiler bath before moving into the vacuum pump? Then my final question would be is there an equation to figure out how long to vacuum purge the BHO? as in __x_amount of time for _x__ amount of BHO? Thanks!
