Not sure if it's a tip or trick but I found that using more than 1 coffee filter on the end of your tube is unnecessary and can lower your yield by trapping BHO & sponging it up instead of filtering it out.

multiple coffee filters are good when someone is working with realy fine powdered material (not recommended)

but i agree one is enough.. i still fold my one coffee filter up, get about 3-5 filtrations through just one..

and as for oil getting trapped in the filters. i now take my filters from the very previous run, and pack them into my next tube to blast... this is a good trick right here for more yield..

alright now what about a heating source for the vaccuum chamber? Every griddle I purchase heats up too hot!! Where can I find one that will stay at 100 degrees??????

you wont find a cheap one easily for what you want..

so instead, your best bet is to take that cheap griddle. and use its lowest settings.. the thicker the space between your griddle and vacuum, the less heat will transfer..

i use sand under my vacuum chamber to kill the heat, and distribute it evenly.. some use water...

my favorite thing is to create a small oven cabinet... with a space heater, sealed cabinet and fan..

i can adjust temps in the cabinet anywhere from 60F to 120F precisely. i loveee this setup. lets me place multiple vacuum chambers inside one cabinet...

This sounds all too complicated to me! I have the money so what is an option that would be 'not cheap'??

The expensive option would be to go for an electric stove top with a temperature control.

Like one of these: 1 2 3

You're still going to need to use sand to control the heat just a little bit more. It helps keep the chamber at a low temp throughout the whole process because direct heating is just not as good.

yea we have i guy on here that use an induction cook top, i think the end result was burnt parchment paper, Guz you do remember seeing that?
i think that guy put the paper right on to the cook top not in a vac chamber

yes, they are kind of expensive, big and clumsy though. Remind me of the first cell phones. Does work good though.

I get good results using a silicone heat mat, which I control with a PID controller and type J thermocouple.

I get reasonable results using a silicone heat mat and Variac variable transformer, but it doesn't track as well.

We order our mats custom made in China, but you can pick them up at Omega and Briskheat.
