people that make shatter

I have the extraction tube and a vacuum pump and chamber. It's a 1 stage 3cfm. Do I still have to double boil the product after blasting or can I put it right in the chamber?

I’d double boil. I would be worried the muffin would expand onto the walls of your chamber and make a mess

I make my shatter with ethanol, but I always utilize a heated crucible to warm my crude before purging.
My etoh pro does a great job of recovering the alcohol, as well as post-processing.

Don't double boil it.
Do you have a heating pad on it with control?
