Custom supercritical CO2 chamber with easy-to-use lid clamp

I built another supercritical CO2 chamber for extraction and drying. This time, I wanted a chamber that was easier to open and close, and could be expanded to larger volumes with the same closure system. The chamber is built from 2" OD .25" wall stainless steel, and I welded a plug into one end and a ring with O-ring gland onto the other.

    Hi Ben,
    Do you have an idea of what liquid they'd be using for supercritical extraction at seemingly room temp in this vid:

    Dj, it certainly looks like CO2. They didn't heat it, so the CO2 was liquid, not really supercritical.

    It is a butane extractor.
