This well-made Bee Hive Extraction Tube is made of heavy-duty SCHOTT glass only and not inferior Chinese glass like other products on the market. The flared end of the blast tube paired with the stainless steel butterfly clamp will hold your preferred filter of choice snug in place. The butterfly clamp features a hand knob that can be easily hand tightened so no need to fumble with a screwdriver or other tools.
