Product Description

A GL32 PBT cap with a PTFE-faced silicone ring connects the adapter to the filtration assembly, while a GL45 PBT cap with the same type of ring seals onto the bottle. A PBT hose connection accepts 1/4 in ID flexible tubing for the vacuum line. Glass parts are WHEATON 33 low extractable borosilicate meeting USP Type I and ASTM E438 Type I, Class A.
