79 Chemistry Glassware
47mm Filtration Assembly with GL45 Thread Connection ■ Designed to collect the filtrate directly into a standard laboratory bottle ■ Connection to the bottle is made with a polybutylene terephthalate (PBT) cap and a PTFE-faced silicone sealing ring ■ Glass components are manufactured from WHEATON 33 low extractable borosilicate glass that conforms to ASTM E 438 Type I, Class A requirements
Filtration Adapter Assembly ■ Filtration adapter assembly makes it easier to connect standard 47 and 90mm filtration assemblies with stopper connections to a standard laboratory bottle with a GL45 thread ■ Replaces the stopper to make the connection to the bottle ■ A GL32 PBT cap with a PTFE faced silicone sealing ring makes the connection to the filtration assembly ■ A GL45 PBT cap with PTFE faced silicone sealing ring then makes the connection to the bottle ■ Includes a PBT hose connection for use with 1/4” (6mm) I.D. flexible tubing
With Fritted Glass Support ■ Recommended for general filtration
