PTFE Adapter, Ground joint NS 45/40 to GL45

The DURAN® PTFE Adapter combines the ground joint NS 45/40 of the filtering apparatus with the GL 45 screw thread of the DURAN® laboratory bottles. Product benefits: The adapter allows the filtrate to be directly collected in a DURAN® GL 45 laboratory bottle which reduces the risk of contamination. Note: As a vacuum is generated within the bottle during filtration, the use of DURAN® pressure plus+ bottles is highly recommended.
