Product Description
Filtering straight into a storage bottle saves a transfer step and cuts the risk of contaminating the filtrate. This PTFE adapter links a filter apparatus with a 45/40 ground joint directly to a GL 45 laboratory bottle, so the filtered liquid lands in its final container.
This listing is for DURAN catalog number 294001207: GL 45 PTFE Adapter, NS 45/40 - GL 45, with EPDM Seal. Machined from PTFE with an EPDM seal, the adapter has an NS 45/40 joint on one end and a GL 45 thread on the other. It is designed for use with pressure-rated laboratory bottles during vacuum filtration and avoids the need to refill from a flask. The adapter is autoclavable and measures 53 mm in diameter by 67 mm high. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
