Product Description
Clean release of the membrane after sterilization starts with the right funnel. This 300 mL PTFE-faced glass funnel replaces the upper half of a 47 mm sterile filtration assembly, preventing filters from bonding to the glass when the unit is autoclaved with the membrane installed.
This listing is for Wheaton catalog number 419374: 300 mL PTFE-Faced Glass Funnel for 47 mm Assembly. The funnel's sealing face is coated with PTFE and mates with a PTFE-faced fritted support base under a clamp. Its 300 mL reservoir accommodates large sample pours, and the glass body can be cleaned and reused. Pair it with the matching base and clamp to complete or repair the assembly. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
