Replacement base (without support screen) for 47 mm magnetic filter funnels.
Pall’s patented Magnetic filter funnel features a unique magnetic closure action. The magnets are enclosed in a durable base and funnel to provide an integral, leak-proof seal. Simple one-handed operation for vacuum filtration makes this essential tool a favorite of microbiologists by promoting asceptic laboratory handling techniques. The funnel features a sturdy construction that is shatterproof and can withstand multiple autoclave cycles.

No-leak magnetic seal allows one handed operation.
Polyphenylsulfone construction is compatible with anti-foaming agents and many other solvents.
Convenient, 150 mL size allows for easy fit into small autoclaves, and 500 mL size is ideal for filtration of large samples.
Sturdy and safe. Polyphenylsulfone construction provides durability and added safety at a cost less than most glass funnels.
