Magnetic Filter Funnels, 47 mm, Pall® Life Sciences
For vacuum filtration of liquids, especially for the analysis of aqueous samples for microbiological and particulate contamination using the Membrane Filter (MF) Technique. The Magnetic Filter Funnel is ideal for use with a filter funnel manifold or side-arm vacuum flask using a rubber stopper connection.
Dual magnets ensure a tight, no-leak seal between the funnel cylinder and base, eliminating the need for cumbersome clamps. The design allows one-handed operation and prevents possible twisting and tearing of the filter membrane. A ridge on the base guides and holds membrane in position. Forcep access points provide easy retrieval of the filter. Durable, chemically resistant polyphenylsulfone plastic construction resists breaking. The cylinder is marked with external graduations for ease in measuring sample volume and to ensure a smooth inner surface for rinsing. Washable, autoclavable, and UV compatible.
