Stainless steel vacuum filtration unit for 50/47 mm membrane filter, with 100 ml funnel capacity

Stainless Steel Filter Holders

Stainless steel holders differ in their funnel capacity (choice of 40 ml, 100 ml or 500 ml) and in their valve type (part numbers ending with CS feature sterile venting). They are specifically designed for applications in which particles or microorganisms need to be retained on the surface of membrane filters. Their stainless steel frit filter support ensures uniform distribution of the retained particles over the entire surface of the membrane filter. Special features facilitate the use of these filter holders during routine testing. Their stainless steel taps are easy to turn on and off, and only one hand is needed to use the unique clamp for secure fastening or convenient removal of the funnel.

Glass Filter Holders

These filter holders are available with a 30 ml funnel (filter dia. 25 mm) for small-volume filtration or with a 250 ml funnel (filter dia. 47|50 mm) for large-volume filtration. They can be sterilized by autoclaving (max. 134°C) or by dry heat (max. 180°C). The glass frit ensures uniform distribution of retained particles.

Polycarbonate Filter Holders

Type 16510 is complete with a receiver flask, and can be used with vacuum or low pressure (0.5 bar|7.3 psi is recommended for maximum throughput). Type 16511 is the same as 16510, but without a receiver flask. It is designed for use on a suction flask or a vacuum manifold (e.g. Combisart® systems). Both types can be sterilized by autoclaving (max. 121°C).
