Sartorius Biosart 250 Funnels Sterile PK50

The major area of application for Biosart™ 250 Funnels is microbiological analysis of relatively large sample volumes that have a low number of microbes, with membrane filtration being an essential step. They are suitable for testing smaller volumes by placing a sample in a few ml of sterile physiological NaCl solution. Designed for microbiological testing of pharmaceuticals, food, beverages, water, and other liquids. They are sterile, ready to use 250 ml plastic funnels designed to be placed onto the bases of a vacuum manifold. A Sartorius gridded membrane filter is placed on a stainless steel filter support. A Biosart™ 250 Funnel is simply fitted on and the sample is filtered. The funnel is made of polypropylene and is sufficiently elastic for optimal sealing with a bayonet-type closure. Graduations are marked at 50, 100, 150, and 200 ml for sufficiently exact sample volumes. The large inner diameter ensures a high flow rate. The conical form allows a thorough rinsing of the system subsequent to filtration. No liquid is retained in the filter funnel. Biosart™ 250 Funnels allow quick performance of the filtrations required in the routine.
