Whatman 1950-009 3 Piece Filter Funnel for Glass Microfiber Filter, 200mL Capacity, 90mm Diameter

The increased use of high-efficiency glass microfiber filters in modern laboratories has created a demand for simple and effective filter-holding systems. Whatman 3-Piece filter funnels have been designed to complement the range of Whatman fine particle retention, rapid flow rate glass microfiber filters. Functional design: Three-piece construction. The funnel is quickly dismantled ready for the insertion of a new filter. The glass sealing flanges of the funnel and reservoir are ground flat to ensure a good filter seal. Positive filter clamping: All retained solids are deposited within the filter circle. Edge clamping prevents peripheral loss and possible passage of solution around, rather than through, the filter circle. Simple to clean: The parts can be quickly and efficiently cleaned because of the simplicity of the design. Filter dimensions: 9cm. Effective filtration diameter: 7cm. Effective filtration area: 38.5 cm sq. Filter support plate diameter: 9cm. Filter funnel height: 17.9cm.
