Whatman
Filter Funnel Plate, PTFE, 70mm, 1 Pk SKU: 1950-117

Whatman 3-Piece Filter Funnels are ideal for quick and easy filtration using high-efficiency glass microfiber filters.

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. 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.

• Chemically resistant - 3-Piece construction consists of glass cylinder and base with a polymeric membrane support.
• Support options - Provided with acrylic support and optional polypropylene or PTFE supports available separately for some sizes.
• Secure sealing - Clamps at edges to prevent peripheral loss due to fluid bypass around the edge of the filter.
• Eliminate carry-over - Simplicity of design facilitates easy and thorough cleaning between use.

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. The unit consists of a glass funnel and base, acrylic support platform, and 3 easy-to-apply metal clips. The range of diameters, funnel sizes, reservoir volumes and alternate support platforms provides a flexible system to meet the varied and unique needs of busy laboratories.
