3-Piece filter funnel
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.
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.
A choice of three plates
For quick and easy filtration, Whatman 3-Piece filter funnels are available with a choice of three plates. They also come in several sizes to match your needs:
