Cytiva's Whatman™ 3-Piece Filter Funnel
For quick and easy filtration, Cytiva's Whatman™ 3-Piece filter funnels are available with a choice of three plates. They also come in several sizes to match your needs.
- 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. Cytiva's Whatman™ 3-piece filter funnels have been designed to complement the range of Cytiva's 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.
- A choice of three plates
