The increased use of high-efficiency glass microfiber filters in modern laboratories has created a demand for simple and effective filter-holding systems

  • Easily and quickly dismantled and cleaned
  • Ground flat flange sealing to ensure a good filter seal

Suitable for filtration with glass microfibre filters of aqueous solutions, funnel and reservoirs are made from borosilicate glass 3.3 with acrylic support plate. 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.

The parts can be quickly and efficiently cleaned because of the simplicity of the design.

Acrylic Plate: Supplied as standard. Suitable for filtration of most aqueous solutions. Maximum working temperature 65°C.
Polypropylene Plate: Optional extra. Recommended for most acids (except concentrated nitric acid and fuming sulfuric acid) at room temperature. Suitable also for most alcohols, glycols, ethers, and ketones. Maximum working temperature 100°C.
PTFE Plate: Optional extra. For virtually all common acids, alkalis, and solvents at temperatures up to 100°C. Maximum working temperature 200°C.

Whatman 3-piece filter funnels have been designed to complement the range of Whatman fine particle retention, rapid flow rate glass microfiber filters.
