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.

  • Glass sealing flanges are ground flat to ensure a good filter seal

  • Edge clamping prevents peripheral loss and possible passage of solution around, rather than through, the filter circle
  • Parts can be quickly and efficiently cleaned
