Description & Specifications

Specifications

Includes Acrylic plate

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; funnel is quickly dismantled for insertion of a new filter
  • Glass sealing flanges are ground flat to ensure a good filter seal
  • 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
  • Parts can be quickly and efficiently cleaned
Choice of Three Plates
  • Acrylic - 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 temperatures; suitable also for most alcohols, glycols, ethers and ketones; maximum working temperature 100°C
  • PTFE - For virtually all common acids, alkalis and solvents at temperatures up to 100°C; maximum working temperature 200°C
