Cytiva Whatman™ Three-piece Filter Funnel

Description

Features quick and easy filtration. Whatman™ Three-piece Filter Funnels dismantle quickly for the insertion of a new filter. Funnels are available with a choice of three plates and come in several sizes.

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
