Whatman™ 3-Piece Filter Funnels for Glass Microfiber Filters
Whatman™ reusable 3-Piece filter funnels have been designed to complement the range of Whatman™ fine particle retention, rapid flow rate glass microfiber filters. The increased use of high-efficiency glass microfiber filters in modern laboratories has created a demand for simple and effective filter-holding systems. This reusable filter 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.
For quick and easy filtration, Whatman™ 3-Piece filter funnels come standard with an interchangeable acrylic filter funnel plate. The acrylic filter funnel plate is suitable for filtration of most aqueous solutions with a maximum working temperature of 65°C. (Both Polypropylene and PTFE interchangeable filter funnel plates are available separately in different sizes to match your needs.) Filter Funnel Plate: Acrylic. Multiple sizes of funnels & matching reservoirs are available.
