This is a Whatman 90mm polypropylene disc accessory (1950-109) for a glass microfiber filtration apparatus.The item is in brand new condition in its original packaging. Why pay $100 for the same new item? From the manufacturer: 3-Piece filter funnel 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. Functional design 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. Positive filter clamping 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.
