Whatman 1825-142 Filter Circles, 142mm Dia, Binder Free Grade GF/F, 25/pk (PN:1825-142)

These glass microfiber filters are designed for fine particle retention and high-performance filtration, commonly used in environmental testing, biochemical sample preparation, protein purification, and DNA binding applications.

Grade GF/F filters provide approximately 0.7 µm particle retention, allowing efficient removal of very fine particles while maintaining fast flow rates for laboratory workflows.

These filters are made from binder-free borosilicate glass microfiber, which ensures high purity, low extractables, and excellent chemical resistance for sensitive analytical applications.

GF/F filters offer high loading capacity, rapid flow rate, and strong retention of fine particulates, making them ideal for filtering difficult or particle-rich samples without clogging quickly.

Yes. Glass microfiber filters like Grade GF/F can withstand elevated temperatures (up to ~500–550°C), making them suitable for gravimetric analysis, ignition procedures, and environmental testing.
