Cytiva, 1822-150, Whatman™ Grade GF/C glass microfiber binder free filter, 150 mm circle (100/Pk)

Cytiva Whatman Grade GF/C is a binder-free glass microfiber filtration medium supplied as 150 mm circular filter papers. Each pack contains 100 circles for laboratory workflows that require collection of suspended particles or clarification of suitable liquid samples. The microfiber structure provides a relatively high loading capacity and is widely used for collecting suspended matter in environmental and analytical sample preparation. A nominal particle retention rating near 1.2 µm characterizes the grade, but this rating should not be interpreted as a validated sterile membrane pore size. Select the filter diameter to match the funnel or filter holder and seat the circle evenly to avoid bypass. Where the method permits, pre-rinse or precondition the filter to control background contributions. In gravimetric measurements, follow the prescribed drying, conditioning and weighing sequence so the filter mass is reproducible. Handle the glass fiber carefully to avoid shedding or damage. These circles are binder-free filter media, not individually sterilized syringe filters or hydrophobic gas-vent capsules.
