Description

Glass microfiber filters
Whatman glass microfiber filters are manufactured from 100% borosilicate glass and are available with or without binder. These depth filters combine fast flow rates with high loading capacity and the retention of very fine particles, extending into the sub-micron range. Glass microfiber filters can be used at temperatures up to 550oC and are excellent for use in applications involving air filtration and for gravimetric analysis of volatile materials where ignition is involved.
Whatman Multigrade GMF 150 is particularly valuable for the prefiltration of larger volumes and solutions that are normally difficult to filter.

Binder-free glass microfiber (GMF) filter papers
Grade GF/C (1.2 um*)
Combines fine particle retention with good flow rate. The standard filter in many parts of the world for the collection of suspended solids in potable water and natural and industrial wastes. Fast and efficient clarification of aqueous liquids containing low to medium levels of fine particulates. Widely used for cell harvesting, liquid scintillation counting, and binding assays where more loading capacity is required. Ready-to-use (RTU) formats available for total suspended solids (TSS) and total dissolved solids (TDS).
