Filter Papers

Whatman Grade 2 filter paper is slightly more retentive and absorbent than Grade 1 with a corresponding increase in filtration time (i.e. slightly slower filtration speed). In addition to general filtration in the 8 m particle size range at 98%...

Whatman Grade GF/A Glass Microfiber filers offer fine particle retention and high flow rate, as well as good loading capacity. They are used for high-efficiency general purpose laboratory filtration, including water pollution monitoring of effluents, for...

Sterile filter paper disks (diameter 6mm) impregnated with o-nitrophenyl-?-D-galactopyranose

These cellulose filters are used in qualitative analytical techniques to determine and identify materials. 90mm diameter circle sheets. The most widely used filter paper for routine applications with medium retention and flow rate. This grade covers a...

Time-saving Whatman qualitative grades are offered in this convenient form, which gives major advantages over flat circles. Comparable to Grade 858 but with a smooth surface, slightly thinner and faster. Also available flat stock form as Grade 86...

Recommended when fast filtration of a gelatinous precipitate for gravimetric analysis is performed on a strongly acidic or alkali solution. Whatman Quantitative Filter Paper: Grade 541 Circles are acid hardened cellulose filters, which reduces ash to an...

These cellulose filters are used in qualitative analytical techniques to determine and identify materials . Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat...

These 240 mm diameter fast filtering, black dot filter paper discs are used for quantitative and gravimetric analyses as well as for pressure or vacuum filtration. They are made out of 100 % cotton linters with an a-cellulose content of > 98 % and...

These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters...

Whatman® Grade GF/C Glass Microfiber filters combine fine particle retention with good flow rate. It is the standard filter in many parts of the world for the collection of suspended solids in potable water and natural and industrial wastes...

These cellulose filters are used in qualitative analytical techniques to determine and identify materials. Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters...

Binder-free glass microfiber filters are recommended for analytical and gravimetric analyses and also as prefilters. These filters combine fast flow rates with high load capacity and the retention of very fine particles; they are biologically inert, are...
