Qualitative Filter Papers-Grade 6: 3μm

Grade 3: 6 μm, (Medium flow, thick filter paper)

Double the thickness of Grade 1 with still finer particle retention and excellent loading capacity; more precipitate can be held without clogging.

The extra thickness gives increased wet strength and makes this grade highly suitable for use in Büchner funnels.

The high absorbency is particularly valuable when the paper is used as a sample carrier.

Grade 5: 2.5 μm*
The maximum degree of fine particle filtration in the qualitative range.

Capable of retaining the fine precipitates encountered in chemical analysis.

Slow flow rate.

Excellent clarifying filter for cloudy suspensions and for water and soil analysis.

Also available prepleated as Grade 5V.
