Qualitative Filter Papers-Grade 4: 20-25μm
Availability:
10 in stock
Extremely fast filtering with excellent retention of coarse particles and gelatinous
precipitates such as ferric hydroxide and aluminum hydroxide.
Very useful as a rapid filter for routine clean-up of biological fluids or organic extracts during analysis.
Used when high flow rates in air pollution monitoring are required and the collection of fine particles is not critical.
Available prepleated as Grade 4V.

Qualitative Filter Papers-Grade 3:6μm
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.
