Qualitative Filter Papers-Grade 6: 3μm

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.

Offers fine particle retention and high flow rate, as well as good loading capacity.

Used for high-efficiency general purpose laboratory filtration, including water pollution monitoring of effluents, for filtration of water, algae and bacteria cultures, food stuff analyses, protein filtration, and radioimmunoassay of weak ß emitters.

Recommended for gravimetric determination of airborne particulates, stack sampling, and absorption
methods of air pollution monitoring.
