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.

Grade GF/C: 1.2 μm*

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.
