Qualitative Filter Papers-Grade 6: 3μm

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.

Grade 43: 16 μm*
Intermediate in retention between Grades 40 and 41, and twice as fast as Grade 40.

Typical applications include foodstuffs analysis, soil analysis, particle collection in
air pollution monitoring for subsequent analysis by XRF techniques, and inorganic
analysis in the construction, mining, and steel industries.
