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 50: 2.7 μm*
Retention of very fine crystalline precipitates.

The thinnest of all Whatman filter papers with a slow flow rate, these filters have a hardened and highly glazed surface, which also keeps the paper free from loose surface fibers.

Highly suitable for
qualitative or quantitative filtrations requiring vacuum assistance on Büchner
or 3-piece filter funnels.

Very strong when wet and will withstand wet handling and
precipitate removal by scraping.

In the electronics industry, the virtual absence of
fiber shedding is utilized in carriers for integrated circuits.

This grade is also available in Smear Tab format for wipe testing (e.g. testing of
surfaces for radionuclide contamination).
