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.
Whatman gridded filters have clearly defined grid lines spaced at 3.1 or 5 mm intervals.
The special ink used is nontoxic and completely
free from bacterial growth inhibitors.
Whatman black mixed cellulose esters are available plain for automatic colony
counting applications, as well as gridded to assist in manual counting procedures.
Black membranes provide contrast between residue or cell colors and the filter
without having to counter-stain the membrane.
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.
Grade 40: 8 μm*
The classic general purpose ashless filter paper with medium speed and retention.
Typical applications include gravimetric analysis for numerous components in cements,clays, iron, and steel products; as a primary filter for separating solid matter from aqueous extracts in general soil analysis; quantitative determination of sediments in milk, and as a pure analytical grade clean-up filter for solutions prior to AA
spectrometry.
Also used as a high-purity filter in the collection of trace elements and radionuclides from the atmosphere.
