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.

Whatman chromatography paper media are made from specially selected cotton cellulose.
They are rigorously quality controlled for characteristics important to the chromatographer and to ensure uniformity within
the grade.
Features and benefits
• Pure cellulose produced entirely from the highest quality cotton linters
with no additives of any kind
• Manufactured and tested specifically for chromatographic techniques –
this ensures the wicking capability and uniformity of capillary action that
are important in chemical separations
• Also widely used in protein and nucleic acid blotting
Nuclepore track-etched polycarbonate membranes are manufactured from high-quality polycarbonate film and have sharply defined pore sizes, high flow rates, and excellent chemical and thermal resistance.
The membranes have a smooth flat surface and exhibit very low levels of extractables.
Grade 5: 2.5 μm*
The maximum degree of fine particle filtration in the qualitative range.
Capable of retaining the fine precipitates encountered in chemical analysis.
Slow flow rate.
Excellent clarifying filter for cloudy suspensions and for water and soil analysis.
Also available prepleated as Grade 5V.
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.
