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).
Puradisc syringe filters combine premium quality and economy.
They are used for the quick, efficient filtration of samples up to 100 mL volume.
Puradisc filters are produced from pigment-free polypropylene or polycarbonate with standard inlet (female luer lock) and outlet (male luer) connections (unless otherwise stated).
Options include a sterile, medical-grade blister pack for critical applications and a special tube tip outlet that allows the sample to be accurately
Dispensed into a micro-vial, removing air lock.
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 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.
