Cellulose filters are used in qualitative analytical techniques to determine and identify materials.
Prepleated qualitative filters are also available, which give improved flow rate and increased loading capacity compared to equivalent flat filters.

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 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).
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.
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.
Grade 93: 10 μm*
This filter paper is intermediate in speed and retention between Grades 1 and 4.
Available in a dispenser pack, which can be attached to the wall or bench, placed on a
shelf either upright or flat, and used as a normal carton or as a convenient dispenser.
The envelopes are released individually for easy one-at-a-time removal.
Package and envelopes are clearly marked for size and content.
