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.
Grade 54: 22 μm*
Very fast filtration and high wet strength makes this grade very suitable for vacuum
assisted fast filtration of difficult coarse or gelatinous precipitates.
Grade 42: 2.5 μm*(Ashless Grades)
Used for critical gravimetric analysis with the finest particle retention of all
Whatman cellulose filter papers.
Typical analytical precipitates include barium sulfate, metastannic acid, and finely precipitated calcium carbonate.
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.
