Filter Paper 11 cm Lab Qualitative Filter Paper for Chemistry, Standard Grades 1, 2, 4 - ZENPORE Fast, Medium, Slow Flow 110 mm (Bundle of 3 x 100 Discs)
GRADE 1, 2, 4 STANDARD Qualitative Filter Paper Equivalent to Whatman grade 1, 2, 4, these laboratory filter paper are used for a broad range of filtration when you need to separate a solid or precipitate from the filtrate. Made from high alpha-cellulose cotton, these standard lab filter are not intended for ashing.APPLICATIONS Depending on the grades, these filters have many applications, for example:science : From clean-up of insoluble liquids to routine clarification of suspensionfood : From solid foodstuffs separation and liquid extraction to fat content determinationbeverage : From filtration of musts, pulps and syrups to malt analysisagriculture : From soil pre-filtration to analysisenvironment : From monitoring of fast flowing exhausts to smoke pollutionCOARSE TO HIGH RETENTION Retains fine, medium and coarse precipitates depending on grade used, for example:Grade 1 : Metal Sulfates (Pb, coarse form of Ba and Ca)Grade 2 : Metal Sulfides (Cd, Ni, Zn, Fe, Pb, Mn, Ag, As) Grade 4 : Metal hydroxides (Al, Cr, Fe, Mg) , Be Oxidepaper : pure cotton celluloseflow : slow, medium, fastretention : 5~10, 10~15, 20~25 μm (fine, medium, coarse)speed : 15~20 s (10ml DIN 53137)size : ⌀ 110 mmthickness : 140-160 μmweight : 86 g/m²ash : 0.1%qty : 300 discsPLAIN-DISCS These Flat Discs are suitable for gravity and Buchner low suction vacuum filtration. The same affordable filters are also available funnel-ready prefolded or prepleated.EQUIVALENCE & SIZE See the cross-reference table and size diagrams in the photos to choose the appropriate reference and diameter of your circles.
