Qualitative Filter Paper 15 cm Quadrant Folded Filter Paper, Qualitative Grade 1 - ZENPORE Medium Flow 150 mm (50 Discs) 15 cm diameter
Qualitative Filter Paper 15 cm Quadrant Folded Filter Paper, Qualitative Grade 1 - ZENPORE Medium Flow 150 mm (50 Discs)
GRADE 1 Q QUADRANT Qualitative Filter Paper Equivalent to Whatman grade 1 FF, this pre-folded filter paper is commonly used in labs where you need to separate a solid or precipitate from the filtrate. Made from high alpha- cellulose cotton, this standard lab filter is not intended for ashing.APPLICATIONSscience : Routine qualitative analytical separations and liquid clarification in labsfood : Solid foodstuffs separation and liquid extraction, fat content determinationbeverage : Analysis and filtration of dense liquids like fruit pulps, musts, syrups, oil or plant extractsagriculture : Soil analysis and seed testingenvironment : Medium particles collection for pollution monitoring (stain intensity)education : Basic qualitative separations teaching and paper chromatographyMEDIUM RETENTION Retains medium-fine crystalline precipitates like:Sulfates (Pb, coarse form of Ba and Ca)Carbonates (Ba, Ca)Phosphates (Al, Pb, Struvite)Chromates (Fe, As, Pb)Ca Oxalate (hot), Pb Oxidepaper : pure cotton celluloseflow : mediumretention : 10~15 μm (medium)speed : 30~35 s (10ml DIN 53137)size : ⌀ 150 mmthickness : 150 μmweight : 86 g/m²ash : 0.1%qty : 50 discsPRE-FOLDED These Quadrant Folded Filters saves folding time when filtration is done repetitively. Use our pleating equivalent ST001-150v for even faster filtration. Suitable for gravity filtration in standard funnels, not vacuum.EQUIVALENCE & SIZE See the cross-reference table and size diagrams in the photos to choose the appropriate reference and diameter of your circles.
