18.5 cm Fluted Filter Paper, Pre-Pleated (Folded), Qualitative Grade 1 - ZENPORE Medium Flow 185 mm (100 Discs)
Size:18.5 cm diameter GRADE 1 V FLUTED Qualitative Filter PaperEquivalent to Whatman grade 1 V, this pre-pleated 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 RETENTIONRetains 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 : ⌀ 185 mmthickness : 150 μmweight : 86 g/m²ash : 0.1%qty : 100 discsPRE-PLEATEDThese Prepleated Fluted Filters saves filtration and folding time thanks to their increased surface area and loading capacity.Provides faster flow than simple folding while maintaining similar grade characteristics.Suitable for gravity filtration in standard funnels, not vacuum.EQUIVALENCE & SIZESee the cross-reference table and size diagrams in the photos to choose the appropriate reference and diameter of your circles.
