About ZENpore ST001

GRADE 1 STANDARD Qualitative Filter Paper Equivalent to Whatman grade 1, this laboratory 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. APPLICATIONS science : Routine qualitative analytical separations and liquid clarification in labs food : Solid foodstuffs separation and liquid extraction, fat content determination beverage : Analysis and filtration of dense liquids like fruit pulps, musts, syrups, oil or plant extracts agriculture : Soil analysis and seed testing environment : Medium particles collection for pollution monitoring (stain intensity) education : Basic qualitative separations teaching and paper chromatography MEDIUM 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 Oxide paper : pure cotton cellulose flow : medium retention : 10~15 μm (medium) speed : 30~35 s (10ml DIN 53137) size : ⌀ 185 mm thickness : 150 μm weight : 86 g/m² ash : 0.1% qty : 100 discs PLAIN-DISCS These Flat Discs are suitable for gravity and Buchner low suction vacuum filtration. The same affordable filters are also available funnel-ready as ST001-185q (folding) or ST001-185v (pleating).
