zenpore 11 cm laboratory filter paper, quality standard grade 1 - medium flow 110 mm (100 discs) 11cm diameter
zenpore 11 cm laboratory filter paper, qualitative standard grade 1 - medium flow 110 mm (100 discs)
GRADE 1 STANDARD qualitative filter paper This laboratory filter paper corresponds to Whatman Grade 1 and is often used in laboratories, in which you need to separate a solid or precipitate from the filtrate. This standard high alpha cellulose cotton laboratory filter is not intended for ashing.APPLICATIONSScience : Routine qualitative analytical separations and liquid clarification in laboratoriesFood : Solid food separation and liquid extraction, fat content determinationBeverages : Analysis and filtration of dense liquids such as fruit pulp, must, syrup, oil or plant extracts Medium particle collection for contamination monitoring (spot intensity) Formation: Basic qualitative separations and paper chromatography MEDIUM RETENTION Retains medium-fine crystalline precipitates such as: 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 cell uloseflow: medium retention: 10~15 µm (medium)speed: 30~35 s (10ml DIN 53137)size: ⌀ 110 mmThickness: 150 µmWeight: 86 g/ m²Ash: 0.1%Quantity: 100 discsPLAIN-DISCSThese flat discs are suitable for gravity and Büchner vacuum filtration with low suction power. The same affordable filters are also available funnel-ready as ST001-110q (pleating) or ST001-110v (pleating).
