12.5 cm Lab Filter Paper, Standard Qualitative Grade 2 - ZENPORE Slow Flow 125 mm (100 Discs)
GRADE 2 STANDARD Qualitative Filter Paper Equivalent to Whatman grade 2, this laboratory filter paper is widely used for standard fine filtration when 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 : General filtration in the 8 ?m range, clarification of cloudy suspension in labsfood : Determination of total fat content in foodstuff and dairy, unsaponifiable fraction in fats and oils (fluted)beverage : Beer and malt analysis, removal of turbidity from wort and removal of yeast after fermentation (fluted)agriculture : Prefiltration of soil, hold nutrient in plant growth trialsenvironment : Air polution monitoring of specific atmospheric contaminants and black smokeHIGH RETENTIONRetains fine crystalline and organic precipitates around 8μm like:Metal Sulfides (Cd, Ni, Zn, Fe, Pb, Mn, Ag, As) Ba Sulfate, Pb Chromate, Mg oxideCa Oxalate (cold), Ca Fluoride, Pb Dioxidepaper : pure cotton celluloseflow : slowretention : 5~10 μm (fine)speed : 40~45 s (10ml DIN 53137)size : ⌀ 125 mmthickness : 160 μmweight : 86 g/m²ash : 0.1%qty : 100 discsPLAIN-DISCSThese Flat Discs are suitable for gravity and Buchner low suction vacuum filtration.The same affordable filters are also available funnel-ready as ST002-125q (folding) or ST002-125v (pleating).EQUIVALENCE & SIZESee the cross-reference table and size diagrams in the photos to choose the appropriate reference and diameter of your circles.
