12.5 cm Quadrant-Folded Filter Paper, Pre-Folded disks, Qualitative Grade 2 - ZENPORE Slow Flow 125 mm (50 discs)
GRADE 2 Q QUADRANT Qualitative Filter Paper Equivalent to Whatman grade 2 FF, 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 RETENTION Retains fine crystalline and organic precipitates around 8?m 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 ?m (fine)speed : 40~45 s (10ml DIN 53137)size : ? 125 mmthickness : 160 ?mweight : 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 ST002-125v 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.
