About Qualitative Filter Paper 18.5 Cm Quadrant Folded
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. APPLICATIONS science : General filtration in the 8 ?m range, clarification of cloudy suspension in labs food : 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 trials environment : Air polution monitoring of specific atmospheric contaminants and black smoke HIGH RETENTION Retains fine crystalline and organic precipitates around 8μm like: Metal Sulfides (Cd, Ni, Zn, Fe, Pb, Mn, Ag, As) Ba Sulfate, Pb Chromate, Mg oxide Ca Oxalate (cold), Ca Fluoride, Pb Dioxide paper : pure cotton cellulose flow : slow retention : 5~10 μm (fine) speed : 40~45 s (10ml DIN 53137) size : ⌀ 185 mm thickness : 160 μm weight : 86 g/m² ash : 0.1% qty : 50 discs PRE-FOLDED These Quadrant Folded Filters saves folding time when filtration is done repetitively. Use our pleating equivalent ST002-185v for even faster filtration. Suitable for gravity filtration in standard funnels, not vacuum.
