About Filter Paper 15 Cm Cone-Folded Filter
GRADE 4 P PYRAMID Qualitative Filter Paper Equivalent to Whatman grade 4 FF, this very fast laboratory filter paper is used for coarse 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 : Routine clean-up of insoluble liquids such as biological fluids or organic extracts in labs food : Determination Sodium Chloride in foodstuffs beverage : Filtration of musts in wine metalurgy : Determination of silicon impurities in pig iron and steel environment : Fast flowing air and exhausts monitoring when the collection of fine particles is not critical. COARSE RETENTION Retains coarse particles and gelatinous precipitates like: Metal hydroxides (Al, Cr, Fe, Mg) , Be Oxide Insoluble iron and ore, precipitated Silicates Culture media, and colloidal sediments paper : pure cotton cellulose flow : fast retention : 20~25 μm (coarse) speed : 15~20 s (10ml DIN 53137) size : ⌀ 150 mm thickness : 140 μm weight : 86 g/m² ash : 0.1% qty : 200 discs CONE-STACKED These Pyramid Folded Cones comes already stacked and saves folding time when filtration is done repetitively. Use our pleating equivalent ST004-150v for even faster filtration. Suitable for gravity filtration in standard funnels, not vacuum.
