Minipore quantitative filters are designed for gravimetric analysis and the preparation of samples for instrumental analysis.
Grade : 40M
The classic general purpose ashless filter paper with medium speed and retention. Typical applications include gravimetric analysis for numerous components in cements, clays, iron and steel products, as a primary filter for separating solid matter from aqueous extracts in general soil analysis
Grade : 41M
The fastest ashless filter paper, recommended for analytical procedures involving coarse particles or gelatinous precipitates (e.g.iron or aluminum hydroxides). Also used in quantitative air pollution analysis as a paper tape for impregnation when determininggaseous compounds at high flow rates
Grade : 42M
A world standard for critical gravimetric analysis with the finest particle retention. Typical analysis precipitates include bariumsulfate, metastannic acid and finely precipitated calcium carbonate.
Features
