Quantitative Analysis: General quantitative analysis and especially useful for gravimetric determinations of flocculent or gelatinous precipitates like iron hydroxides, zirconium, aluminum, and cobalt sulfide. It can also be used in atmospheric pollution control to determine gaseous compounds. Recommended for fast analytical procedures involving unstable precipitates such as silicon. Other applications include the analysis of bauxite, alkali metals in glazes or varnishes, and paper analysis.

Microclar filter papers are designed to meet the requirements of analytical, physico-chemical, and gravimetric filtration methods. They are manufactured in a strictly controlled environment to ensure uniformity and high purity. This line of filter papers is developed for use in techniques that allow the quantification of suspended particles in a liquid. They are ashless filter papers and exhibit high mechanical strength when wet. They are manufactured using reverse osmosis water and treated with diluted acids to eliminate any organic and inorganic impurities.

They are presented in boxes of 100 units.
