Product description
Filter paper is a kind of paper with good filtration performance. The paper is loose and has strong absorption properties for liquid.
Natural filtration is generally used to separate liquids and solids by the ability of the filter paper and the retention of solid particles.
MS ashless quantitative are produced under carefully controlled conditions to ensure low ash levels with progressively increasing wet strengths. It is a classic, general purpose paper with fast, medium or slow speed and size in liquid retention. Typical applications include gravimetric analysis for components in cements, clays, iron and steel products; as a primary filter for separating solid matter from aqueous extracts in general soil analysis and Pure clean-up prior for AA spectrophotometry.
Qualitative filter paper can not be soluble in acid, alkali and other organic solvents impure substances, which is applicable to pharmaceutical, chemical plants producing all kinds of pharmaceutical and solvent filtration.
The good characterization of folded filter paper compared to the same type of filter paper formation has the advantage of speeding up the flow rate and increasing the load power.
