Alberts FilterQualitative 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 qualitative filter paper is chiefly used for qualitative chemical analysis and relevant filter separation, as well as manufacturing test paper of relevant purity. 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.
Widely used in general laboratory filtration: Used in conjunction with laboratory holders and funnels, or with paper cones and funnels.
Liquid clarifications, analytical separations.
Air and water analysis.
Rough sample preparation .
Better not to filter hot concentrated H₂SO₄ (Sulfuric acid) or HNO3 (Nitric acid ) solutions.
