MS. 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 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.
MS. Qualitative filter paper can be divided into fast, medium speed and slow three categories when measured by filtering speed and separation performance. Also it has two types: square and round. Qualitative filter paper to a square is 60 W 60cm, 30 W 30cm and so on. Qualitative filter paper circle diameter is 7cm, 9cm, 11cm, 12.5cm, 15cm, 18cm, 22cm and so on.
