Qualitative filter paper

Microlab Qualitative Filter paper 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.
