QUALITATIVE FILTER PAPERS

A widely used standard grade filter paper for routine applications with medium retention and flow rate.

Slightly more retentive than Grade 1 with a corresponding increase in filtration time (i.e., slightly slower filtration speed).

A standard grade filter used in qualitative analytical techniques to determine and identify materials. For use in büchner funnels.

Fast flow & retention of coarse precipitates

Slow flow & retention of coarse particles

Twice as fast as No.5 with similar retention)

General Application

Flow retention between No.1 & No.4)

Fast flow, Strong filter

Filter Paper, No. 113V, 30μm, Qualitative, Folded/Prepleated

General Application

Half thickness of No.113

Fastest flow, For coarse retention
