Grade 4V, folded filter, circle 32cm 100/pack

Cytiva's Whatman Grade 4V filter paper is well suited for qualitative analysis or general filtration of coarse particles. The fluted filter design increases filtration speed, flow rate, and loading capacity.

Very fast flow rate
Retention of coarse and gelatinous precipitates
Nominal particle retention rating of 20–25 µm
Fast filtration speed (Herzberg 37 s)
Fluted (pre-pleated) for compatibility with conical filter funnels without the need for further folding
