Description
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
Fluted filter for capturing gelatinous precipitate
Whatman Grade 4V prepleated (fluted) filter paper from Cytiva is frequently used to filter gelatinous precipitate or during general filtration that does not require the collection of fine particles. The filter sheets are also useful for rapid filtration of biological fluids or organic extracts prior to analysis.
