- 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
Cytiva Healthcare’s Life Sciences business offers a variety of Whatman brand qualitative filter papers. Wet-strengthened and standard grades are available.
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.
