Allgemeine Beschreibung
- Savings in time required to quadrant-fold circles to fit conical filter funnels in repetitive or multiple analyses
- Decreased overall filtration time because of the extra surface area exposed; the normal slow down of filtration speed due to the loading of particulate is postponed
- Increased total loading capacity as more filter area is available
- Maintained flow rate due to the reduction in filter paper contact with funnel side and, the self-supporting shape of the filter itself
- The prepleating does not significantly affect any of the technical data and the same figures may be used for the flat circles
Grade 5V: 2.5 μm (slow filter paper)
The maximum degree of fine particle filtration in the qualitative range. Capable of retaining the finest participates encountered in chemical analysis. Slow flow rate. Excellent clarifying filter for cloudy suspensions and for water and soil analysis.
Leistungsmerkmale und Vorteile
- Has highest nominal particle retention efficiency of fine particles in Whatman qualitative cellulose paper range
- Slow filtration speed (Herzbergspeedof 1420 s)
- Fluted (pre-pleated) to facilitate use with conical filter funnels
- Fluted filter paper design decreases filtration time and increases loading capacity
