Description & Specifications


Grade 113V
Diameter (Metric) 50cm
Particle Retention >30μm
For Use With (Application) Use for coarse particles and gelatinous precipitates.
Format Circle
Porosity Coarse

Very thick and strong filter with creped surface for extremely high loading capacity, particularly in folded form.

  • 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 — highly suitable for coarse particles and gelatinous precipitates
  • Fastest flow rate of any qualitative grade — flow rate maintained due to the reduction in filter paper contact with funnel side and the self-supporting shape of the filter itself
  • Prepleating does not significantly affect any of the technical data, and the same figures may be used for the flat circles

  • Typical thickness: 420μ
  • Basis Weight: 125g/m2
  • Material: Cellulose
  • Alpha Cellulose Content, Min.: 0.98%
