These filter papers are qualified for food control according to LFBG paragraph 64, beverage analysis and environmental monitoring.Measured with 100 mm water column instead of 50 mm.

Filter papers in a flat, quadrant folded format to fit conical filter funnels. Easy and time-saving handling for analyses with high sample throughput.

Filter papers in a flat, pyramidal folded format. Easy and time-saving handling.

Made from 100 % cellulose. Filtration speed according to DIN 53137. Capacity of separation according to DIN 53135.Pore size 12 to 15 µm.

Filters are impregnated with silicon and are suitable for separating water and organic solvents. The aqueous phase is retained, but the solvent can flow through.

Other diameters / formats are available on request.

Circles and sheets. Qualitative. The most widely used grade of filter paper.
