  • The viscose grade 2601, 20 g/² with a mean pore size of 100 µm is used for example for the testing of mortars according to DIN 18555-7.

 

  • The viscose grade 2601, 60 g/m² with a mean pore size of 75 µm is used in the petrochemical industry to retain the biggest particles before further analysis with a viscosimetry.

 

  • The viscose & polyester grade 2602, 150 g/m² is used in the food-processing industry for the detection of contaminants for example in dairy products & baby food.

Smooth Filter Papers for Qualitative & Technical Analyses

These filter papers are used for routine analyses like clarification, determination of substances, but also as discs with a center hole for technical applications. Grades with a wet burst resistance > 30 kPa are referred to as wet-strengthened and are therefore suitable for pressure or vacuum filtration. White and bright particles can be easily detected with the black paper grade 918, due to the color contrast for example for the detection of fluorine or silicon in water or the detection of mycelium in mildews.
