Filtech Qualitative High Wet Strength Filter Paper ;
- Used when application is in a system under pressure or vacuum requiring the use of high wet strength grades.
- These grades contain a small amount of chemically stable, insoluble binding resin which strengthens the natural fibre to fibre bonds under wet conditions.
- Grades containing wood fibre or resins are not recommended for use in quantitative ashing techniques or in Kjeldahl estimations.
