Hardened highly pure filter papers (approx. 0.05%) with extremely high chemical and mechanical resistance, especially recommended for vacuum and pressure filtration, and for the use of acidic and alkaline solutions.

  • High wet strength, easy to scrape off or wash off precipitates, no fibre release
  • High resistance to aggressive chemical components, like sulphuric and nitric acids (up to 40 % at 50 °C) and alkalis (up to 10 % at 20 °C).
