The quantitative or ashless filter papers are made with 100% high quality cotton linter fibres, which go through a severe chemical process. They have been washed out with a specific acid treatment and finally cleaned from impurities with demineralised water. This process allows reaching an ash content below 0.01%. Equivalent to Whatman grade 40, recommended for medium filtration.
