    The quantitative filter papers or ashless filter papers are made with 100% high quality cotton linters fibers which go through a severe chemical process.

    They have been washed out with a specific acid treatment and finally cleaned from impurities with demineralized water. This process allows to reach an ash content of 0.01%. These papers are used to count during demanding analysis.
