Ashless Quantitative Filter papers Ashless filters (approx. 0.007%), recommended for quantitative analysis.

For routine gravimetric analysis and the preparation of samples for instrumental analysis requires high purity. Our filter papers are being washed out with acid to meet this critical requirement. Our quantitative filter papers are available in two types – ashless and ashless hardened. Our ashless grades are made of 100% cotton linters with an ash content of 0.007% The ashless hardened grades are made of pure cellulose with an alpha cellulose content of almost 100%
