This paper also allows faster color recognition and recovery. Whatman No. 40 Ashless Quantitative Filter Paper is pure cellulose based and does not contain any lignin, which diminishes the paper's filtration efficiency. Whatman No. 40 Quantitative Ashless Filter Paper resists cockle mud and stains and releases gases on heating to a greater extent than conventional Whatman Grade No. 40 qualitative filter papers.
