Ashless Clippings, ashless filter aid
Whatman ashless filter aids enhance filtration speed by coagulating precipitates or
suspensions to form a thick retentive “prefilter” layer on top of normal filter paper.
Easily dispersible, the powder is of a purity similar to that of Whatman ashless quantitative papers.
It is supplied with a two-ended scoop for measuring 0.5 g or 2.5 g quantities.
