Ashless Clippings, ashless filter aid

Ashless clippings

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.
