The range of Whatman filtration aids are available in three forms and pack sizes.

ASLESS POWDER - Cellulose powder with an ash content of 0.015% and suitable for use as a filter bed

ASHLESS FLOC - Bulky mass of dry dispersed cellulose fibres which assist coagulation by forming a more flocculent suspension.  Ash content is 0.015% by weight.

ASHLESS CLIPPINGS - These are offcuts for maceration to make a pure filter pulp, which settles under suction in a funnel to form a thick, highly retentive filter bed.
