ABSTRACT:
A pipet for slurry and the like comprising a body with an end chamber containing a slidable element which, between them, defines a predetermined volume. The element includes an end plate to close the chamber, and a biased plunger is mounted in the body for moving the element so as to open and close the chamber and thus trap the predetermined volume of material to be sampled. The element is replaceable with one of different size to vary the volume of sample. In one form, a cutting edge on the body and a cutting surface on the end plate cooperate to sever fibrous material only partly in the chamber.
