Sedgewick-Rafter Counting Cells, Brass, 1.0 ml

A simple design of surprising accuracy commonly used for counting larger plankton. Recommended for its ease of use and reproducible data. Intended for use with either a standard or inverted compound microscope at low magnifications, it limits magnification to about 200 x, which makes it unsuited to examining nannoplankton.

Sedgewick-Rafter cover glass sold in a pack of twelve units.
