The Gridded Sedgewick Rafter is now available! 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.
Frame: brass, mounted on 1" x 3" glass slide.
Cell size: 50 mm x 20 mm x 1 mm (1.968" x 0.787" x 0.04")
Cell volume: 1.0 mL
Includes: 2 cover glasses, plastic case.
