Sedgewick-Rafter Counting Cells, Brass, 1.0mL

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.

Specifications:
• 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")

EKMANN GRAB 6" X 6" X 6"

This is the grab to choose for soft, finely divided littoral bottoms that are free from vegetation, such as sticks and decayed leaves (or with short, erect vegetation only) as well as intermixtures of sand, stones and other coarse debris. The specialized function of this dredge is the taking of quantitative and qualitative samples of macroscopic bottom fauna to determine the productivity of soft bottoms, particularly those composed of finely divided muck, mud, ooze, submerged marl and fine peaty materials. Versatile and durable, it is suited for preliminary as well as more precise observation. It is not recommended for rocky or sandy bottoms or moderate macrophyte growth because small pebbles or macrophyte stems prevent proper jaw closure.
