HYDRO-BIOS: Counting Chamber for Zooplankton
Category: Plankton Observation Module
Art.No.: 435 01x
Keywords: Counting Chamber for Zooplankton, Counting Chamber
Supplier: Qingdao Watertools Technology?Co., Ltd.
Introduction:

Based on the Bogorov design the Counting Chambers for Zooplankton have been designed for easy enumeration of large amounts of zooplankton. A plexiglass block with precisely machined grooves and a polished bottom provides best possible transparency. Due to the small dimensions all chambers can be used with stereo microscopes. The standard models are manufactured with grooves in meander profile. The Ballast Water models, modified by Gollasch, are manufactured with grooves in line pattern, bisect line pattern and grid pattern. This very much alleviates the use of the chambers on moving vessels even under choppy sea conditions.
