Counting Chambers – Special Models for Quantitative Analysis

McMaster Counting Chamber, English Model (2 Fields)

Specifically designed for counting worm eggs in liquid samples or those preserved in media. With approximate dimensions of 75 × 32 mm, it features a cover glass with two 10 × 10 mm grids, each subdivided into ten rectangles. The distance between the chamber base and the cover glass is approximately 1.5 mm. The cover glass rests on three raised supports that define the analysis volume. Its main advantages are speed and low cost.
