Triple dividing lines clearly delineate counting area for accurate and precise results. Molded from a single piece of thermal and shock resistant glass with a polished chamber and cover glass assuring precise capillary loading and even cell distribution. Fluid volume is 0.1 mm3/mm2 and 0.00025 mm2 per each square.
