The C-chip™ is an easy-to-use, precision disposable plastic haemocytometer, developed to solve the problem of conventional glass haemocytometers. Supplied individually packed, in a box of 50 slides, these Neubauer Improved type haemocytometers have 0.1 mm 0.05 mm grids, for counting blood cells (erythrocytes, leukocytes), mammalian cells etc. Supplied as box of 50 double chamber slides (100 tests). Features and benefits: • No need to coverslip • No need to wash for reuse • No more contact to hazardous materials • Accurate, reliable and repeatable • Bright grid pattern • tests per slide • Pack of 50 double chamber slides (= 100 tests) • Quartz grade optical plastic • Sturdy and strong Main applications: • Blood analysis • Cell culture; cell concentration measurement and cell viability counts • Microbiology; bacterial and fungal spores Dimensions: 25 75 1.6 mm (w l t) Chamber depth: 100 µm Chamber volume 10 µL

These Bright-Line (Rhodium coated) glass Haemacytometers are designed for accurate counting of cells in blood or other fluids, with one-piece glass construction, an H-shaped moat to form two counting areas (plateaus) and ""V"" slash at the loading side of each plateau. Each plateau features enhanced Neubauer rulings, the ruled surface being 0.1 mm below the cover glass, limiting the volume of blood or fluid over square mm to 0.1 cu.mm and over each of 400 squares (within the central square mm) to 0.00025 cu. mm. Contact of the flat, polished cover glass surfaces with cover glass supports produces an exact volume of fluid over the counting area. The difference in surface tension characteristics between the metallic surface on the chamber and the polished cover glass assures smooth capillarity for precise loading and more even cell distribution. Supplied as double chamber with two cover glasses or kit which includes double counting chamber, cover glasses and red and white pipettes, all in protective case. Spare/replacement glass cover glasses are also available, as pack of 2. • Bright Line (Rhodium coated) counting chamber • Improved Neubauer ruling pattern • Cell Depth: 0.100 mm ±2 • Volume: 0.1 µL To clean the counting chamber after use: remove the cover glass and clean with water or mild cleaning solution (e.g. 10% bleach solution). Dry the counting chamber with soft cloth/wipe, or rinse with acetone.
