Assistent Neubauer-improved Counting Chamber, dark line
Order no.:40442002
Counting chamber, double ruling, without clamps, for export outside EU only

Improved Neubauer ruling
9 large squares of 1 mm² = 9 mm²
The central square of 1 mm² contains 25 groups of squares divided into 16 mini squares of 0.05 x 0.05 mm each.
Leucocytes counting: 4 corner squares like Neubauer
Erythrocytes counting: groups of squares are used
Triple marginal lines at all sides of the square groups distinguish this ruling from Neubauer.
The middle line is decisive for the counting.
