Counting chambers
Counting chamber, Improved Neubauer, bright line
Bright line. With double ruling. Calibratable. Same counting grid as the Improved Neubauer cell, but with rhodium coated chamber base. Rulings are engraved into the Rhodium layer and appear bright under normal microscope settings. By altering the contrast it is possible to reverse the image under the microscope to make the rulings appear brighter or darker as required....
Counting Chamber, Malassez
BLAUBRAND ®. Double ruling. Without snap-on clips. Cell depth 0.2 mm. The ruling is rectangular, covering an area of 5 mm 2. The large rectangles measure 0.25 x 0.20 = 0.05 mm 2. They are each subdivided into 20 mini squares with an area of 0.0025 mm 2. This chamber is commonly used for counting cells in the cerebrospinal fluid, or for counting nematodes....

Counting chambers, Fuchs-Rosenthal ruling, bright line
Bright lined, double net ruling, includes 2 haemocytometer glass covers, with LOT number on the packaging, labelled with: usable until, CE pursuant to IVD 98/79 EC. Grid has 16 x large 1 mm² squares. Each square is divided into 16 smaller squares each with a side length of 0.25 mm and an area of 0.0625 mm². These counting chambers are commonly used to count cells in cerebrospinal fluid....
Counting chambers, Thoma ruling, bright line
Bright lined, double net ruling, includes 2 haemocytometer glass covers, with LOT number on the packaging, labelled with: usable until, CE pursuant to IVD 98/79 EC. Grid is the same as the grid in the centre of large square in the Neubauer chamber. The area of the small square is 0.0025 mm². Since the large outer squares are not included, the Thoma system is only used to count thrombocytes and erythrocytes....
