Double ruling. Without snap-on clips. Calibratable. Cell depth 0.1mm. Grid is the same as the grid in the centre of large square in the Neubauer chamber. The area of the small square is 0.0025mm². Since the large outer squares are not included, the Thoma system is only used to count thrombocytes and erythrocytes....

With double ruling. Calibratable.
Cell depth 0.1mm. Counting grid with 9 large squares each 1 mm². The 4 large squares in the corners for counting leucocytes are each subdivided into 16 squares with a side length of 0.25mm. The large square in the middle is subdivided into 25 squares each with a side length of 0.2mm. Each of these is further subdivided into 16 smaller squares each with a side length of 0.05 mm and an area of 0.0025mm². The 5 group squares marked with an 'E' are used to count thrombocytes and erythrocytes. All group squares have triple boundary lines on each side....

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....

With double ruling. Calibratable. Cell depth 0.1 mm. Same ruling as Improved Neubauer, but the large square in the centre is divided into 16 squares each with a side length of 0.25 mm. Unlike the more modern Improved Neubauer counting chambers, the counting area of each group square is limited by the outermost of the triple border lines....

BLAUBRAND ^®. Double ruling. With or without snap-on clips. Cell depth 0.2 mm. The ruling differs from the customary systems for blood cell counts by its large area of 16 mm ². The ruling shows 16 large squares of 1 mm ². Each large square is subdivided into 16 mini squares with 0.25 mm sides and an area of 0.0625 mm...

BLAUBRAND ^®. Double ruling. With or without snap-on clips. Cell depth 0.1mm. The ruling shows 9 large squares of 1 mm ² each. These are used for counting leucocytes. Each large square is subdivided by double lines (0.05 mm apart) into 16 group squares with 0.2 mm sides. The group squares correspond in size to the Neubauer counting chamber, but have no further subdivisions. They are used for counting thrombocytes and erythrocytes. The double lines form mini squares with an area of 0.0025 mm...

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.
