General description

Manufactured according to DIN 12 847, including 2 haemacytometer cover glasses.The ruling shows 9 large squares of 1 mm² each.The four large squares in the corners marked "L" for counting leucocytes are each subdivided into 16 squares with 0.25 mm sides.The large square in the center is subdivided into 16 squares with 0.25 mm sides.The large square in the center is subdivided into 25 group squares of 0.2 mm sides.

  • Same ruling as improved Neubauer, but with rhodium coated chamber bottom.
  • Rulings are engraved into the rhodium layer and appear bright under normal microscope settings.
  • By altering the contrast, the microscope image can be reversed, so that the rulings appear brighter or darker, as required.
