Description
The Neubauer hemacytometer (haemacytometer) is used to count blood cells and algae under a compound microscope. It is a counting chamber with 2 counting grids.
What is the difference between a standard and bright-line Neubauer hemacytometer?
The main difference between a standard Neubauer hemacytometer and a bright-line Neubauer hemacytometer lies in their grid visibility:
Standard Neubauer hemacytometer:
Has etched grid lines on the glass surface
Grid lines can be somewhat difficult to see, especially under lower magnifications
Requires more careful focusing and lighting adjustments to clearly visualize the grid
Bright-line Neubauer hemacytometer:
Has grid lines that are filled with a reflective material (usually silver or aluminum)
Grid lines appear brighter and more distinct, especially under phase contrast microscopy
Easier to visualize the grid, particularly at lower magnifications
Improves accuracy and reduces eye strain during cell counting
Both types have the same grid pattern and chamber depth, so the calculation methods remain the same. The bright-line version simply offers improved visibility, which can lead to more accurate and efficient cell counting, especially for users who perform frequent counts or those who are less experienced with using hemacytometers.
