The Improved Neubauer Counting Chamber is designed for manual counting of cells and suspended particles in biological samples such as blood, urine and cell cultures using bright-field optical microscopy. It is a 0.1 mm depth cell counting chamber manufactured from homogeneous and isotropic optical glass, featuring two independent counting areas with engraved central grids that define a known volume for cell concentration calculation. The improved grid pattern allows more detailed counting and improved precision. It is a manual counting method and depends on proper sample preparation and correct use of dedicated cover glasses to ensure nominal depth.

FAQ
-
Q: What is the difference between standard and improved Neubauer chambers?
A: The improved version includes additional grid subdivisions, allowing more detailed counting and improved concentration calculations.
-
Q: Can it be used for red and white blood cell counting?
A: Yes. It is suitable for manual blood cell counting when proper laboratory procedures are followed.
-
Q: Does it replace automated cell counters?
A: No. It is a manual microscopic counting method dependent on operator technique.
-
Q: Are specific cover glasses required?
A: Yes. The 0.1 mm depth is ensured only when using dedicated Neubauer cover glasses.
-
Q: Can it be used for non-biological particles?
A: Yes. It may be used for counting suspended particles compatible with optical microscopy.
