Achieve precise cell quantification with the Neubauer hemacytometer counting chamber designed for manual cell counting in hematology, research, and clinical laboratories. The LW Scientific CTL-HEMM-GLDR features improved Neubauer ruling with fused rhodium on glass, providing brightly illuminated grid lines for accurate erythrocyte and leukocyte enumeration. This Neubauer hemacytometer counting chamber is the gold standard for blood cell counting, cell culture analysis, and viability assessment across medical, veterinary, and research applications.

Precision Neubauer Hemacytometer Counting Chamber

The Neubauer hemacytometer counting chamber features double rulings visible through a wide range of illumination conditions. The improved Neubauer pattern is precision-etched 0.1mm below the cover glass, creating a defined counting volume essential for accurate cell concentration calculations. Fused rhodium coating on the glass surface provides distinct, brightly illuminated grid lines that remain clearly visible under low-contrast microscopy conditions.

The H-shaped moat design offers two independent counting areas, enabling duplicate counts for statistical reliability. Light transmission between 29% and 32% ensures optimal visualization of cells and grid lines.

High-Quality Optical Glass Construction

Crafted from high-quality optical glass, this Neubauer hemacytometer counting chamber delivers superior clarity for detailed cell visualization. The precision-ground surface ensures even depth across the counting area, critical for accurate volume calculations. Each grid square in the improved Neubauer pattern has specific dimensions, with the 3×3mm counting grid subdivided into nine 1×1mm squares for versatile cell counting applications.

The reusable design withstands repeated cleaning with 70% ethanol, providing long-term value for laboratories. Additionally, two special counting chamber cover glasses are included, precisely manufactured to maintain the 0.1mm chamber depth.

Versatile Applications Across Disciplines

This Neubauer hemacytometer counting chamber serves diverse laboratory applications. In hematology labs, it enables manual differential counts of erythrocytes and leukocytes for blood analysis. Research laboratories use it for cell culture concentration determination, ensuring optimal seeding densities for experiments.

Fertility clinics rely on the Neubauer hemacytometer counting chamber for sperm counting and motility assessment. Microbiology laboratories utilize it for bacterial, yeast, and fungal enumeration. The device also supports cell viability assessment when combined with trypan blue or other exclusion dyes.

Manual Cell Counting Gold Standard

The Neubauer hemacytometer counting chamber remains the reference standard for validating automated cell counters. Researchers rely on manual counting with hemacytometers when automated systems encounter atypical cell morphologies or low cell concentrations. The defined grid geometry enables precise cell concentration calculations using the formula: cells/mL = (average count × dilution factor × 10⁴) / number of squares counted.

The dual-chamber format allows technicians to perform two independent counts per sample without cleaning, improving workflow efficiency. Furthermore, the improved Neubauer ruling accommodates various cell sizes through its subdivided grid structure.
