Description
Product Overview
The CTL-HEMM-GLDR hemacytometer is a precision‑engineered cell counting chamber designed for laboratories that require reliable quantification of erythrocytes, leukocytes, and other microscopic particles. Manufactured by Thomas Scientific, a trusted name in scientific equipment, this chamber incorporates the classic Neubauer grid with 0.1 mm depth markings, ensuring that each counted cell falls within a defined volume for accurate concentration calculations. The device features an H‑shaped moat that creates two separate counting areas, allowing double‑counting for increased statistical confidence. Constructed from high‑quality borosilicate glass, the chamber offers excellent optical clarity, resistance to chemical exposure, and long‑term durability. Its dimensions of 8 × 8 × 2.5 inches and lightweight design (1.6 oz) make it easy to handle, store, and integrate into existing microscope setups. The product is not discontinued, and it has been available since February 27 2010, reflecting a proven track record in cell analysis applications.
Usage
This hemacytometer is ideal for a wide range of laboratory environments, including clinical diagnostics, research institutions, pharmaceutical quality control, and educational settings. It is particularly suited for tasks such as blood cell counting, microbial enumeration, and particle size distribution studies. Users can place a small volume of diluted sample onto the chamber, cover it with a standard cover glass, and view the grid under a microscope at 10× objective magnification. The double‑counting feature enables the user to perform two independent counts within the same slide, reducing variability and improving reproducibility. The device is compatible with most upright and inverted microscopes, and its standard dimensions allow seamless integration with existing slide holders and stage clips. Routine cleaning with distilled water and gentle drying ensures the chamber remains free of residues, preserving optical performance over many years of use.

FAQ
How do I prepare a sample for counting with this hemacytometer?
Begin by diluting your sample in an appropriate isotonic solution, typically using a 1:200 dilution for blood cells. Mix gently, then load 10 µL of the diluted sample into the chamber’s central well, ensuring the liquid spreads evenly across the grid. Place a cover glass on top, avoid air bubbles, and allow the sample to settle for a few seconds before counting.
Can this chamber be used for counting microorganisms?
Yes, the CTL-HEMM-GLDR is suitable for counting bacteria, yeast, and other microorganisms when the appropriate staining or dilution protocol is applied. The fine grid and depth markings enable accurate enumeration of small particles, making it a versatile tool for microbiology labs.
What cleaning procedures are recommended to maintain accuracy?
After each use, rinse the chamber with distilled water to remove residual sample. Gently wipe the surface with a lint‑free cloth or tissue, avoiding abrasive materials that could scratch the glass. For stubborn residues, a mild detergent solution can be used, followed by thorough rinsing and drying. Store the chamber in a protective case to prevent damage.
Is the hemacytometer compatible with all microscope types?
The chamber conforms to standard slide dimensions, making it compatible with most upright, inverted, and phase‑contrast microscopes. Ensure your microscope’s stage can accommodate the 8 × 8 mm footprint, and use a 10× objective for optimal grid visibility.
What warranty and support does Thomas Scientific provide?
Thomas Scientific offers a limited warranty covering manufacturing defects and provides access to technical support resources, including online manuals, video tutorials, and direct assistance from trained specialists. Replacement parts are available upon request, ensuring minimal downtime for your laboratory.
