Cell Counting Chamber Neubauer Hemacytometer Marienfeld 10pcs Box

Description

Product Overview

The Marienfeld Cell Counting Chamber Improved Neubauer Hemacytometer is a precision‑engineered glass slide designed for the accurate quantification of cells, microorganisms, and sub‑micron particles. Constructed from high‑quality optical glass, the chamber offers a uniform 0.1 mm depth that creates a consistent fluid layer, eliminating variability caused by uneven surfaces. The central counting area features a 3 × 3 mm grid divided into nine large squares, each further subdivided into sixteen medium squares, and a central region of 400 tiny squares (50 µm each) for counting very small particles. This hierarchical grid system enables users to select the appropriate counting scale for their sample, whether they are measuring blood cells, bacterial cultures, or cultured cell lines. The chamber dimensions conform to the standard Neubauer format, ensuring compatibility with most microscopes and counting software. Each box contains ten individually sealed chambers, providing a cost‑effective solution for laboratories that perform high‑throughput analyses. The product is manufactured by Marienfeld, a reputable brand known for rigorous quality control and compliance with international laboratory standards.

Usage

Designed for versatility, this hemacytometer is suitable for a broad spectrum of applications, including hematology, microbiology, cell culture, and environmental testing. Researchers can use the chamber to count red and white blood cells in clinical samples, assess bacterial density in fermentation processes, or evaluate cell proliferation in tissue engineering studies. The 0.1 mm depth ensures that the sample volume is precisely defined, which is critical for calculating concentrations per milliliter. Users simply load a measured drop of the specimen onto the chamber, cover it with a cover slip, and place it under a microscope at 10× objective for a clear view of the grid. The clear glass provides excellent optical clarity, reducing distortion and allowing accurate visualization of even the smallest particles. Because the chambers are individually sealed, they remain sterile until use, minimizing contamination risk. The product’s durability also makes it suitable for repeated cleaning with standard laboratory detergents, extending its service life in busy research environments.

FAQ

How do I prepare a sample for counting with this chamber?

Begin by mixing your cell suspension thoroughly to ensure an even distribution. Using a calibrated pipette, place a small drop (approximately 10 µL) onto the central counting area of the chamber. Gently lower the cover slip to spread the sample evenly across the grid without trapping air bubbles. Allow the sample to settle for a few seconds before placing the chamber on the microscope stage. For best results, use a 10× objective lens and focus on the grid lines to verify that the sample thickness matches the 0.1 mm depth.

Can the chamber be reused after cleaning?

Yes, the Marienfeld hemacytometer is designed for multiple uses. After each counting session, remove any remaining specimen and rinse the chamber with distilled water. For thorough cleaning, soak the chamber in a mild laboratory detergent solution for a few minutes, then rinse again with distilled water and allow it to air‑dry. Avoid using abrasive materials or harsh chemicals that could scratch the glass or alter the grid dimensions.

What is the accuracy of cell concentration measurements using this chamber?

When used correctly, the Neubauer design provides a high degree of accuracy, typically within ±5 % of the true concentration. The precision stems from the defined chamber depth and the exact area of the counting grid. Accuracy can be further improved by performing duplicate counts and averaging the results, as well as by calibrating the microscope’s eyepiece reticle if available.

Is this chamber compatible with automated counting systems?

The standard Neubauer dimensions are widely accepted by many automated cell counting platforms. While the chamber is primarily intended for manual microscopy, it can be integrated into certain image‑analysis software that recognizes the grid pattern. Verify compatibility with your specific instrument’s specifications, and consider using a compatible cover slip to maintain the required optical path.

What warranty or guarantee does Marienfeld provide?

Marienfeld offers a one‑year limited warranty covering manufacturing defects in the glass or grid markings. If a chamber arrives damaged or exhibits irregularities in the grid, contact our customer service team with the order details and a photo of the defect. We will arrange a replacement at no additional cost, ensuring uninterrupted workflow in your laboratory.
