Cell Counting Chamber Neubauer Hemacytometer Marien Field Glassware

Description

Product Overview

The Marien Field Cell Counting Chamber Improved Neubauer Hemacytometer is a precision‑engineered laboratory instrument designed for accurate enumeration of cells, microorganisms, and particles in a variety of research and clinical applications. Crafted from high‑quality optical glass, the chamber offers exceptional clarity and resistance to chemical exposure, ensuring long‑term durability even under frequent cleaning cycles. The standard footprint of 76 mm × 26 mm fits comfortably into most microscope stages, while the recessed counting grid provides a consistent depth of 0.1 mm, delivering reliable volume calculations across a wide range of sample concentrations.

Each chamber features the classic Neubauer grid pattern, consisting of 25 large squares subdivided into 16 smaller squares, allowing users to perform counts using either the 1 mm² or 0.25 mm² reference areas. The etched lines are laser‑sharp, eliminating ambiguity and reducing the learning curve for new technicians. The glass surface is chemically inert, tolerating ethanol, methanol, and a variety of staining solutions without clouding or etching, which preserves optical fidelity over years of use.

Marien Field has incorporated a patented anti‑reflective coating on the upper surface of the chamber, minimizing glare and enhancing contrast when viewing under brightfield illumination. This feature, combined with the high‑precision machining of the chamber’s edges, ensures that the sample remains evenly distributed across the counting area, preventing edge effects that can skew results. The chamber is supplied with a protective cap and a reusable cleaning brush, facilitating quick turnaround between experiments while maintaining sterility.

Designed for both academic and industrial environments, the hemacytometer meets ISO 9001 quality standards and is manufactured in Germany under strict quality‑control protocols. The product is not discontinued by the manufacturer, and it has maintained a steady presence in the market since its first availability on December 21 2015. Its best‑seller rank of #65 in Lab Cellware Chambers reflects its reputation for reliability among researchers who demand precise, repeatable measurements.

Overall, the Marien Field Improved Neubauer Hemacytometer combines classic design with modern enhancements, offering a cost‑effective solution for laboratories that require high‑throughput cell counting without compromising accuracy. Whether you are quantifying bacterial colonies, assessing cell viability, or performing particle size analysis, this chamber provides the foundation for trustworthy data collection.

Usage

The hemacytometer is ideally suited for a broad spectrum of applications, ranging from microbiology and cytology to environmental monitoring and bioprocess development. In microbiology labs, it enables rapid enumeration of bacterial or yeast cultures, supporting tasks such as inoculum preparation, growth curve analysis, and antimicrobial susceptibility testing. Cytologists rely on the chamber to assess cell density in blood, tissue culture, and cerebrospinal fluid samples, facilitating accurate diagnosis and treatment monitoring.

In addition to traditional brightfield microscopy, the chamber performs well under phase‑contrast and differential interference contrast (DIC) illumination, allowing users to distinguish live versus dead cells when combined with appropriate viability stains. The durable glass construction tolerates repeated exposure to fixatives, dyes, and solvents, making it compatible with protocols that involve methanol fixation, Giemsa staining, or fluorescent labeling.

For quality‑control laboratories in pharmaceutical manufacturing, the hemacytometer provides a reliable method for monitoring cell‑based production processes, ensuring that bioreactor yields meet predefined specifications. Environmental scientists use the device to count plankton, algae, or particulate matter in water samples, supporting ecological assessments and regulatory compliance.

Because the counting grid is standardized, the chamber integrates seamlessly with automated image analysis software, enabling high‑throughput data acquisition when paired with motorized microscopes. The product’s ergonomic design, including a smooth glass surface and a secure cap, reduces the risk of sample spillage and protects users from accidental exposure to hazardous reagents.

Regardless of the specific application, the Marien Field hemacytometer delivers consistent, reproducible results when proper loading techniques are followed. Users are encouraged to practice uniform sample distribution, avoid air bubbles, and calibrate their microscopes regularly to maintain optimal performance.

FAQ

How do I properly load a sample into the hemacytometer?

Begin by cleaning the chamber with distilled water and allowing it to dry. Place a small drop of the sample on the edge of the cover slip, then gently lower the cover slip so the liquid fills the counting grid by capillary action. Avoid introducing air bubbles, and ensure the grid is completely covered before counting.

Can the chamber be used with fluorescent stains?

Yes, the glass material is compatible with most fluorescent dyes. When using fluorescence, select an appropriate filter set on your microscope and follow the stain manufacturer’s protocol. The anti‑reflective coating helps minimize background fluorescence, improving signal clarity.

What cleaning procedures are recommended after each use?

Rinse the chamber with distilled water to remove residual sample. For stubborn residues, a brief soak in 70 % ethanol followed by a thorough water rinse is effective. Dry the chamber with lint‑free tissue or air‑dry before storing it with the protective cap.

Is the hemacytometer calibrated for different cell sizes?

The standard Neubauer grid is calibrated for a depth of 0.1 mm, which works well for most eukaryotic and prokaryotic cells. For unusually large or small particles, you may need to adjust the counting method or use alternative reference areas within the grid to maintain accuracy.

How does the anti‑reflective coating improve counting accuracy?

The coating reduces surface reflections that can obscure the grid lines and sample details. By minimizing glare, it enhances contrast between cells and the background, allowing for more precise identification and counting, especially under low‑light conditions.
