Fristaden Lab Neubauer Hemocytometer – Diamond Etched, Light Glass

Description

Product Overview

The Fristaden Lab Improved Neubauer Hemocytometer is engineered for scientists who demand precision and reliability in cell quantification. Crafted from premium 3.3 borosilicate glass, the chamber provides exceptional chemical resistance and thermal stability, ensuring consistent performance across a wide range of laboratory conditions. The double‑improved Neubauer ruling is diamond‑etched, delivering a pattern of 1/400 mm² that meets stringent scientific standards and facilitates accurate enumeration of cells, bacteria, and particles. High‑light transmission glass, combined with an H‑shaped moat, maximizes optical clarity, allowing users to observe specimens with minimal distortion under both bright‑field and phase‑contrast microscopy. Each counting chamber holds a calibrated volume of 0.1 µL, and the device includes two 20 × 26 mm cover slips that sit precisely 0.100 mm above the chambers, guaranteeing reproducible results. The compact dimensions (2.95 × 0.39 × 1.38 in) and lightweight design (1.45 oz) make it easy to store and transport while maintaining the robustness required for daily laboratory use.

Usage

Designed for a broad spectrum of applications, this hemocytometer excels in microbiology, hematology, cell culture, and environmental testing. Researchers can employ it for counting blood cells, yeast, bacteria, algae, and even nanoparticle suspensions, making it a versatile tool in clinical diagnostics, pharmaceutical development, and academic research. The high‑transmission glass enables clear visualization of both stained and unstained samples, supporting techniques such as trypan blue exclusion, hemoglobin measurement, and fluorescence microscopy. Its ergonomic layout, featuring an H‑shaped moat that separates the two chambers, reduces the risk of cross‑contamination and simplifies sample loading. The included cover slips protect the sample from evaporation and provide a uniform optical path, essential for reproducible measurements. Whether used in a high‑throughput core facility or a teaching laboratory, the hemocytometer’s straightforward design shortens setup time, allowing scientists to focus on data acquisition and analysis.

FAQ

What is the purpose of the diamond‑etched ruling?

The diamond‑etched ruling creates a precise grid of 1/400 mm² squares, allowing accurate calculation of cell concentration by counting cells within a defined area. This level of precision meets international laboratory standards for cell counting.

Can I use this hemocytometer with fluorescence microscopy?

Yes. The high‑light transmission glass is compatible with both bright‑field and fluorescence microscopy, providing clear optical access without significant background interference.

How do I ensure the correct volume of 0.1 µL is measured?

Place a 20 × 26 mm cover slip over the chamber; the cover slip sits 0.100 mm above the grid, creating a defined chamber depth. Load the sample carefully to fill the chamber without introducing bubbles, and the volume will be precisely 0.1 µL.

Is the hemocytometer reusable after cleaning?

Absolutely. The 3.3 borosilicate glass can be cleaned with standard laboratory detergents and distilled water. Avoid abrasive cleaners to preserve the diamond‑etched grid integrity.

What warranty or support does Fristaden Lab provide?

Fristaden Lab offers a one‑year limited warranty covering manufacturing defects, along with access to a knowledgeable support team that can assist with setup, calibration, and any technical questions you may have.
