MARIENFIELD Counting chamber, bright lined, Imp. Neubauer 0.1 mm depth

The Marienfeld Superior Improved Neubauer Counting Chamber is a highly precise instrument designed for accurate particle counting in liquids, including cells in suspension. It is widely used in hematology, microbiology, and cell culture applications to determine cell concentration and perform quantitative analyses.

Key Features

1. High-Quality Materials
   • Made from special optical glass for enhanced durability and precision.
   • Designed to comply with DIN 12847 standards.
2. Precision Manufacturing
   • Depth tolerance of the chamber is strictly maintained with a maximum deviation of 2%.
   • Each chamber is individually tested and calibrated according to the German Calibration Ordinance to ensure accuracy.
3. Dual Grid System
   • Equipped with two sets of grids for duplicate determinations, essential for In Vitro Diagnostic (IVD) applications.
   • Provides a double-check mechanism for improved accuracy in cell counting.
4. Grid Design
   • Central stage with ground and polished surfaces for accurate volume control.
   • Chamber depth of 0.1 mm, suitable for standardized cell suspension analysis.
5. Cover Glass
   • Supplied with two hemacytometer cover glasses (20 x 26 mm) for optimal precision.
   • Cover glasses have a thickness of 0.4 mm to maintain capillary force balance, ensuring even distribution of liquid over the grids.
6. Line Types
   • Dark Line Grids: Standard grids with dark lines for visibility under the microscope.
   • Bright Line Grids: Thin, transparent metallic coatings on grids with a dark metallic background, improving contrast for easier evaluation of cell suspensions.
7. Packaging
   • Individually packed in a transparent plastic box for protection.
   • Comes in cartons containing 10 chambers.
8. Compatibility
   • Suitable for use with specific coverslip sizes depending on the grid type:
     • Fuchs-Rosenthal: 24 x 24 mm coverslip.
     • Nageotte: 30 x 30 mm coverslip.
