The Marienfeld Cover Glasses (0.4 mm) are precision-engineered optical glasses designed for use with counting chambers and haemacytometers. They provide the accuracy needed in cell counting applications by forming a precise capillary gap that defines the volume of suspension above the counting grid.
With ground and polished edges, these cover glasses ensure safe handling and excellent fit on the outer bearing surfaces of counting chambers, adhering tightly to create a reliable measurement system. Their high optical quality also makes them ideal for blood smears and diagnostic microscopy.
Key Features
- Made of Special Optical Glass – Ensures excellent transparency and flatness for accurate cell counting.
- High Edge Quality – Perfectly suited for blood smears and microscopy applications.
- Ready for Use – Individually packed to guarantee cleanliness and prevent damage.
- Reliable Capillary Gap Formation – Adheres to haemacytometer bearing surfaces for consistent results.
- Certified Quality – CE-marked and compliant with EU Regulation 2017/746 (IVDR), with batch numbers for traceability.
Applications
- Use with haemacytometers and counting chambers for cell and blood counting.
- Preparation of blood smears and diagnostic microscopy.
- In vitro diagnostic workflows requiring precise optical components.
