Digital Refractometer for Urine, Serum Protein, and Refractive Index Measurement

This digital refractometer is engineered for precise clinical analysis, measuring urine specific gravity, serum protein concentration, and refractive index with high accuracy. It features:

• Urine Specific Gravity Range: 1.000–1.050 with a minimum division of 0.001 and ±0.002 accuracy, critical for renal function assessment in clinical diagnostics.
• Serum Protein Concentration Range: 0.12 g/dL with 0.1 min division and ±0.2 accuracy, essential for protein quantification in molecular diagnostics and biochemistry research.
• Refractive Index Range: 1.3330–1.3900 nD with a resolution of ±0.0001 nD and ±0.0003 nD accuracy, supporting applications in biomedical engineering and synthetic biology where precise optical measurements are required.

The device supports essential workflows in biotechnology, including bioprocessing and biomolecular analysis, and is widely adopted in clinical laboratories focusing on molecular diagnostic testing and biopharmaceutical quality control. Rechargeable batteries are not included, ensuring customization for laboratory power requirements. Its compact design makes it suitable for live-cell imaging facilities and fluorescence analysis labs needing accurate refractive index data.

This refractometer provides reliable, repeatable measurements to support research in cell imaging, neuroscience, and biomanufacturing pipelines.
