Sper Scientific 300005 Clinical Refractometer - Urine Specific Gravity & Refractive Index - Portable & Water-Resistant with Calibration Tools & Protective Case - 2 pc

Sper Scientific portable refractometers work in ambient light with no battery or other power source necessary. A refractometer measures the extent to which light is bent (refracted) through a liquid sample. They are commonly used to help identify or confirm the identity of a sample, assess the purity of a sample, or determine the concentration of a solute in a solution. They can be used in labs, on production lines, in the field or anywhere. Simply place a drop or two of a sample on the prism and read the results immediately. With reasonable care, their reliability, precision, and optical performance will last forever.

• ACCURATE URINE SPECIFIC GRAVITY MEASUREMENT: Measures urine specific gravity (1.000 to 1.050) and refractive index (1.3330 to 1.3600) with high precision for clinical and laboratory use.
• PORTABLE & BATTERY-FREE OPERATION: Works in ambient light, eliminating the need for batteries or power, making it ideal for labs, medical settings, or field use.
• COMPLETE ACCESSORIES INCLUDED: Comes with a hard carrying case, calibration tools, transfer pipettes, protective case, and detailed instructions for immediate and accurate setup.
