Laboratory Refractometer

Sper Scientific - Model 300006,11 - Salt Refractometer

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. Certificate of calibration is available for these refractometers.

Sper Scientific - Model 300033 - Laboratory Digital Refractometer

These high-precision Digital Lab Refractometers measure concentrations in brix, salinity, refractive index and clinical parameters with full scale accuracy of 0.1% using CCD scanner (= linear scanned array imaging) technology. These refractometers are simple to use,calibrates to distilled waterand requires a sample of only 0.4 ml. They instantly display temperature in addition to multiple scales with the unit of measure indicated on the large LCD. The sophisticated microprocessor provides automatic calibration, automatic temperature compensation (ATC), automatic shutoff (after 3 minutes), and visual min/max alarms.

Model 300001,02,03,10 - Sugar Refractometer 3 Ranges 0 to 80%

Salinity - Model 300035 - Laboratory Digital Refractometer

Measure concentrations in brix, salinity, refractive index and clinical parameters with full scale accuracy of 0.1% using CCD scanner (= linear scanned array imaging) technology . Simple to use. All models calibrate to distilled water and require a sample of only 0.4 ml. Instantly displays temperature in addition to multiple scales with the unit of measure indicated on the large LCD. The sophisticated microprocessor provides automatic calibration, automatic temperature compensation, automatic shutoff (after 3 minutes), and visual min/max alarms. Low power consumption enables 5000 readings, before the LCD indicates that the battery should be replaced. The water resistant design protects the electronics from wet environments and makes for easy clean ups. Comes ready to use with a 9V battery, distilled water, a transfer-pipet, instructions and a protective case.
