Refractometers have been used for measuring the concentration of solutions for more than a century. Their primary purpose is to measure the degree at which light bends as it passes through a medium, and is used in a wide range of applications and industries as a quality control and diagnostic tool.

Laxco Analog Lighted Refractometers are designed by US engineers and include many features packed into a handheld device.

Each unit is inspected in the United States by a factory qualified technician under a ridged quality control process to ensure accuracy and performance.

Key Features:

  • Sealed calibration screw is locked on the bottom of the unit to prevent water from entering into the system
  • Quickly calibrate the instrument with a turn of a screw, and distilled water
  • Comfortable rubber eyecup blocks out ambient light, and allows for crystal clear viewing of readings
  • Automatic temperature compensation prevents the need for constant re-calibration of the instrument. As the ambient temperature changes, the scale will automatically compensate for the difference in the degree of refraction. This ensures an accurate reading every time
  • All metal construction and water resistant seal between prism and main body protects and prevents damage to internal objective lens
  • Flat bottom allows the instrument to be set on a flat surface without the worry of it rolling
  • Rubber hand grip is comfortable, easy to grasp. Its non-slip pattern grip reduces that chance of accidentally dropping the instrument
  • One-piece U-shaped metal hinged daylight plate provides durability of frequent opening and closing. Two screws allow the daylight plate to be easily replacement in case of accidental damage
  • Machined hole for hanging the refractometer in a convenient location
  • Ball bearing hinged daylight secures the daylight plate in the up and down position
  • Magnified scale and all glass optics creates the sharpest readings on the market
  • Push bottom monetary switch allows for easy operation of the LED illumination
  • Focusable eyepiece allows for crisp focus of reading line
  • Carrying lanyard
  • Two sample applicators are mounted to the bottom side of the refractometer, for convenience
  • LED illuminates the scale without the need for ambient light
  • Operates both with ambient light and LED
  • Portable, easy to use design

Clinical Models:

Quickly and accurately get an indication of basic health parameters such as dehydration and blood plasma protein levels. Laxco Lighted Analog Clinical Refractometers uses three-scales to measure Total Serum Protein, Urine Specific Gravity, and Refractive Index, and ideal for use in quality control, research, and clinical laboratories.

  • Urine Specific Gravity: 1.000ppt to 1.050ppt with granularity to measure down to 0.2ppt at a 0.2ppt degree of accuracy
  • Serum Protein: 0g to 12g/100mL with granularity to measure down to 0.2g/100mL at a 0.2g/100mL degree of accuracy
  • Refractive Index: 1.334nD to 1.360nD with granularity to measure down to .0005nD at a 0.0005nD degree of accuracy
