Osmotic Pressure

The OM-6060 measures the osmotic pressure of body fluids such as blood serum, plasma and urine.

Noise-free and accurate measurement using Freezing-point depression

Micro sample volume

  • Required sample volume: only 200 μL

Free calibration

  • 3-point calibration
  • 2-point calibration
  • Calibration data is memorized unless the power is turned off

Various measurement modes

  • Osmotic pressure ratio measurement
  • Control measurement
