Precision Systems Osmette™ A Osmometer

Catalog No. 128275
Click to view available options
Display Type:
Digital

Automatic digital osmometers measure osmolality in mOsm/kg H2O. Osmette A Osmometer uses the freezing point depression method to provide a quick, accurate indication of total concentration. Instruments measure freezing points of solutions to 0.001°C, then directly translate them to measure of concentration.

Easy to Use

  • Add sample tube to well, lower operating head to insert wire and thermistor temperature probe into the sample
  • Freezing point is detected by the probe, with accuracy of ±0.001°C
  • Digital display shows results directly in mOsm/kg H2O
  • Entire cycle takes between one-half and one minute per sample
Speedy and convenient
  • Fast cooldown, completely zero-stable meter
  • Reach operating temperature in <15 min. vs. 40 to 60 min. for other cryoscopic devices
  • Eliminate Dewar flasks, ice baths, calculations
  • Generate precise results in just 50 to 70 sec.; process 40 to 60 samples per hour
  • Minimal training; simple two-step calibration takes less than five minutes
  • All models hold calibration, eliminating daily calibration

Osmette A, Model 5002
