5008 CRYETTE A Automatic High Sensitivity Dual Range Petroleum Cryoscope

Petroleum Cryoscopes are used globally at well sites and central labs to determine the molecular weight of petroleum products. From characterization of cracking fractions to salinity testing.

Laboratory Model Automatic Cryoscope for molecular weight, solution concentration, and freezing point depression determinations for aqueous and benzene solutions for 2.0 mL samples, featuring:

  • Two selectable ranges: -2.0 to 0°C and +2.5 to +5.5° C
  • Results displayed in o C of Freezing point
  • Adjustable bath temperature allowing optimum temperature settings for particular solvents
  • 2-step calibration with non-interacting calibration controls
  • Cool down in < 15 minutes – Precise air temperature environment during sample isolation


These instruments are used by major oil companies to identify and QC their products.
