  • Bath with Peltier cells controlled by software, with no cooling liquid
  • Induced ventilation
  • Operating ambient temperature: +5°C to 36°C
  • Automatic calibration
  • Lash and agitation width adjustment controlled by software
  • Results in mOsm/Kg units and °C
  • Sample volume: from 50 to 200 µl (with disposable plastic tubes)
  • Analysis duration: about 3 minutes/test
  • Warm up time: about 5 minutes
  • Measurement range: from 0 to 1500 mOsm
  • Resolution: 1 mOsm/Kg
  • Repeatability and reproducibility: ±2 mOsm (from 0 to 600 mOsm) or ±0,5% (from 600 to 1500 mOsm)
  • Power supply: 110/220 V, 50/60 Hz, 100 W
  • Dimensions: 285x380x450 mm (wxdxh – with head up)
  • Net weight: about 10 Kg.
