Limitations of use / Operating limits

Chlorinated and fluorinated hydrocarbons or chemical combinations which form deposits may make the piston difficult to move or may cause jamming.

Compatibility of the instrument for a special application (e.g., trace material analysis) must be checked by the user. For additional information, please contact the manufacturer.

The instrument is not autoclavable!

This instrument is designed for titrating liquids, observing the following physical limits:

  • +15 °C to +40 °C of instrument and reagent
  • Vapor pressure up to 500 mbar
  • Viscosity up to 500 mm²/s
  • Altitude: maximum 3000 m above sea level
  • Relative humidity: 20% to 90%.
