Osmomat 3000 Freezing point osmometer

The Gonotec® Single-Sample Freezing Point Osmometer is especially designed for routine measurements in the medical field and is also very suitable for measurements in research and industry.

The Osmomat 3000 determines the total osmolality of aqueous solutions. The instrument requires very small sample volumes and can thus be applied for extreme measuring tasks. Its rapidity allows serial measurements in a very short time.

Advantages

  • The Osmomat 3000 can be controlled easily and comfortably via a touch screen display.
  • Step by step user guidance through all measurement functions.
  • QM assistance for the laboratory supervisor.
  • 2 or 3 point calibration.
  • The results are sent to the optional built-in printer in document-ready format.
  • For data transfer to a PC it can be connected via USB or RS232.
  • The last result remains available for reading even after automatic switching to stand-by mode.
  • The robust design of the measurement equipment makes the Osmomat 3000 easy to handle and maintain.
  • Choice of language.
  • Automatic calibration by using Gonotec calibration standards.

Measurement: Freezing point osmometer

Freezing point osmometer

The total osmolality of aqueous solutions is determined by comparative measurements of the freezing points of pure water and of solutions. Whereas water has a freezing point of 0 °C, a solution with saline concentration of 1 Osmol/kg has a freezing point of -1.858 °C.
