Ultra Stable Isothermal Calorimeter

Monitor decomposition of energetic materials

  • Detect heat generation in µW range
  • Low volume (4ml) disposable glass cells for solids, liquids and mixtures
  • Automatic cell switching: provides excellent baseline stability over extended time period.
Ultra Stable Isothermal Calorimeter

Cell Switching Technique Explained
Cell switching simply means – swapping the sample for the reference position within the calorimeter. The heat release from the sample recorded as a positive heat release when the sample vial is in the sample position; when the sample vial is in the reference position the heat is negative. Therefore the difference between the heats divided by two is the heat release from the sample. This method is useful as here lengthy calibration and thermal equilibration is not needed and any error due to baseline uncertainty or baseline drift over time is removed.
