Combination Calorimeter LECC-6765

  • Combination Calorimeter LECC-6765 for laboratories that want to perform both Solution and Semimicro Oxygen Bomb calorimetry tests. This includes the 6772 Calorimetric Thermometer module plus a calorimeter module and conversion parts for both the 6755 Solution Calorimeter and the 6725 Semimicro Calorimeter. This option has been popular with teaching laboratories that wish to include both types of experiments in their laboratory sessions.

    Conversion Sets

    The 6729 and 6759 Conversion Sets are also available for users who have one of the principle calorimeters and wish to add the second capability to their installation.
