Automatic Pressure Tracking Adiabatic Calorimeter Accelerating Rate Calorimetry
The instrument can function as:
The precision and accuracy of APTAC® 264 test results help companies in scaling up process designs to production scale by:
APTAC® 264 can be used for the thermal analysis of solid or liquid chemicals or for gas/liquid, liquid/liquid, gas/solid, and liquid/solid mixtures. It can also be used for process simulation of batch and semi-batch reactions, fire exposures, emergency relief venting, and physical properties measurement.
