CTAP-500A is a low thermal inert high-end adiabatic acceleration calorimeter developed based on the principle of real-time compensation of sample heat loss power.
Product introduction
CTAP-500A low thermal inert adiabatic acceleration calorimeter breaks through the bottleneck of the existing adiabatic acceleration calorimeter that “the temperature rise energy of the sample pool comes from the reaction heat release of the sample being measured”, and realizes the separation of the thermal inertia factor and the heat capacity of the sample pool, without the need for thermal inertia factor Calibration can obtain accurate thermodynamic and kinetic parameters. The instrument is compatible with the heating-waiting-searching mode and can seamlessly replace the classic adiabatic acceleration calorimeter in chemical process development, optimization and amplification and chemical thermal risk assessment in the fields of organic chemistry, pharmaceuticals, agricultural fertilizers, fine chemicals, etc. , and because its measurement data accuracy is significantly improved compared to the classic adiabatic acceleration calorimeter , it can effectively promote the scientific research of chemical reaction kinetics.
Features
1) Simulating an ideal adiabatic environment, the more accurate thermal behavior parameters such as reaction starting temperature, maximum reaction rate, and adiabatic temperature rise can be directly measured
2) No need for thermal inertia factor correction, thermodynamic and kinetic parameters that are independent of the heat capacity of the sample container can be calculated, achieving accurate evaluation of key indicators characterizing the thermal hazards of chemical reactions/chemicals
3) Compatible with classic heating-waiting-searching (HWS) mode, isothermal mode, and scanning mode, which can realize seamless replacement of classic adiabatic accelerating calorimeter
4) Equipped with adiabatic scanning mode, it can realize rapid and accurate screening of thermal hazards of chemicals/chemical reactions
5) Equipped with professional data analysis software, it can realize the automatic calculation of exothermic starting temperature, adiabatic temperature rise, activation energy, pre-exponential factor and other parameters
6) The software integrates the reaction safety risk assessment methods and standards of the State Administration of Work Safety’s “Guidelines for Safety Risk Assessment of Fine Chemical Reactions” to achieve a one-stop assessment of the hazard level of the reaction process
7) With experimental status indication and overpressure and overtemperature alarm functions
8) The furnace cover has automatic lifting function to ensure safety and convenient operation
