MMC 274 Nexus®

Multiple Module Calorimeter

Various Modules in One Calorimeter

The MMC 274 Nexus® consists of two parts: the base unit with electronics and the exchangeable calorimeter module. This guarantees maximum flexibility.

Exchangeable calorimeter modules are available for different applications. The Accelerating Rate Calorimeter (ARC®) module can be used for standard process safety work. The External heater module can be employed for more sophisticated measurements.

Process Safety: The ARC Module

Heat-Wait-Search and Pressure Tests
A defined volume of a sample (ml scale) is placed in a tube-shaped container. The container is surrounded by a sophisticated heating system. Depending on the operating mode, the surroundings of the tube vessel are controlled to the same temperature as the sample. If there is no temperature difference between the surrounding heaters and the sample, then all the heat generated by the sample stays inside the sample.

Key Features of the ARC Module

  • Heat-Wait-Search tests for thermal runaway reactions
  • Ramp mode for fast screening of unknown samples
  • Pressure measurement

The Scanning Module

Isothermal and Scanning Tests

Here, an additional heater is placed on the outside of the sample container. This allows for a defined power input and more accurate temperature control of the sample. The external heater is useful for running isothermal and constant temperature ramp tests, especially in those experiments where reaction energies are higher.

Key Features of the Calorimeter with the Scanning Module

  • Scanning mode as with DSC via constant heating rate or constant power
  • Isothermal mode as with DSC
  • Pressure measurement
  • Injection of liquid samples during the measurement
