An Introduction to the THT ES-ARC for process safety in the chemical industry. This video gives a brief overview of the instrument and how it works.

The Micro Reaction Calorimeter is an isothermal calorimeter for testing small volume chemical samples (up to 1.5ml). It comes with a broad range of functionality, including temperature scanning, step-isothermal, heat capacity measurement and titration.

The Rapid Screen Device is a safety calorimeter designed for quick yet accurate safety evaluation of multiple chemical samples in a single test. This video provides a brief overview of the instrument and its functions.

A step-by-step video showing the process of analyzing data from the Rapid Screening Device using the RSD-RAP analysis package.

The test examined in this video used three samples of di-tertiary butyl peroxide (DTBP) of varying concentration in toluene.

The video shows evaluation procedures to obtain thermodynamic and thermokinetic information from the three samples. The RSD can run up to 5 samples and a reference (6 total samples) and can operate in ramp heating mode, as is the case here, or isothermal mode.

A longer video showing the test procedure for a ARC heat-wait-seek on a peroxide sample.

The video shows the test setup in software, as well the software running and collecting data at various stage during and after the test.

This short video is a step-by-step guide to the process of setting up a heat-wait-seek test on a sample with unknown properties.

The test settings used here run the ARC in small temperature steps over a large temperature range (50-400 degrees) in order to find any exothermic response that might occur in the sample. Once this initial test is carried out, the test may be repeated, with the test starting closer to the real onset temperature.

This short video is a step-by-step guide to the process of setting up a drift test in the ES-ARC software.

The purpose of a drift test is to check the thermal stability of the instrument at various temperatures using an empty bomb. If the drift test indicates excessive drift in temperature using an empty bomb, then recalibration of the instrument may be required.

This short video is a step-by-step guide to the process of setting up a calibration test in the ES-ARC software.

This calibration is applicable to a standard chemical sample test using an 8ml ARC bomb. Different types of tests may require more specialized calibration procedures, and the versatility of the software allows for this.

This video is a practical demonstration of how to place a standard calorimeter inside the ES-ARC blast box and make all the connections to the calorimeter.

This video demonstrates:
- Positioning the calorimeter in the blast box
- Connecting the cables to the calorimeter thermocouple sockets
- Connecting the power leads to the calorimeter power sockets
- Connecting an ARC bomb to the top of the calorimeter
- Connecting the pressure line to the top of the calorimeter through-tube
- Closing and securing the blast box doors

A comparitive video of two overcharge tests carried out on two different rechargeable lithium-based cells.

The batteries examined here have similar charge capacity, but behave very differently when overcharged.

The calorimeter provides a strong enclosed chamber for dangerous tests such as these as well as an adiabatic environment to quantify heat production.

The new EV+ calorimeter has a built in video-facility as well as many other battery performance and safety testing facilities.
