Quick screening calorimeterIt is a professional testing instrument used to evaluate the thermal stability, reaction heat effect, and potential hazards of substances, widely used in the fields of chemical engineering, medicine, materials science, and scientific research. Its core function is to quickly assess the thermal hazard of a substance by monitoring the temperature and pressure changes of the sample in real-time under heating or constant temperature conditions, analyzing heat release and pressure generation data.
This instrument adopts advanced thermocouple sensors and high-precision pressure measurement devices, supporting multiple temperature scanning modes (such as isothermal, scanning, and step modes). The temperature control range is usually from room temperature to 400 ℃, and the temperature resolution can reach 0.001 ℃ to 0.01 ℃. The pressure range covers 0 to 20MPa, which can meet different experimental needs. Its dual channel design can simultaneously test multiple samples (including reference samples), significantly improving testing efficiency and accuracy. The single experiment time can be shortened to 30 minutes to 2 hours, far superior to traditional adiabatic calorimetry.
Quick screening calorimeterThe main characteristics include the following aspects:
1. Efficiency: It can achieve parallel testing of multiple samples, significantly shorten experimental time, improve screening efficiency, and is suitable for quickly screening substances with specific thermal effects in a large number of samples.
2. Accuracy: Advanced heat flow technology and high-sensitivity heat detection system are used to accurately measure the heat released or absorbed by the sample during physical or chemical changes, and detect extremely weak thermal changes. Some instruments also have functions such as automatic recognition of oxygen bombs and automatic calibration of heat capacity, reducing human errors and ensuring the accuracy of measurement results.
3. High degree of automation: Usually equipped with automated sample loading systems and computer control software, users only need to set the test parameters to achieve one click operation. The instrument will automatically record data and generate reports, greatly improving the convenience and repeatability of experiments.
4. Functional diversity: Supports multiple testing modes, such as constant temperature mode, scanning mode, dual gradient scanning mode, etc., to meet different types of samples and experimental needs. It can also provide data on changes in heat release and pressure over time, as well as key thermal behavior parameters such as reaction initiation temperature, heat release temperature rise, specific heat release, and gas production, providing comprehensive information for studying the thermal properties and reaction processes of substances.
5. Widely applicable: Suitable for chemical, pharmaceutical, scientific research and other fields, it can be used to evaluate the thermal stability of chemicals, chemical process safety, material compatibility, as well as to conduct thermal stability and compatibility testing of drug candidates, screening of chemical synthesis reaction conditions, optimization of material processing, etc.
6. High safety: equipped with experimental status indication and overpressure/overtemperature alarm functions, the furnace cover is automatically locked, and can only be opened when the pressure and temperature inside the furnace reach the safe range. At the same time, inert gas can be connected to quickly cool down the furnace body after the experiment, ensuring the safety of experimental personnel and equipment.
