Overview
The SUOGUANG WRX-5A microscopic melting point tester is a new type of melting point tester designed with micro-control technology. It is used for microscope research, determination of the characteristics of the tested substances, and TOA analysis. It can be used not only for melting point determination of trace samples, melting point determination of slice samples, but also for bioengineering thermodynamic research. The instrument has stable and reliable performance, simple and convenient operation, and is a required instrument for melting point analysis of laboratory substances in the chemical industry and research.
Features
1. Multifunctional dual-use design, capillary method or coverslip method can be used to measure the melting point of substances, and the edge guide groove design of the hot table is convenient for slide loading and preventing slippage;
2. High magnifying glass to clearly observe the melting details of the sample, suitable for conventional transparent crystals, deep Color samples, low purity samples, amorphous samples, thermal analysis or carbonization samples, slice samples, filamentous samples and trace samples;
3. It has the functions of starting temperature setting, eight-speed linear heating rate setting, current furnace temperature display, instrument status display, and automatic recording and display of initial and final melting temperature.
4. Precise control of heating rate, not affected by the initial temperature, improve measurement Repeatability and accuracy;
5. Adopting the principle of microcomputer control, equipped with membrane buttons and liquid crystal display, the operation is comfortable and simple, and the results are intuitive.
6. Collaborative design of software and hardware realizes precise control of furnace temperature, Measurement accuracy, Repeatability and Reliability are high, and the performance is comparable to that of automatic microcomputer Melting point meter.
Principle
The instrument is based on micro-control technology, by setting the initial temperature and linear heating rate, the temperature rise of the hot table is precisely controlled, the melting process of the sample is observed under the Microscope, and the initial and final melting temperatures are automatically recorded to realize the determination of the melting point of the substance and the thermodynamic analysis.
Applications
Chemical industry, synthetic fiber, biology, mineralogy, criminology, polymer determination, unit component phase change determination, multi-component phase change determination, isothermal part test, seed crystallization process, wood pyrolysis, bioengineering thermodynamics, temperature-related biological specimen research
Steps
1. Set the starting temperature.
2. Select one of the eight linear heating rates;
3. Use the capillary method or coverslip method to load the sample.
4. Microscope observation of sample melting process;
5. The instrument automatically records and displays the initial and final melting temperatures.
Notice
• Power supply voltage of 220 +/- 10% V;
The thickness of the slide should be within the range of 0.8 to 1.2 mm.
The thickness of the coverslip should be 0.17mm.
• Check whether the instrument status display is normal before use;
• Avoid sample heat analysis or carbonization affecting Measurement accuracy;
• Pay attention to the temperature of the heating table during operation to prevent burns.
