Overview
The YRT-3 drug melting point meter adopts a capillary tube as the sample tube and liquid temperature transfer method specified in the pharmacopoeia. It uses a microcomputer controlled program for temperature rise, reliable operation, high temperature control accuracy, accurate measurement, good reproducibility, and easy operation. The design of this instrument complies with the provisions and requirements of the Chinese Pharmacopoeia on instrument tools and measurement methods for melting point determination, as well as the requirements of the pharmacopoeia of the United States, Britain, Japan and other countries for melting point determination. It can be widely used in the production and scientific research of industries such as medicine, chemical reagents, spices, dyes, etc., to measure the melting point of organic crystalline substances.
Product Details
Performance Characteristics:
1. The YRT-3 melting point meter has undergone significant improvements based on the YRT-2 melting point meter, adding real-time temperature display and recording keys for initial and final melting points, which can record two melting point values.
2. According to the pharmacopoeia's regulations on melting point determination, the sample should be placed in a transfer solution when the liquid temperature is about 10 ℃ lower than its melting point value, and then heated at a constant rate as required by the pharmacopoeia until the sample melts. For this purpose, the YRT-3 melting point meter is equipped with
Temperature preset function.
3. The preset value has been recorded for this time, and the preset temperature for the next startup will be the preset value for this time.
4. After reaching the preset temperature, delay for about 1 minute to keep the liquid in a stable temperature state, and the buzzer will sound
5. When the sample melts, the initial melting point and final melting point values can be recorded using the initial melting and final melting keys
6. The YRT-3 melting point meter has three working states: reset state, preparation state, and test state
7. The initial melting point key and final melting point key can also be used to measure the melting points of two samples. The initial melting point records the melting point value of one sample, and the final melting point records the melting point value of the other sample.
