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. Therefore, the YRT-3 melting point meter is equipped with a temperature preset function, which can control the temperature at the preset temperature
Product Details
Performance characteristics: Yrt- 3The melting point meter has real-time temperature display function and recording keys for initial and final melting points, which can record the melting point values in the initial and final melting states. According to the pharmacopoeia's regulations on melting point determination, the sample should be tested at a liquid temperature below its melting point value by approximately10℃Add a temperature transfer solution and then raise the temperature at a constant rate as required by the pharmacopoeia until the sample melts. for thisYrt- 3The melting point meter is equipped with a temperature preset function, which can control the temperature at the preset temperature. The preset value that has been recorded for this shutdown is saved, and the preset temperature for the next startup will be the preset value for this shutdown. After reaching the preset temperature, the delay is about1Minute, keep the liquid in a stable temperature state, and the buzzer will prompt. When the sample melts, the initial melting point and final melting point values can be recorded using the initial melting and final melting keys Yrt- 3The melting point meter has three working states: reset state, temperature control state, and startup test state The initial melting point bond and final melting point bond 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 is recorded Record the melting point value of another sample.
