Product Description

Drd-3 Melting Point Tester Reagents Fragrances Dyes
Applications: For testing the melting points of drugs, reagents, fragrances, dyes, and other organic crystalline materials

Performance:
  1. DRD-3 drug melting point instrument adopts the capillaries prescribed by the Pharmacopoeia as the sample tube and the liquid temperature transfer mode, and adopts the microcomputer control program to heat up, work reliably, high temperature control precision, accurate measurement, good reproducibility and easy operation. The design fully complies with the regulations and requirements of the instrument and measuring method in the melting point determination method in the Pharmacopoeia of the People's Republic of China. It also meets the requirements for melting point determination in the Pharmacopoeia of the United States, Britain and Japan. It can be widely used in medicine and chemical reagents. In the production and testing of industries such as perfumes and dyes, the melting point of organic crystalline materials is measured.
  2. Melting point tester applicable standard: "People's Republic of China Pharmacopoeia" 2015 edition
  3. The melting point tester strictly carries out the verification test specified in the "Capillary Melting Point Tester" approved by the State Bureau of Technical Supervision before leaving the factory to comprehensively verify the instrument.

Melting point measuring instrument structure and characteristics:
DRD-3 adopts advanced microprocessor control technology and advanced hardware design to ensure long-term stable and reliable instrument.
The temperature measurement adopts Japanese original film A-grade platinum resistance component sensor, which has high temperature measurement accuracy, good linearity, high reliability and long service life.
The automatic magnetic stirring system controls the high speed rotation of the stirring rod to ensure the temperature of each point of the temperature transfer liquid is uniform. (The maximum use temperature of the stirrer is 350oC)
The temperature heating is monitored by the microcomputer in the instrument in real time. The temperature can be quickly raised to the preset value according to the requirements, and then the melting point is measured according to the required constant temperature. When the sample is melted, the initial melting and final melting bonds can be utilized to record two melting point values. The entire system achieves full-closed automatic control.
Using large-screen high-definition LCD screen, users can enjoy intelligent operation according to the screen prompts. Each operation process gives Chinese character prompts and quantitative indicators.

Main technical indicators of melting point tester:
  • Melting point test range: room temperature to 280oC
  • Heating rate: 0.5oC/min 1oC/min 1.5oC/min 3.0oC/min fourth gear
  • Linear heating rate deviation: < 10%
  • Temperature rapid preset range: Any preset within the range of room temperature to 270oC
  • Transmission medium: methyl silicone oil
  • Transfer temperature cup: 250ml high beaker
  •  Melting point test accuracy: tolerance less than 200oC ± 0.5oC
±100oC tolerance when greater than 200oC
  • Indicative resolution: 0.1 oC
  • Using ambient temperature: 15oC-30oC
  • Power supply: AC220V±10% Frequency 50Hz Power 200W

The instrument is divided into three working states:
  • Standby state---preset temperature, select heating rate, observe the number of measurements of similar samples after starting up, and the maximum, minimum and average values of initial melting after data processing in the instrument, final melting maximum and minimum And average.
  • Preparation state---Start the stirring and heating system to quickly raise the temperature of the temperature transfer liquid to the preset value. (The display dynamically shows the entire temperature change process in real time) After the preset temperature is reached and constant, the buzzer sounds prompt.
  • Test status---Into the sample start test, the system will increase the temperature according to the preset heating rate. When the sample is melted, the initial melting point and the final melting point can be used to record the initial melting point and the final melting point respectively. The initial melting and final melting keys have the functions of repeating recording and covering the previous operation, which is convenient for the user.
  • powerful data processing capability, can automatically record and display the number of tests, initial melting maximum and average values, final melting maximum and average values
