Features
1. Using photoelectric automatic detection technology to automatically display the initial and final melting points
2. Color LCD screen display, numeric keypad input easy to operate
3. Linear dispersion can be automatically recorded and the average melting point can be calculated
4. High Linearity platinum resistance and PID adjustment technology to ensure measurement accuracy
5. Support RS232/USB communication interface, can print or save working parameters
6. Comply with the capillary tubing sample tube standard stipulated in the Pharmacopoeia
7. Provide eight adjustable heating rate (0.2-5 ℃/min)
8. Temperature resolution up to 0.1 ℃, good measurement repeability
Principle
The instrument monitors the temperature change of the sample in real time through the high Linearity platinum resistance detection element, and uses PID adjustment technology to precisely control the heating process. When the sample reaches the melting point, the photoelectric system automatically detects its state change, calculates and displays the initial and final melting points through the built-in algorithm, and records the complete melting Linear dispersion.
Applications
Pharmaceutical, chemical, materials science, quality control, laboratory research
Steps
1. Prepare capillary tubing sample tubes that meet specifications (outer diameter φ 1.4mm, inner diameter φ 1.0mm, length 90mm)
2. Load the sample into capillary tubing, the sample height is about 3mm
3. Set the desired heating rate through the numeric keypad
4. Start the measurement program, the instrument automatically detects and displays melting point data
5. The measurement results can be saved or printed through the communication interface
Notice
• Power frequency within 220V +/- 22V range before use
The height of the sample should be strictly controlled to 3mm.
• Select the appropriate heating rate to ensure measurement accuracy
• Regularly calibrate the instrument
• The size of the capillary tubing must meet the specifications
• Avoid use outside the temperature range (RT +~ 320 ℃)
• The instrument should be placed on a stable and flat workbench
