Overview
The SGW X-4 Melting point meter is a professional instrument of the INESA brand for the determination of the melting point of substances, especially for the analysis of crystalline organic compounds. The instrument uses the microscope observation method, supports both capillary method and slide-coverslip method (hot table method) measurement methods, and has a temperature range from above room temperature to 320 ° C. High Accuracy and ease of operation.
Features
1. Support capillary method and hot table method two measurement methods, flexible to adapt to different sample needs.
2. Microscope observation, magnification of 40X, easy to clearly observe the sample melting process.
3. Wide temperature range, from RT + to 320 ° C, covering the melting point of common organic compounds.
4. Temperature resolution is 1 ° C, high repeability, +/- 1 ° C at ≤ 200 ° C, +/- 2 ° C at > 200 ° C.
The instrument is compact, with dimensions of 215 × 140 × 395mm and a net weight of 3.5kg, making it easy to move and operate.
6. The power requirements are 220V +/- 22V 50Hz +/- 1Hz, which is suitable for standard laboratory environment.
Principle
The SGW X-4 microscope Melting point meter is based on the microscope observation method, which determines the melting point by heating the sample and monitoring the temperature change in real time. In the capillary method, the sample is loaded into the capillary tubing and placed on a heating table; in the hot table method, the sample is placed between the slide and the coverslip. The instrument heats the sample to the melting point, and the user visually observes the change of the sample state through the Microscope, and records the melting point value in combination with the temperature display.
Applications
Determination of Crystal Organic Compounds in Chemicals, Spinning & Weaving, Fuels and Fragrances
Steps
1. Prepare the sample: Select capillary tubing or slide-coverslip according to the measurement method.
2. Place the sample: Place the sample on a heating table.
3. Set parameters: Turn on the power and adjust the Microscope for clear observation.
4. Heat the sample: Start the heating program and slowly heat up.
5. Observation record: Visually observe the sample melting process through a Microscope and record the melting point temperature.
6. End the measurement: turn off the power and clean the sample and instrument.
Notice
• Power frequency 220V +/- 22V 50Hz +/- 1Hz before use to avoid voltage instability affecting accuracy.
• Pay attention to slow heating during operation to prevent excessive temperature from damaging the sample or instrument.
• Keep the Microscope clean to ensure clear observation.
• Clean up the heating table and sample residue in time after measurement to avoid contamination.
• The net weight of the instrument is 3.5kg, handle it with care to prevent collision.
• Only for the determination of crystalline organic compounds, not for Miscellaneous type samples.
