Thermal temperature intelligent control, with rushing warm small, fast heating, temperature characteristics. Hot 220V/300W Nickel-chromium wire, long service life and easy replacement.

Equipment Description:

Material's melting point is the temperature at which a substance from solid to liquid. In the field of organic chemistry, melting is the primary means to identify the nature of the substance, is one of the important method for determination of purity. Visual micro-fusion point determination meter is the study and observation of deformation of material in heating condition, color and material physical processes such as Tri-State into a powerful means of detection.

Slides of this instrument method to determine the melting point of the substance, deformation, discoloration, etc; Capillary method measure the melting point of the pharmacopoeia can also be used, especially for dark-colored samples, such as pharmaceutical intermediates, pigment, accelerator, such as melting point and melt it observed from beginning to end the whole process.

Structure principle:

The instruments and microscopes and heating for separate structure, connected by simply inserting special heat sensors, Assembly of simple, easy to use microscopes to observe samples reflect changes of heating and melting of the entire process. Heating with electric heating, with a dedicated radiator for fast cooling. Can be used in carrier-method for measuring, you can also use measurement melting point capillary.

Operation method:

1. New instruments, the power is switched on, switch to the heating position, viewed from the microscope stage center hole is in the field of view, left side, can be resolved around a microscope. Before and after the Center, you can loose heat on both sides of the two screws, be careful not to, can be simply loose, then push before and after the thermal Center, tighten two screws. When you do promote hot, in order to prevent heat burns your fingers, pull the lowest numbered position band switches and potentiometers, counter-clockwise rotation.
2. Heating rate adjustment, this stopwatch watches available to adjust. Stopwatch when a certain value, record the temperature value, then stopwatch to a circle (one minute) in the recorded temperature value. Continuous recording until you've requested measurement of melting point value, the heating rate: 1 ° c/min. too fast or too slow by rough harmonic tuning knob to adjust. Note that even if crude harmonic tuning knobs fixed, but with the increase of the temperature, the heating rate will be slower.
3. On the sensor of the thermometer, insert it into the hot hole, if it is misplaced, it will affect the accuracy of measurement.
4. To be precise the melting point, melting point measuring standards calibration. Calculate correction. (Melting point measured-value value = standard values), as a basis for measuring the correct. Note: directives for the value you have to measure the melting point melting point sample value, the closer the better. At this time, (the melting point of the sample the sample value = measured value + correction).
5. Measure the sample to be dried, or in a dry tank to dry, powdered fine should be held.
6. When using load-the glass measure, recommended that the cover glass (thin) on a hot pad, put on powder, and then uploaded on measurement of wave plate.
7. Minimum one digital temperature display (such as 8 or 7 beats) should be read as 8.5 degrees centigrade.
8. Repeated measurements, switch is in the off State, then heat stops. When cooled to below 10, into the sample, switch to heating, you can conduct repeated measurements.
9. Testing is completed, cut off power supply, when the heat cools to room temperature, instruments can be put inside a box.
10. Recommends you use 1 c/min heating rates measure the melting point temperature values recorded on first use 1 c/min heating rates when the band switches and potentiometer the number later used this location to get your required heating rate. And please note that (1) effects of temperature; Under the number of the same band switches and potentiometers, lower the room temperature, heating rate and slower. (2) electronic components: the aging of the electronic components, heating rate is constant, the potentiometer the number varies, as long as the fine-tuning. Number larger, faster heating rate.

Main features:

1. The measuring instrument using capillary.
2. According to the special requirements of the instrument carrier--carrier measuring method can also be used.
3. This instrument adopts LED digital melting point temperature values are displayed.
4. This structure is simple, reliable and easy to use.
5. Heating rate can be adjusted continuously.
