laboratory electric heating mantle price
The electric heating mantle is a kind of general heating instrument in the laboratory. It consists of a hemispherical heating inner sleeve and control circuit composed of alkali-free glass fiber and metal heating wire. It has the characteristics of fast heating, high temperature, easy operation, and durability. It is the most ideal instrument for accurate temperature control heating test.
The laboratory electric heating mantle is indispensable equipment in the short-path distillation system, which provides a heat source for the entire short-path distillation equipment.
Function classification:
1. Electronic thermostat electric heating jacket: voltmeter to regulate temperature
2. Constant temperature digital display electric heating jacket: digital display meter adjustment and display temperature
3. Digital display stirring electric heating jacket: Digital display meter adjusts and displays temperature, with stirring function
4.Temperature-stirring electric heating jacket: voltmeter adjusts temperature and has the stirring function
5. Microcomputer electric heating jacket: The control circuit is controlled by a microcomputer, and the temperature control is more accurate.
Temperature control range:
1 Ordinary electric heating jacket: up to 400 degrees
2 High-temperature electric heating jacket: Due to the use of a more high-temperature-resistant inner sleeve woven material. The highest heating temperature of the high-temperature electric heating jacket can reach 800-1000 degrees
Precautions:
1. The instrument should be well-grounded.
2. When it is used for the first time, there is white smoke and odor coming out from the sleeve. The color changes from white to brown and then to white, which is normal. Because glass fiber contains oil and other compounds during the production process, it should be placed in ventilation. It can be used normally after a few minutes.
3. There is a squeak-squeak sound when the electric heating mantle above 3000ml is used. It is because the structure of the furnace wire is different and it is related to the thyristor voltage regulating pulse signal, which can be used with confidence.
4. When liquid spills into the sleeve, please turn off the power quickly, put the electric heating sleeve in a ventilated place, and use it after it is dry to avoid the danger of leakage or short circuit of the appliance.
5. When not used for a long time, please keep the electric heating jacket in a dry and non-corrosive gas place.
6. Please do not empty the heating or dry burning.
7. When the relative humidity is too high, induction power may be transmitted to the shell through the insulation layer. Please ground the cable and pay attention to ventilation.
