Press the “Parameter Increase Key” setting value to increase. If the fiberglass is brittle or cracked or if any wires are exposed, discard the heating mantle. For the most common form, the heating element (electric wires) is embedded within a strip of fabric, generally fiberglass, forming a "nest" or "basket", where the container can be placed. There is a rubber plug on the lower left side of the electric heating mantle, which is used to maintain the external thermocouple socket without corroding rust and turning on the inner wire. To prolong the life of your heating mantle, clean up spills (solid or liquid) right away.
Price varies depending on the brand, type and complexity.
Press the setting the increase“▲” or setting the minus “▼” button will quickly set the required heating temperature: 100℃, the green light on indicates warming, and the red light off indicates stop. Plug in 220V power supply, and turn on the power switch. If the external thermocouple is used, the plug should be unplugged. When the temperature is raised to the desired temperature or the solution is boiled, the knob can be lowered to heat the insulation to prolong the service life. Touching this device and ground at the same time could complete a circuit with your body and lead to electrocution. As they do not glow when hot, it is difficult to know how hot they are.
Regardless of the method you use to heat something, a stuck contact, an electrical short circuit, runaway chemical reaction, or other malfunction can cause a reaction to heat to dangerously high temperatures. When the thermocouple is poorly connected, the display window displays “1” or “hhhh” on the hundredth position, the green light is off, and the electric appliance stops heating, and needs to be viewed and used again. When using it, it should be prevented from correcting the correct display to incorrect. http://www.sciencemadness.org/smwiki/index.php?title=Heating_mantle&oldid=11170, GNU Free Documentation License 1.3 or later, Heating mantles can achieve higher temperatures than most heating devices. Except for the cord, mantles are not generally repairable. Heating mantles can be made by wrapping a heating tape in a hemispherical shape and placing it in a metal or ceramic container. The green light indicates the power, while the red light indicates the heating. As a kind of heating instrument commonly used in laboratories, a electric heating mantle can reduce the heating time of experimental objects and reduce the consumption of energy. Press and hold the increase key or decrease the key set value to change rapidly. Single-button operation. Which Domestic Rotary Evaporator is of Good Quality and Cost-Effective, Operation Procedures of Short Path Molecular Distillation, What are the troubleshooting of vacuum pump. Turn off the power when it is not in use for a long time.
A good tip is to hold a piece of glass over the basket, which will cause water vapor to condense on the glass if it's still hot.
Heating Mantle Types.
Due to the fixed shape of the heating basket, only flasks of exact volume or very close volume can be used, Since the heating element (heating basket) is exposed, any spills can damage the device, Heating mantles are very useful for distillations that require high temperatures, such as the distillation of. Press the “Parameter Set Key” again to return to the normal working state and the temperature setting is completed. There are many types of heating mantles.
For after hours, weekends, and holidays, please contact the Department of Public Safety at 501-916-3400. Sensor error correction: The display value can be corrected when the value displayed on the meter is not the correct measurement value.Press the “Parameter Setting Key” for 3 seconds to enter the inner menu. Your email address will not be published. When the instrument is shipped, the correction value is 0.
The one on the left has a shell that supports the flask, the middle one has a hemispherical outer aluminum shell, and the one on the right has a flexible all-fiberglass design. When it is not in use for a short time, turn the knob to 0 to stop warming. One of the most popular and safest methods to heat a reaction mixture is a heating mantle, a resistively heated flexible fiberglass shell that conforms to the shape of the reaction flask. 26 Jan. As a kind of heating instrument commonly used in laboratories, a electric heating mantle can reduce the heating time of experimental objects and reduce the consumption of energy. Most heating mantles are hemispherical in design and come in a variety of sizes designed to fit round bottom flasks from 50 mL up to 5000 mL or more.

Although heating mantles aren't illegal per see, in some places their purchase may be monitored. Diy heating mantle, aka the coffee can heating mantle. Press the “Parameter Decrease Key” to decrease the value.
Many common purification, catalysis, decomposition and other experiments require the use of electric heating mantles to heat and catalyze the reaction, so that the experiment can be better implemented. Heating tapes may also be used to keep distillation columns warm or to regenerate catalyst columns. The operation is as follows. heating mantle uses How to Use a Electric Heating Mantle Correctly. Never immerse a heating mantle in water or other liquids (or place these in the mantle), and always use a properly grounded outlet.
Shown below are three examples of heating mantles. The current supplied to the device is regulated by a rheostat, generally attached on the outside of the co… Then how to use a electric heating mantle correctly and efficiently? I have divided the use of electric heating mantles into four aspects in detail through comprehensive arranging. Fires and explosions can often result from the heating of chemical reaction mixtures. I hope that you can refer to these four aspects and learn how to use electric heating mantles correctly. The external thermocouple plug is inserted into the socket and the nut is locked, and then the stainless steel probe is placed in the solution for temperature control heating.
If you want to know more about electric heating mantles, or if you want to buy them, please contact Henan Lanphan Industrial Co., Ltd. We will be happy to help you, our email address is [email protected], ZNHW-II Intelligent Digital Heating Mantle, TWCL-T Thermoregulation Magnetic Heating Mantle, ZNCL-T Single Digital Dispaly Magnetic Heating Mantle, ZNCL-TS Double Digital Display Magnetic Heating Mantle, Your email address will not be published. Adjusting the knob clockwise, the temperature will rise gradually. Less tendency to generate harmful hotspots.
This page was last modified on 11 May 2019, at 21:05. Some heating mantles also have magnetic stirring function. In US, the sale of all heating mantles with a volume of 22 liters (5.8 US gallons) are monitored. This parameter can be modified by selecting the parameter Sc followed by the “parameter increase key” or “parameter decrease key”.The correction range of the sensor error is +50 ° C to -50 ° C. After the correction is completed, press the “Parameter Setting Key” for 3 seconds to exit.
