To directly control the temperature of liquid in a vessel on the top surface, place the External Temperature Controller into the liquid and connect the Controller to the product. The Heating Temperature Display shows the temperature of the liquid and can be used to adjust the temperature of the liquid.
Moreover, how do you know that the heat setting on the hot plate stirrer is on?
Temperature indicator (heating type) The “Heat” light is lit when the heating function is turned on . Stirring indicator The “Stir” light is lit when the stirring function is turned on . Residual heat warning indicator The red light is on when the temperature exceeds 50 °C .
Secondly, how do you use a magnetic stirrer hot plate?
To use the magnetic stirrer:
Turn on the magnetic stirrer by flipping the power switch on (–), then rotating the left knob in a clockwise direction. 3. The farther you rotate the knob, the faster it will spin to stir your solution. You can control the stirring speed between about 120 and 1400 rpm.
How does a hot plate stirrer work?
The magnetic stirrer creates a rotating field based on a rotating magnet bar or a plate containing the rotating magnet. In general, the bar magnet is coated with plastic and plate contains a rotating magnet. … The main function of a stirrer is to agitate the liquid for speeding up the reactions or improving mixtures.
How does a stir bar work?
How does it work? A stir bar magnet is placed inside a container, immersed in the fluid. A separate magnet (or magnets) is placed underneath the container, so that it attracts to the stir bar magnet. … If the magnets are close enough, the stir bar magnet spins inside the container.
How hot can hot plates get?
Typical operating temperatures vary from 100 to 750°C and power requirements are usually in the 120 to 480 volt range. Most industrial hot plates will withstand loads more than 150 pounds. Industrial hot plates which incorporate a porous heated plate are referred to as heated chucks.
What does the hot plate represent?
heats the ocean before evaporation. If water was heated in an experiment by a hot plate to model the water cycle, the hot plate represents… the sun.

What is a magnetic stirrer used for?
A magnetic stirrer is a device widely used in laboratories and consists of a rotating magnet or a stationary electromagnet that creates a rotating magnetic field. This device is used to make a stir bar, immerse in a liquid, quickly spin, or stirring or mixing a solution, for example.
What is hot plate stirrer?
The hotplate stirrer (or hot plate stirrer or hot plate magnetic stirrer) is used for mixing and heating aqueous solutions for a great variety of chemical reactions such as synthesis.
What is the function of hot plate in microbiology?
Hot plates are frequently used in the laboratory to perform chemical reactions, to heat samples, and for numerous other activities. Hot plates are conceptually simple – a flat surface with heating elements. They do not produce open flames and are well suited for oil or sand bath use.
What is the role of the hot plate Why is it important?
Hot plates are laboratory tools used to uniformly heat samples. Hot plates provide less heat, but do so without the danger associated with the open flame and higher temperatures of a Bunsen burner. Hot plates often include digital displays of temperature, hot surface warning indictators and magentic stirrers.
What is the rotational speed of hot plate stirrer?
Available Range :
| Mode | Digital + Heating + Stirring |
|---|---|
| Minimum revolution | 200 rpm |
| Heating plate | SS with Ceramic coating |
| Driving mode | Motor |
| Stir bar | PTFE |
Why are hot plates important?
The hot plate is a vital device that is used in a laboratory to heat samples. The fact that it has the ability to heat the sample without any exposed flames is one of the major advantages. It is a device that can be used on a daily basis for temperatures as high as 100 degrees and even higher.
