What is a stirrer used for?

What is a stirrer used for?

The main function of a stirrer is to agitate the liquid for speeding up the reactions or improving mixtures. A magnetic stirrer is often used with hot plates. The stir bar is the magnetic bar which is immersed in the liquid to provide the stirring action.

How do you use a hot plate stirrer?

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 an electric stirrer work?

The electromagnetic stirrer utilizes the principle of a linear motor and differs from the conventional mechanical and decompression types as it is a noncontact stirrer in which no part touches the molten metal. As this thrust moves in the direction of the moving magnetic field, the molten metal also moves.

What is coffee stirrer?

Coffee stirrers go far beyond those little wooden sticks you collect from next to the sugar packets when you grab a coffee to go. This includes alternatives to the classic plastic or wooden stirrer and stylish stirrers for gifts or parties. Find frothers to froth milk for lattes, cappuccinos or hot chocolates.

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.

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.

Can a heating plate be used as a stirrer?

With the use of heating plates, you can mix a wide variety of samples for different applications. Aside from magnetic stirrers, you may also mix your samples using motor power overhead stirrers. While overhead stirrers can handle larger volumes of fluid, they aren’t suitable for all viscosity levels.

What is the stirring function of a stirrer?

In general, there are two magnetic stirrer function s: heating and stirring. The stirring function of magnetic stirrer: 1.To uniformly mix the reaction material and balance temperature distribution, in order to speed up reaction or evaporation, then shorten reaction time;

How does a magnetic stirrer work in a stirrer?

Magnetic stirrers use a rotating magnetic field to move a stir bar around in liquid samples, and some are coupled with stirring hot plate. The movement of this stir bar mixes the samples thoroughly with rapid movement and agitation. The user controls the magnetic field’s speed, so it can be customized to the specific sample that’s being stirred.

What is the temperature of a hot stirrer?

The dual controls allow you to set heat output and stirring speed independently. The hot plate reaches a temperature of over 250°C (480°F) with an output of 180 watts. The magnetic stirrer is adjustable from 0 to up to about 1400 rpm and suitable for mixing up to 500ml of solution in a container of 5” diameter or less.
