What does a magnetic stirrer do?

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.

Are Heating magnetic stirrer Velp?

Aluminum alloy top plate ensures an outstanding temperature homogeneity and optimum heat transfer across the entire surface, of up to 370 °C. Extremely intuitive control panel.

Is hot plate a stirrer?

A standard piece of laboratory equipment, the hot plate stirrer / hot plate magnetic stirrer keeps liquids circulating as they are heated for a faster, more even reaction.

Why would you use a stirrer bar?

These bars have only one purpose: to stir solutions. They are used in conjunction with a stir motor. You place the stir bar in a container of liquid, then place the container over a stir motor. When you turn the stir motor on, the bar spins and the liquid is stirred.

Is magnetic stirrer good?

Simply stated, a magnetic stirrer uses a rotating magnetic field to force a stir bar to rapidly spin. This stirs whatever liquid you may be working with at the time. Most often used for applications in chemistry and biology, magnetic stirrers are quiet, durable, and efficient.

Do I need a magnetic stirrer?

If you are mixing a low-viscosity liquid in higher volumes, an overhead stirrer is probably the right way to go. However, if your liquid is more viscous and you don’t need the extra capacity that overhead stirrers offer, a magnetic stirrer is a better choice since you don’t have to worry as much about overheating.

What is stirrer motor?

The primary function of the stirrer shaft is to transmit torque from the stirrer motor to the impeller. Torque is the tendency of a force to cause an object to rotate. The magnitude of the torque around the shaft axis is related to the power required for operation of the impeller.

What is a 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.

Who is a stirrer?

stirrer. / (ˈstɜːrə) / noun. a person or thing that stirs. informal a person who deliberately causes trouble.

What is inside a magnetic stirrer?

A magnetic stirrer consists of a magnetic bar placed within the liquid which provides the stirring action. The stir bar’s motion is driven by another rotating magnet or assembly of electromagnets in the stirrer device, beneath the vessel containing the liquid.

How does a magnetic stirrer work?

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