Magnetic stirrer with thermometer stand

Magnetic stirrer with thermometer stand and teflon stirrer.

A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field. The reason is to cause a stir bar immersed in a liquid to spin very quickly, thus stirring it. The rotating field may be created either by a rotating magnet or a set of stationary electromagnets, placed beneath the vessel with the liquid. It is used in chemistry and biology where other forms of stirring, such as motorized stirrers and stirring rods, may not be viable for use.

Available in two sizes

Easy to use

Stepless speed adjustment 100-2000 rpm

220V/50Hz

OPERATION

1.Put the machine on worktable, and switch on power

2.Turn on the stirring power clockwise and set rotating speed as needs.

Keep it in dry and clean room.

A heating element, whose power may range from a few hundred to a few thousand watts, can also be incorporated to the stirrer to allow the reaction flask to be heated and stirred at the same time. The maximum reachable fluid temperature depends on the size of the flask, the quantity of solution to be heated, and the power of the heating element.

Because of its small size, a stirring bar is more easily cleaned and sterilized than other stirring devices. They do not require lubricants which could contaminate the reaction vessel and the product. Magnetic stirrers may also include a hot plate or some other means for heating the liquid.

A stir bar retriever is a separate magnet on the end of a long stick (usually coated with PTFE) which can be used to remove stir bars from a vessel.
