magnetic stirrer

Magnetic stirrers may also include a hot plate or some other means for heating the liquid.

Magnetic stirrers are often used in chemistry and biology.

The reaction can also be performed in a beaker using a magnetic stirrer.

On the other hand, the limited size of the bar means that magnetic stirrers can only be used for relatively small (under 4 liters) experiments.

This could be accomplished with a magnetic stirrer and accompanying magnetic stir bar.

Stir on magnetic stirrer until calcium sulfate is dissolved, add to the 19 L above, and mix well.

Some hot plates also contain a magnetic stirrer, allowing the heated liquid to be stirred automatically.

For example, the surroundings can do work through a changing magnetic field that rotates a magnetic stirrer within the body.

Using glass beads or a magnetic stirrer or carefully warming to 37 degrees C may help in dissolving.

At a laboratory scale, mixing is achieved by magnetic stirrers or by simple hand-shaking.

Heidolph magnetic stirrers are used for smooth to intense mixing of low-viscosity fluids.

Agitate the cells and tubule fragments using a stirring bar and magnetic stirrer for about I h.

Shakers have largely been replaced by magnetic stirrers for many purposes, but are still favoured for some situations, such as those involving large volumes.

Overhead Stirrers, not to be confused with magnetic stirrers, are used for standard mixing of the higher viscosity substances.

Only someone who knows about a magnetic stirrer, used in laboratories to mix solutions, could create a tornadolike vortex in a glass jar filled with water.

After negotiating ideas, Mr. Lafler created a glass bulb with a glass fan that could be turned with a magnetic stirrer.

The first multipoint magnetic stirrer was developed and patented by Salvador Bonet of SBS Company in 1977.

The stands are usually made of a chemically impervious metal and may be covered with aluminium foil to further protect the base, on which may sit a hot plate, magnetic stirrer, heating mantle, or some other apparatus.

A magnetic stirrer or magnetic mixer is a laboratory device that employs a rotating magnetic field to cause a stir bar (also called "flea") immersed in a liquid to spin very quickly, thus stirring it.

MR Hei- Standard and MR Hei- End are a few models of the magnetic stirrer line where you can set the amount of heat and speed required for substance manipulation.

The mixture is put into the round bottomed flask along with a few anti-bumping granules (or a Teflon coated magnetic stirrer bar if using magnetic stirring), and the fractionating column is fitted into the top.

High corrosion resistance favors the use of PTFE in laboratory environments as containers, as magnetic stirrer coatings, and as tubing for highly corrosive chemicals such as hydrofluoric acid, which will dissolve glass containers.

The unit automatically controls the injections of the various constituents into 5ml test-tubes, agitates them with a magnetic stirrer, and detects whether they are clear, cloudy or opaque in the near infra-red region over the whole length of the test-tube.
