Place the stirring bar in the bowl and stir for about 30 min.

A small magnetic stir bar can be used to keep the particles in suspension.

Add 50 mL of kerosene and a magnetic stirring bar.

Gently add a small stir bar to each flask.

Most stir bars have a ridge around the center (called a pivot ring) on which they rotate.

A stir bar is the magnetic bar placed within the liquid which provides the stirring action.

Stir bars are typically coated in teflon, or less often in glass.

Because of its small size, a stirring bar is more easily cleaned and sterilized than other stirring devices.

Stir bars also have difficulty in dealing with viscous liquids or thick suspensions.

Remove the stirring bar, gently rinse off any cereal and look for small dark iron filings on the magnet.

It provides two independent magnetic fields, so two stir bars can be used at an adjustable separation.

Place a portion of the test sample in a clean glass beaker provided with a stirring bar or other suitable mixing device.

When ordering a Model 300 please specify the stirring heads and stirring bars appropriate to the application.

No additional stir bar required.

Finally rinse stirring bar with ethanol.

Stirring bars or other stirring devices suited for round-bottom flasks are sometimes used.

Remove magnetic stirring bar with non-magnetic tweezers.

Magnetic stirrer and stirring bar.

Magnetic stir bars are radial-flow mixers that induce solid body rotation in the fluid being mixed.

Magnetic Stirrer and stir bars.

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

A dry 50-mL flask equipped with a magnetic stirring bar and septum inlet was flushed with nitrogen.

Then rods were suspended with the tissue positioned 5 mm above stirring bars rotating at 1,200 rpm and uptake was measured for 2 min.

Magnetic stir bars work well in glass vessels commonly used for chemical reactions, as glass does not appreciably affect a magnetic field.

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.
