Protective cover for magnetic stirrers

Quick Answer: The Protective Cover for Magnetic Stirrers is a clear, flexible cover moulded to the shape of a magnetic stirrer’s housing, with openings for the control knobs. It keeps spills, splashes and dust off the stirrer while leaving the controls usable and the stirring surface available for the vessel.

How the Cover Protects a Stirrer

Magnetic stirrers spend their lives under beakers of liquid, and sooner or later something overflows. Liquid that runs down the housing reaches seams, knob shafts and ventilation openings, where it can damage the electronics or corrode the drive. A moulded protective cover for magnetic stirrers gives that liquid somewhere harmless to go.

The listing photograph shows a translucent, flexible cover shaped to fit over a stirrer: a flat top with a round area where the vessel stands, a sloping front, and two round openings on the front for the control knobs. The clear material lets the user see markings and the stirring position through the cover, and the whole cover can be lifted off and rinsed.

The title refers to magnetic stirrers in general, not to a particular model, and covers of this kind are shaped for specific housings. Heating stirrers raise another point: if the top plate area is covered, the cover must be rated for the plate temperature before heating is used. For Guardian units, a dedicated Guardian protective case is listed separately.

Specifications

Applications

• Protecting stirrers used by students preparing solutions
• Stirring culture media or buffers that tend to foam and overflow
• Keeping stirrers clean in dusty or shared work areas
• Extending the life of a heating magnetic stirrer used mainly for stirring

Care & Handling

• Use the cover only with stirrers it is shaped for
• Do not use heating under the cover unless its temperature rating allows it
• Rinse the cover with water and mild detergent and dry it before refitting
• Replace a cover that has split or become cloudy and stiff

Schools and teaching labs buy protective covers so shared stirrers survive years of student use. LabEquip can check which stirrer housings the cover fits and supply it from our general lab products range; contact us with your stirrer model.

Frequently Asked Questions

What does a protective cover for magnetic stirrers do?

It covers the housing and controls so spills and splashes do not get into the stirrer’s electronics or drive, while the stirrer keeps working.

Can I use the stirrer with the cover on?

Yes. The photographed cover has openings for the control knobs and a flat top where the vessel stands, so the stirrer can be used normally.

Can I use the cover on a heating stirrer?

Only if the cover is rated for the plate temperature. If in doubt, use it with heating switched off, or choose a cover that leaves the hot plate uncovered.

Does the cover weaken the stirring?

Where the cover lies over the stirring surface, it adds only a little distance between the magnet and the stir bar, so stirring is usually unaffected at normal speeds.

Which stirrers does the cover fit?

Covers are shaped for particular housings, and the listing does not name one. Tell us your stirrer model and we will confirm the fit.

How do I clean the cover?

Lift it off, rinse it with water and a mild detergent, dry it and refit it. Avoid strong solvents, which can cloud or soften flexible plastics.
