What is a magnetic stirrer used for?

A magnetic stirrer is used to mix liquids by creating a rotating magnetic field that causes a stir bar (flea) immersed in the liquid to spin. This provides efficient and consistent agitation without direct contact.

What type of vessels can be used with this stirrer?

Most standard laboratory glassware such as beakers, flasks, and bottles made of glass or suitable plastic can be used, provided they are compatible with the stir bar and the sample volume.

How do I choose the correct stir bar?

The choice of stir bar depends on the vessel size, liquid viscosity, and desired stirring intensity. It should be small enough to rotate freely without touching the sides or bottom of the vessel.

Is this unit suitable for continuous operation?

Many laboratory-grade magnetic stirrers are designed for extended periods of operation, but buyers should confirm specific duty cycles with the seller for this particular used unit.

What maintenance is typically required for a magnetic stirrer?

Routine maintenance usually involves keeping the stirring plate clean and ensuring the power cord is in good condition. There are generally no user-serviceable parts inside the unit.

Informazioni tipiche per questa categoria di macchinari. Verifichi sempre i dettagli con il venditore.

Laboratory mixing of liquid samples for chemical reactions or solution preparation.
Titration procedures requiring consistent agitation.
Biological sample preparation where gentle, uniform mixing is essential.
Quality control processes in various industries for sample homogenisation.

Typical stirring capacity: Units of this type commonly handle volumes up to 1-2 litres.
Speed range: Magnetic stirrers typically offer variable speed control, often ranging from 100 to 1500 RPM.
Plate material: The stirring plate is commonly constructed from stainless steel or ceramic for chemical resistance.
Power supply: For laboratory equipment in the UK, a standard 230V, 50Hz single-phase power supply is typical.
Footprint: Benchtop magnetic stirrers are generally compact, designed to occupy minimal laboratory space.
Heating function: While some models include heating, the SM1 is typically a non-heating stirrer, focusing solely on agitation.

Lab mixers and stirrers hold strong reputations for reliability and durability. Buyers typically prioritise motor condition, speed range suitability, and vessel compatibility when purchasing used units. The equipment category is valued for consistent performance across research and production settings. Key strengths include robust construction, straightforward maintenance, and long operational lifespans. Corrosion resistance of wetted parts merits careful inspection. These devices remain dependable workhorses in pharmaceutical, biotech, and laboratory environments, offering solid value when sourced from reputable sellers with clear service histories.
