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, providing agitation.

How do I choose the right size stir bar?

The appropriate stir bar size depends on the volume and viscosity of the liquid being stirred, as well as the dimensions of the vessel. A longer stir bar generally provides better mixing for larger volumes.

Can this unit heat samples?

The Stuart Scientific SM1 is a basic magnetic stirrer and does not include a heating function. For heated stirring, a hotplate stirrer would be required.

What maintenance is required for a magnetic stirrer?

Maintenance is generally minimal, involving regular cleaning of the stirring plate to prevent contamination and ensuring the power cord is in good condition. No internal user-serviceable parts are typically present.

Is this unit suitable for continuous operation?

Many laboratory magnetic stirrers are designed for extended periods of operation, but it is advisable to consult the manufacturer's guidelines for specific duty cycles.

Типичные сведения для этой категории оборудования. Всегда уточняйте детали у продавца.

Laboratory mixing of liquid samples for chemical reactions or solution preparation.
Titration procedures requiring consistent agitation.
Dissolving solids into liquids for analytical or preparative chemistry.
Biological sample preparation where gentle, uniform mixing is needed.

Typical stirring capacity: Units of this type commonly handle volumes up to 1-2 litres, depending on viscosity.
Speed range: Magnetic stirrers typically offer variable speed control, often ranging from 100 to 1500 rpm.
Plate material: The stirring plate is commonly made from chemical-resistant materials such as stainless steel or ceramic.
Footprint: For this class of equipment, a compact footprint is typical, often around 150-200mm square.
Power supply: These units typically operate on a standard UK mains supply (230V, 50Hz).
Motor type: Most laboratory stirrers utilise a DC motor for reliable and consistent stirring.

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.
