• Titration procedures requiring consistent agitation.

Typical stirring capacity

For this class of equipment, units typically handle volumes ranging from a few millilitres up to several litres, commonly around 1-5 litres.

Power supply

Units of this type commonly operate on standard laboratory mains power, typically 230V, 50/60Hz in the UK.

Stirring speed range

Magnetic stirrers in this category typically offer a broad speed range, often from 100 to 2000 rpm, allowing for precise control.

Number of stirring positions

The 'MIX 1' designation suggests a single stirring position, which is common for individual laboratory tasks.

Control type

The 'MIXcontrol 20' model implies an external control unit, providing precise and often programmable stirring parameters.

Maintenance requirements

Magnetic stirrers are generally low-maintenance, with no moving parts in contact with the sample, often described as 'maintenance-free' for the stirring drive itself.
