What is a magnetic stirrer used for?

A magnetic stirrer is used to mix liquids or dissolve solids in liquids by creating a rotating magnetic field that causes a stir bar (flea) immersed in the liquid to spin.

Does this unit come with a stir bar?

Stir bars are typically consumable items and are often sold separately. Buyers should confirm with the seller if any accessories, such as stir bars, are included.

Is this stirrer suitable for continuous operation?

Many laboratory magnetic stirrers are designed for continuous or extended operation, but buyers should consult the manufacturer's specifications for specific duty cycle recommendations for this particular unit.

What maintenance is required for a magnetic stirrer?

Maintenance is generally minimal, primarily involving keeping the unit clean and ensuring the power cord is in good condition. No specific internal user-serviceable parts are typically present.

Can this stirrer be used in a fume hood?

Yes, its compact size and chemical-resistant housing typically make it suitable for use within a fume hood, provided it meets local safety regulations and ventilation requirements.

This listing is for the Hanna HI190M Magnetic Stirrer.

The unit is in full working condition and is ready for immediate use.

The Hanna HI190M is a compact and durable magnetic stirrer designed for efficient mixing in constrained lab spaces.

Key Features:

Compact & Lightweight Design.
The device measures approximately 120 × 120 × 45 mm (4.8 × 4.8 × 1.8 in) and weighs between 610 g (12 V DC version) and 640 g (115 V version).
Its small footprint helps free up valuable bench space.
Speedsafe™ Safety Mechanism.
This smart system prevents dangerous overspeed when the stir bar is suddenly removed, using an opto-sensor and a frequency-voltage converter to monitor and limit speed.
Adjustable Speed Range.
Offers stirring speeds from 100 to 1000 RPM, providing precise control over mixing.
Durable Housing.
The ABS plastic casing resists many chemical spills, enhancing longevity and safety.
Power Indicator LED.
A handy LED lets you know at a glance that the unit is powered on and operating.
