Magnetic stirrer 1 L HI190M

The StemAids Magnetic Stirrer 1 L HI190M Hanna Instruments is a compact, reliable, and easy-to-use laboratory magnetic stirrer designed for routine sample mixing, solution preparation, and electrochemistry measurements. It is suitable for schools, colleges, research labs, quality-control labs, water testing labs, industrial laboratories, and general scientific applications.

This mini magnetic stirrer is ideal for users who need consistent stirring without a heating function. Its compact footprint saves valuable bench space, while the adjustable speed control allows users to regulate mixing speed according to sample requirements. Hanna notes that stirring helps produce a more homogeneous sample and can support faster sensor stabilization during electrochemistry measurements.

Product Description

The StemAids Magnetic Stirrer 1 L HI190M is supplied as a StemAids-listed laboratory product based on the Hanna Instruments HI190M magnetic mini-stirrer model. It is designed for mixing liquid samples up to 1 litre using a magnetic stir bar.

The stirrer features a durable ABS plastic cover that helps resist the harmful effects of accidental chemical spills. Its user-adjustable speed control makes it suitable for routine lab procedures where steady, controlled stirring is required. The built-in Speedsafe™ mechanism helps prevent the motor from exceeding the maximum speed, even if the load is suddenly removed.

This product is a good choice for pH testing, conductivity testing, titration preparation, water analysis, chemical solution mixing, classroom demonstrations, and general laboratory sample preparation.

How to Use

1. Place the magnetic stirrer on a clean, dry, flat, and stable laboratory bench.
2. Confirm that the power supply voltage matches your local electrical supply.
3. Place the liquid sample in a suitable beaker or laboratory vessel. Do not exceed the 1 litre stirring capacity.
4. Add a clean magnetic stir bar into the liquid sample.
5. Place the beaker at the center of the stirrer platform.
6. Switch on the unit and begin at a low speed.
7. Gradually increase the speed until a stable vortex or smooth mixing action is achieved.
8. Avoid setting the speed too high for viscous samples or shallow liquid volumes.
9. After use, reduce the speed, switch off the stirrer, remove the vessel, and clean any spills immediately.
10. Store the stirrer in a dry, clean location away from moisture, corrosive vapors, and excessive heat.
