This mini magnetic stirrer is a compact 10 x 10 x 3cm base that spins a magnetic stir bar at 200 to 2000 rpm, with the speed set by a single knob. The same knob switches the unit on and off, and the speed is adjusted steplessly rather than in fixed steps. The plug-in version runs from a 5V USB interface, and a magnetic stir bar measuring 2.5 x 0.8cm is included.
Features and benefits:
- 200 to 2000 rpm speed range - slow swirling for light mixes and fast stirring for thinner liquids
- Stepless speed dial with markings at 600, 1200 and 2000 plus OFF - set the speed you want rather than choosing from fixed steps
- One knob for power and speed - turn it from OFF to start, no separate switch to hunt for
- Built-in magnetic drive - the stir bar is turned by the magnet in the base, so no shaft or paddle enters the vessel
- Small 10 x 10 x 3cm body - fits on a crowded bench and is easy to move between workstations
- ABS material - lightweight casing
- 2.5 x 0.8cm stir bar supplied - ready to use with a suitable beaker
Applications:
- Mixing solutions in school and college science lessons
- Dissolving powders in water or other liquids on the workshop bench
- Stirring small batches in food, cosmetics and brewing work
- Light laboratory mixing in measuring cups up to 500ml
In the box:
- 1 x magnetic stirrer base
- 1 x USB-A to Type-C cable, 1m
- 1 x magnetic stir bar, 2.5 x 0.8cm
Note: A beaker is not included. Use it only with vessels up to 500ml. Thick liquids slow the rotation and can stop the stir bar from turning, so keep to thin and medium viscosity liquids. This unit has no heating function. It is a stirrer only, not a hotplate.

A: A magnet inside the base spins under the vessel and drags a magnetic stir bar around inside the liquid. This stirrer uses a built-in magnetic drive to turn the 2.5 x 0.8cm stir bar at 200 to 2000 rpm.. Q: How do you use a magnetic stirrer? A: Drop the stir bar into a beaker or measuring cup of liquid, stand it on the base and plug in the USB cable. Turn the knob from OFF and raise the speed until the stir bar spins steadily.. Q: Does this magnetic stirrer have a heater? A: No. It is a stirring base only, with a speed dial and no heating element. If you need a hotplate with magnetic stirring, choose a unit that lists a heating function.. Q: What size beaker can I use? A: The maker states it is suitable only for measuring cups within 500ml. Use a flat bottomed vessel that sits level on the base.. Q: Why does the stir bar stop turning in thick liquids? A: Thicker liquids reduce the rotation speed and can prevent the rotor from stirring. Keep to thinner liquids or lower the volume if the bar stalls..
