Magnetic stirrers Magnetic stirrers without heating
Magnetic stirrers without heating are laboratory devices used to mix liquids by means of a rotating magnetic field that drives a stir bar located in the vessel. They are used wherever heating of the sample is not desired or not required. In this category you will find an overview of various models for different areas of application in the laboratory.

Magnetic stirrers without heating in everyday laboratory use
Operating principle
Magnetic stirrers without heating generate a magnetic field via a rotating drive magnet, which sets a stir bar in the sample vessel in motion. This homogenizes liquids or dissolves substances without any additional change in temperature taking place.
Areas of application
Devices in this category are used when samples or reagents need to be mixed without introducing heat into the process. This is particularly relevant for temperature-sensitive or thermolabile substances, where heating could distort the result.
Difference from heatable magnetic stirrers
Unlike magnetic stirrers with a heating function, the devices in this category do not have an integrated heating plate. They are limited to the pure stirring function and are therefore suitable for applications where temperature constancy or sensitivity to cold is the primary concern.
Selection criteria
When choosing a suitable magnetic stirrer without heating, users should pay attention to factors such as vessel size, stirring volume, and the intended environment of use in the laboratory. The specific technical data of the individual models can be found in the respective product descriptions.
What is a magnetic stirrer without heating?
It is a laboratory device that mixes liquids using a rotating magnetic field and a stir bar, but operates without an integrated heating function.
How does a magnetic stirrer without heating basically work?
A drive motor generates a rotating magnetic field that sets a magnetic stir bar in the vessel in motion, thereby mixing the liquid.
In which areas are magnetic stirrers without heating used?
They are used wherever samples or solutions need to be mixed, but heating of the medium is to be avoided.
What is the difference to heatable magnetic stirrers?
Unlike heatable variants, magnetic stirrers without heating do not have an integrated heating plate and are limited exclusively to the stirring function.
What role does the stir bar play?
The stir bar is the magnetic element that is driven by the device's rotating field and causes the actual mixing in the vessel.
Can magnetic stirrers without heating be used with temperature-sensitive samples?
Since no heat is introduced into the stirring process, these devices are generally suitable for applications where a change in temperature should be avoided.
What should be considered when selecting a magnetic stirrer without heating?
Users should take into account vessel size, required stirring volume, and the technical specifications of the respective model in order to choose a suitable device for the intended use.
