Benchtop units Magnetic stirrers
Magnetic stirrers create a rotational movement of the stir bar within a vessel via a rotating magnet in the device base—a contact-free, contamination-free method for mixing liquids. They are the standard instrument for buffer preparation, solution formulation, and homogeneous mixing of chemical reactions in the laboratory.

Guardian 2000 magnetic stirrers: with and without heating
Magnetic stirrers create a rotational movement of the stir bar within a vessel via a rotating magnet in the device base—a contact-free, contamination-free method for mixing liquids. They are the standard instrument for buffer preparation, solution formulation, and homogeneous mixing of chemical reactions in the laboratory.
Magnetic stirrers without heating
The Guardian 2000 models without heating function (e-G21ST07R, 376.00 €, e-G21STRDS, 339.00 €) are the right choice for mixing at room temperature—such as for buffer solutions or reagent preparations that do not require temperature control.
Magnetic stirrers with heating
The Guardian 2000 models with heating function (e-G21HS07C, 437.00 €, e-G21HSRDS, 394.00 €) combine magnetic stirring with simultaneous temperature control—necessary when a mixture must be heated during stirring, such as when dissolving poorly soluble substances or for temperature-dependent reactions.
Frequently asked questions about magnetic stirrers
The most important questions regarding the choice between models with and without heating function.
Do I need a magnetic stirrer with a heating function?
A heating function is necessary if the solution is to be heated during stirring—for example, to dissolve poorly soluble substances more quickly or for temperature-dependent reaction mixtures. For pure mixing at room temperature, a model without heating is sufficient.
What is the difference between a magnetic stirrer and a laboratory shaker?
A magnetic stirrer mixes liquids in a vessel via a rotating magnetic stir bar—suitable for homogeneous solutions. A laboratory shaker moves the entire vessel or multiple vessels simultaneously and is also suitable for suspensions or multiple samples in parallel.
Which vessel sizes are compatible with the Guardian 2000?
The exact maximum stirring capacity is model-dependent and specified in the respective product data sheet. For larger volumes or special vessel shapes, we are happy to advise on the appropriate model selection.
