The Thermo Scientific Cimarec Power Direct magnetic stirrer is engineered for laboratories and pilot plants where large volumes require reliable stirring. Moreover, the model combines powerful magnetic coupling with a compact, robust design that integrates easily into process setups. In addition, the integrated controller enables direct operation without external modules, simplifying both installation and maintenance.
This magnetic stirrer suits a broad range of applications involving large volumes or viscous media. Specifically, the unit delivers enough torque to keep liquids up to 40 liters consistently in motion, even at higher viscosity. Furthermore, the low profile (just 35 mm high) allows placement under existing equipment or within process installations.
The integrated controller offers four adjustable power levels (5, 10, 15, and 20 watts), which allows energy consumption and heat output to be tuned to the application. As a result, the working environment stays cooler while unnecessary power draw is avoided. In addition, the Quick Stop function reduces after-run behavior: when activated, the system halts the magnetic drive within two seconds. Notably, the IP22 protection class also provides resistance against falling water and small particles.
The Cimarec Power Direct features a sealed stainless steel housing that resists chemicals and cleans easily. Therefore, this model fits laboratories where regular cleaning and hygiene matter. Moreover, the absence of moving parts on the outside ensures minimal wear and a long service life. Furthermore, the operating temperature range extends from -10 to +40 °C, covering most laboratory environments.

The Thermo Scientific Cimarec Power Direct is a laboratory magnetic stirrer designed to handle volumes up to 40 liters. Specifically, the integrated controller delivers a speed range of 100 to 2000 rpm, adjustable across four power settings of 5, 10, 15, and 20 watts. Furthermore, the Quick Stop function halts the drive within two seconds, which minimizes after-runs and reduces breakage risk. As a result, this model suits viscous liquids and large volumes in pilot plants or integrated process installations.








A high capacity magnetic stirrer is a stirring unit designed to handle large volumes, typically from 20 liters upward. Specifically, these models deliver more magnetic torque than standard benchtop units, which is required for consistent mixing in large beakers, vessels, or process installations. Furthermore, such units often feature adjustable power settings to tune energy consumption to the application.
The Cimarec Power Direct stirs liquids up to a maximum of 40 liters. As a result, this model suits pilot plants, process installations, and laboratory applications where large volumes must be kept consistently in motion. In addition, the unit operates with a speed range of 100 to 2000 rpm.
A magnetic stirrer uses a rotating magnetic field to drive a magnetic stir bar inside the liquid. By contrast, a mechanical stirrer uses a physical shaft with an impeller that moves through the liquid. Therefore, magnetic stirrers suit sealed or sterile systems best, whereas mechanical stirrers are preferred for highly viscous media or volumes beyond the capacity of magnetic units.
The Quick Stop function halts the magnetic drive within two seconds after activation. As a result, the after-run behavior of the stir bar is significantly reduced, which lowers the risk of glassware breakage or sample damage. Moreover, this function speeds up workflow when the stirrer needs to be switched off quickly.
The Cimarec Power Direct fits applications involving large volumes or viscous media that require reliable stirring. For example: preparation of buffers and solutions at pilot plant scale, integration with process installations, suspensions in pharmaceutical development, and biotech workflows. Furthermore, the low profile allows placement under existing equipment or within process setups.
