Firstly, the Thermo Scientific Cimarec i Maxi Direct is a digital inductive-drive magnetic stirrer with integrated controller for general laboratory applications. Moreover, this model combines a powerful magnetic coupling system with a hermetically sealed stainless steel housing. As a result, the unit is suitable for sample volumes up to 5 liters and chemically aggressive environments. In addition, the Maxi Direct offers a unique wide stirring range from just 80 rpm up to a maximum of 2000 rpm. The series was previously sold under the name Variomag.
Firstly, the Cimarec i Maxi Direct features a built-in microprocessor controller with bright digital display. Secondly, you do not need to connect an external controller, which keeps the bench clear. In addition, the unit remembers the last used settings for quick repetition of protocols. Moreover, the gradual start acceleration offers smooth coupling that prevents splashing.
Firstly, you can set the power independently of the speed between 5, 10, 15 or 20W. Secondly, you choose the minimum power required to maintain the desired stirring speed. In addition, this means lower energy consumption and less heat dissipation to your sample. Moreover, this is ideal for temperature-sensitive applications where heat input must remain minimal.
Firstly, the IP64 protection class offers resistance to dust and water splashes from all sides. Secondly, you can easily clean the unit with running water. In addition, the stainless steel housing resists aggressive chemicals such as acids, alkalis and organic solvents. Moreover, the hermetically sealed design offers protection against moisture and microorganisms.
The Cimarec i Maxi Direct magnetic stirrer is widely used in the pharmaceutical industry and biotech, medical diagnostics, food industry and agriculture and horticulture. For advice, please contact Poly Temp Scientific.

Firstly, the Thermo Scientific Cimarec i Maxi Direct is a digital inductive-drive magnetic stirrer with integrated controller for sample volumes up to 5 liters. In addition, this model offers a wide stirring range of 80 to 2000 rpm, four power settings up to 20W and a hermetically sealed stainless steel housing with IP64 protection. Moreover, the Maxi Direct is ideal for general laboratory applications where precision and durability are important.








The Cimarec i Maxi Direct magnetic stirrer is designed for general laboratory applications with sample volumes up to 5 liters where an integrated controller is desired. Moreover, this model is ideal for applications requiring precise digital speed control. In addition, the chemically resistant stainless steel housing makes it suitable for mixing aggressive media in pharma, biotech, food industry and general chemical laboratories.
With an integrated controller you have all operating elements directly on the stirrer, which saves bench space. Secondly, you do not need to connect or store an extra external controller unit. In addition, the settings are directly visible via the digital display. Moreover, this setup is ideal for users who do not need to control multiple stirrers in parallel.
The Mono Direct is an analog stirrer with rotary knob, a speed range of 130 to 1200 rpm and IP32 protection. Secondly, the Maxi Direct offers digital microprocessor control with display, a wider speed range of 80 to 2000 rpm and IP64 protection. In addition, the Maxi Direct has four power settings up to 20W versus two settings on Mono Direct. Moreover, the Maxi Direct handles larger volumes up to 5 liters compared to 3 liters on Mono Direct.
Firstly, you can set the power to the minimum level required to maintain the desired stirring speed. Secondly, this means lower energy consumption during long experiments. In addition, the device produces less heat, which is ideal for temperature-sensitive samples. Moreover, you prevent unnecessarily heavy coupling for light mixing tasks, which keeps the stir bar more stable in position.
IP64 means the unit is fully protected against dust (IP6X) and resistant to water splashes from all sides (IPx4). Secondly, you can easily clean the stirrer with running water without damaging the electronics. In addition, this is sufficient for applications with spills or in humid laboratory environments. Moreover, this is less demanding than the IP68 protection of the Compact and Maxi stirrers, which are fully submersible.
