Overhead Stirrer RW 20: Performance and Precision for Laboratory Environments

The RW 20 by IKA is an innovative overhead stirrer that stands out for its technical improvements over previous models in the RW 20 series. Designed to meet the demands of laboratory and medical environments, the RW 20 combines power, precision, and ergonomics, making it an indispensable tool for a wide range of mixing applications.

The RW 20 is equipped with a powerful motor with constant power drive, delivering reliable performance even under heavy loads. With its wide speed range of 60 to 2000 rpm, this stirrer easily adapts to various types of mixing processes. Its capacity to handle volumes of up to 20 liters (H₂O) makes it an ideal choice for large batch preparations, while maintaining precise and stable control.

One of the main advantages of the RW 20 is its clear LED digital display, which allows users to monitor and adjust the stirrer's speed with great accuracy. The stepless speed adjustment feature enables fine-tuning of mixing conditions, tailored to the specific requirements of each application. The stirrer also features mechanical speed control, ensuring stable and reliable operation even in demanding work environments.

The ergonomic and compact design of the RW 20 is crafted to maximize user comfort while minimizing bench space usage. With its reduced dimensions of 88 x 294 x 212 mm and lightweight of 3.1 kg, the stirrer is easy to handle and integrate into various laboratory setups. Its robust construction is designed to withstand continuous and intense operational conditions, providing exceptional durability.

The stirrer also includes advanced safety features, such as an integrated safety circuit that protects both the user and the device from potential hazards. The hollow shaft system with push-through capability simplifies the rapid and easy change of stirring tools when stationary, enhancing operational efficiency.

With a maximum torque range of 150 Ncm at lower speeds and the ability to handle materials up to 10,000 mPas in viscosity, the RW 20 is perfectly suited for complex mixing tasks. Its chuck range of 0.5 to 10 mm offers compatibility with a variety of stirring tools, providing maximum flexibility for mixing applications.

The RW 20 is also compatible with the labworldsoft® laboratory software, allowing for advanced integration and automated control, thus optimizing mixing processes and improving overall laboratory efficiency.

The IKA RW 20 is a high-performance overhead stirrer that combines power, precision, and safety in an ergonomic design. Whether working with large volumes, viscous materials, or requiring exceptional precision, the RW 20 is designed to meet the stringent demands of modern and demanding laboratory environments.
