RW 28 Digital: A High-Capacity Overhead Stirrer for Intensive Laboratory Use
The RW 28 digital from IKA is a high-performance overhead stirrer engineered for intensive mixing tasks in demanding professional environments. Specifically designed for stirring liquids of varying viscosities, it can handle up to 80 liters of water or fluids with viscosities up to 50,000 mPas, making it ideal for laboratories in chemistry, biology, pharmacy, and related industries.
This model features a finned-cooled condenser motor, paired with a friction drive and a two-speed gear mechanism, allowing for continuous speed adjustment from 60 to 1400 rpm (50 Hz). The user can precisely control stirring speed through an intuitive side-mounted rotary knob and a clear LED display, offering a ±1 rpm adjustment accuracy for optimal process control.
With a high maximum torque of up to 1144 Ncm at 60 rpm, the RW 28 digital delivers stable performance even during high-resistance mixing. The hollow shaft output allows for direct insertion of stirring elements, improving ergonomics and simplifying operations. An integrated motor protection system with a thermal sensor automatically shuts off the power in case of overheating, ensuring user safety and prolonging the device’s lifespan.
The stirrer is intended for indoor use only, mounted on a stable stand, and is compatible with a wide range of IKA accessories. For safe operation, the use of a stirring shaft guard is strongly recommended. The aluminium and thermoplastic housing ensures easy cleaning and maintenance.
Engineered for professional users, the RW 28 digital is particularly well-suited for university settings, research laboratories, and pharmaceutical institutions. With its robust construction, high torque, large stirring capacity, and continuous operation capability (100%), it is an essential tool for all demanding mixing protocols.
