IKA KMO 3 basic magnetic stirrer without heating, chemical-resistant glass surface, 0020004631

The IKA KMO 3 basic magnetic stirrer without heating (MPN 0020004631) is a highly optimised mechatronic, compact and laboratory-proven system solution for the continuous, gentle mixing and homogenisation of low- to medium-viscosity liquids. Designed for a stirring volume of up to 5 litres of water, this instrument combines a flat, space-saving industrial design with state-of-the-art control technology. In B2B laboratory environments within chemical analysis, biotechnology or pharmaceuticals, the reliable kinetics of a stirring system are the primary criterion for ensuring reproducible reaction conditions and error-free sample preparation in day-to-day routine operations.

Materials science excellence through a tempered glass surface

The physical foundation of the stirrer is its square base measuring 140 x 140 mm, which is made entirely from a specialised, tempered glass matrix. Compared to conventional plastic or uncoated metal surfaces, the glass plate offers uncompromising chemical inertness towards highly aggressive acids, alkalis and organic solvents. This choice of material not only guarantees exceptional scratch resistance and mechanical durability, but also enables rapid, residue-free cleaning and wipe disinfection, which reliably prevents cross-contamination between different test series.

Intelligent kinetics with programmable direction reversal

From a process engineering perspective, the KMO 3 basic impresses with a powerful, maintenance-free motor that covers a wide speed range from 10 to 1,500 revolutions per minute. A technological highlight is the integrated, automatic direction-of-rotation reversal (reverse function): The periodic change in the direction of rotation transiently disrupts the hydrodynamic flow profile within the vessel, which significantly accelerates mixing efficiency even with demanding or slightly inhomogeneous media. The brilliant, inverted digital display allows laboratory staff to keep a constant eye on the exact speed and timer settings.

Robust construction and future-proof connectivity

The long-term durability of the stirrer drive is ensured by a hermetically sealed housing with IP 42 protection. This structural barrier reliably protects the internal electronic circuit boards and the magnetic drive against the ingress of spilled media or dust-like particles. For seamless digital documentation and integration into automated laboratory networks, the device features integrated USB and RS232 interfaces. This enables all stirring parameters to be reliably transmitted to a higher-level laboratory management system and monitored via software.
