R 1388, Propeller stirrer, 3-bladed, Ø140 mm, 800 mm

R 1388 propeller stirrer with three blades provides efficient mixing performance for laboratory vessels of varying sizes. The design incorporates an 800 mm shaft length, 10 mm shaft diameter and 140 mm stirrer diameter, generating upward flow with low shear forces. The stirrer from manufacturer IKA operates reliably at medium to high speeds while maintaining controlled circulation in chemical and biological preparations. Its flow-optimised geometry supports consistent agitation without excessive turbulence, making it suitable for research and development processes requiring reproducible mixing results. The three-bladed configuration integrates seamlessly with compatible overhead stirrers, enabling scalable laboratory workflows. Users in analytical and process laboratories appreciate the unit’s ability to accommodate standard vessel dimensions while delivering dependable performance across routine and specialised applications. Precision-machined components ensure minimal vibration and long service life even under continuous operation in demanding environments. Laboratory technicians routinely rely on this accessory during extended synthesis runs and sample preparation sequences where uniform distribution of reagents proves essential for achieving accurate analytical outcomes.
