R 1385, Propeller stirrer, 3-bladed, Ø140 mm, 550 mm

R 1385 propeller stirrer with three blades enables efficient mixing in laboratory stirring applications. The impeller diameter measures 140 mm while the shaft length reaches 550 mm with a shaft diameter of 10 mm. Its streamlined geometry draws material upward from the vessel bottom, generating low shear forces during operation. The three-bladed configuration performs reliably at medium to high speeds across a range of viscosities. This accessory supports controlled agitation processes that require consistent flow patterns without excessive mechanical stress on sensitive samples. The design integrates effectively into standard laboratory mixing setups where reproducible results depend on stable impeller performance. Users obtain uniform distribution of components while preserving sample integrity throughout extended stirring cycles. The product contributes to precise experimental conditions in chemical and biological research environments from manufacturer IKA. Its robust stainless-steel build ensures long-term durability and easy cleaning between experiments involving aqueous or organic media. Researchers commonly employ the stirrer when preparing homogeneous reaction mixtures or maintaining suspension of solids in analytical protocols.
