IKA R 401 Agitator shaft guard with hinge for overhead agitators, 0020122349

The IKA R 401 stirring shaft guard with hinge (MPN 0020122349) is an essential mechanical safety component for the safe and accident-free operation of overhead stirrers in the laboratory. During intensive mixing and homogenisation of viscous media, high kinetic forces act on the rotating stirring shafts. This professional shaft guard reliably protects laboratory staff from accidental contact with the rotating parts, effectively preventing clothing, hair or gloves from being drawn in. The guard is therefore a fundamental element in risk assessments and compliance with strict health and safety and accident prevention regulations (UVV).

Ergonomic access thanks to an integrated hinge mechanism

The design highlight of the R 401 model is its integrated, smooth-running hinge system. Unlike rigid protective covers, this hinged system architecture allows quick, unobstructed access to the drill chuck and the stirrer tool in use. Laboratory staff can carry out tool changes, adjustments to the immersion depth or cleaning tasks in a way that protects the material, without the need for time-consuming dismantling of the entire guard. This ensures a smooth workflow with high time efficiency in daily multi-user operation.

Material stability and unrestricted process visibility

The protective screen is made from a highly transparent, impact-resistant and specialised plastic material. This choice of material guarantees uncompromising chemical resistance to transient splashes of acids, alkalis or organic solvents. The material’s excellent optical clarity ensures that visual monitoring of the stirring process, transient flow patterns or any delays in boiling within the sample vessel remains completely unrestricted and error-free at all times.
