IKA R 301 Plexiglas stirrer shaft guard, length adjustable 190–310 mm, 0002603000

The IKA R 301 stirrer shaft guard (MPN 0002603000) is an essential mechanical safety component for the safe and accident-free operation of laboratory overhead stirrers. During intensive mixing, dispersing or homogenisation processes, considerable kinetic forces act on rotating stirrer shafts. This professional shaft guard forms a physical barrier that reliably protects laboratory staff from accidental contact with the rotating parts. It effectively prevents clothing, hair or laboratory gloves from being drawn in, making the safety device a key component in risk assessments and ensuring compliance with strict national and international health and safety guidelines.

Stepless length adjustment for flexible experimental set-ups

From a process engineering perspective, the R 301 model excels thanks to its high degree of telescopic flexibility. The guard can be adjusted axially steplessly within a length range of 190 to 310 mm and locked into place precisely. This variable geometry allows for precise adaptation to different shaft lengths, vessel heights and varying immersion depths of the stirring elements. Laboratories thus benefit from a highly adaptable protective system that can be flexibly integrated into changing experimental set-ups without compromising workplace ergonomics.

Unrestricted process control thanks to a high-quality Plexiglas matrix

The cylindrical protective screen is made entirely from a high-purity, mechanically stable Plexiglas matrix. This material combines minimal weight with outstanding optical clarity. Laboratory staff are able to monitor the mixture, transient flow patterns, phase transitions or any boiling delays in the sample vessel at all times, with absolutely no restrictions and without any risk of error. At the same time, the Plexiglas structure offers effective protection against transient media splashes and can be cleaned quickly and without leaving any residue.
