Beschreibung
Replacement safety screw 3 mm is a dedicated fastening spare for laboratory stopcock security systems. Designed with a 3 mm bore specification, the screw secures the spindle or plug in place and helps prevent unintended loosening during operation. It serves as a direct replacement part for the Witaflo red series from manufacturer Witeg, restoring the original locking function when the factory screw is lost or damaged. Supplied as a single piece with a net weight of 0,001 kg, the component is intended for routine maintenance of laboratory valves, taps and related flow-control fittings. Correct seating of the safety screw maintains alignment of the stopcock assembly and supports consistent sealing performance in daily laboratory use. Technicians can install the part quickly during servicing without exchanging the entire valve body. The defined 3 mm geometry matches the Witaflo red design, ensuring compatibility with existing apparatus used in analytical and preparative workflows. This small but essential spare keeps stopcock systems operational and secure under normal laboratory conditions.
This article is part of Grease, boiling stones & sealants, in Tools & accessories.

Questions about Spare overtwist safety device, ''Witaflo''
What is this article?
Spare overtwist safety device, ''Witaflo'' is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Grease, boiling stones & sealants, inside Tools & accessories, in Laborbedarf.
Grease seals a ground joint. Boiling stones give a liquid a place to start boiling so it does not bump. A sealant does the same job as grease when grease would contaminate the product. They are small, and they decide whether a joint weeps.
The small tools of the bench are what the hand actually holds: a spatula for a powder, forceps for an object that must stay clean, a brush for a narrow neck, a desiccator when a dried sample must not take up water again. None of these reads a measurement. They keep the measurement possible. The apparatus around them is listed under ISO laboratory apparatus.
