Description
Glass cutting knife with plastic handle is a practical laboratory tool for scoring and separating glass tubing in research, teaching and production environments. It features a replaceable blade made of Widia steel, giving a durable cutting edge suited to glass tubes, quartz tubing, threaded tubes and KPG tubing used in glassware preparation. The plastic handle offers a secure, comfortable grip for controlled scoring during repetitive work, while the interchangeable Widia steel blade can be swapped when the edge becomes worn, helping maintain cut quality without replacing the whole tool. Supplied as one piece with a net weight of 0,132 kg, this cutter from manufacturer Witeg supports everyday glassworking tasks such as shortening tubes, preparing joints and modifying apparatus components. Its straightforward design fits standard laboratory glass workshops and chemistry benches where clean, reliable cuts are required. Use it wherever consistent scoring of laboratory glass is part of routine setup and maintenance workflows.

Questions about Glass-cutting knife with plastic handle
What is this article?
Glass-cutting knife with plastic handle is the article on this page. Luminix Health distributes Witeg for laboratory use. It sits in Scissors, scalpels & dissecting instruments, inside Tools & accessories, in Labware.
Scissors, scalpels and dissecting instruments cut or hold tissue and tough samples. The edge and the shape, blunt or sharp, straight or curved, are the specification. A dissecting set is not a surgical implant set.
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.
