Laboratory Tutorials | Laboratory glassware reprocessing – avoiding glass corrosion (Dr. Weigert tutorial)

If you work in a laboratory on a daily basis, you will know that there is more to cleaning than meets the eye. Clean and, especially, residue-free laboratory glassware is essential to safe and successful work in the lab. The many different types of contamination in a laboratory environment mean that residue-free and value-preserving cleaning is particularly challenging and raises specific questions. The Dr. Weigert tutorial series “Laboratory glassware reprocessing” provides tips and recommendations for daily laboratory practice relating to cleaning and hygiene. This tutorial is about how glass corrosion can be prevented. Glass corrosion, i.e. structural change of the glass surface, arises as a result of the wrong choice of cleaning process, for instance. In addition to loss of accuracy of volumetric instruments such as pipettes, laboratory glassware or measuring cylinders, glass corrosion leads to colour removal of scales. This reduces the service life of the laboratory glassware and can even cause distorted analysis results. In this tutorial, Dr. Weigert shows that automated reprocessing is a gentle type of cleaning. By selecting the right cleaning agent that is specifically geared towards the task in hand and preserves materials, the materials used can last even longer, and glass corrosion can be prevented.
