Laboratory glassware reprocessing – removing labels (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 of laboratory glassware is particularly challenging. The Dr. Weigert tutorial series “Laboratory glassware reprocessing” provides tips and recommendations for daily laboratory practice on how to clean typical contaminants on laboratory glassware efficiently and with no residue. Label residue on laboratory glassware is one example of a familiar problem in laboratories. There are various label papers and label adhesives, some of which are easier to remove than others. For example, paper labels that can be individually inscribed are often used. Hazard warning labels can also be found on many items of laboratory glassware. And work at low temperatures, for example, requires the use of highly cold-resistant labels with outstanding adhesion properties (e.g. cryogenic labels for temperatures of minus 18 °C or below). This Dr. Weigert tutorial provides practical tips and recommendations for residue-free removal of labels.
