Plastic beaker crack#
It is definitely possible that there was already a small crack in the beaker and that heating caused it to open further.Ī contaminant is very unlikely to have been the source of the problem. Plastic beakers are a safer alternative to glass, won’t break, chip or shatter, are lightweight, chemical resistance, heat tolerant., polypropylene and polymethylpentene beakers provide precise measurements, reliable support and dispensing control, high quality laboratory grade plastic materials for dependably lower levels of potential leachables and extractables. An exception might be if the hotplate is malfunctioning and get extremely hot extremely quickly, but that doesn't seem likely. Choose from a variety of sizes of plastic lab beakers for chemistry science projects. However, if you heated the beaker steadily for 40 minutes, it definitely wasn't shocked into breaking. Usually lab glass breaks because of thermal shock - either hot glass with cold water or cold glass with hot water. You could try boiling another pair of similar beakers and check the time they take to boil to confirm.
