Test tubes, beaded rim, borosilicate glass 4.9

LABSOLUTE® test tubes are made of special borosilicate glass 4.9 and have a beaded rim. Despite their thin walls they are relatively unaffected by major changes in temperature and local heating. They also have excellent chemical resistance especially against acids with the exception of hydrofluoric acid and hot concentrated phosphoric acid.
