Test tubes, beaded rim, borosilicate glass 4.9

LABSOLUTE® test tubes made of borosilicate glass 4.9 have a beaded rim and a wall thickness of 0.5 - 0.6 mm. 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.
