Beakers - PYREX - 400ml. Pyrex squat form beakers are high quality borosilicate 3.3 glass beakers, manufactured by pouring molten glass into moulds to provide walls and bases of uniform thickness throughout (cheaper beakers are often made from sections of glass tubing, with the base being separately attached). This leads to improved performance, with consistent expansion during heating, and reduces the likelihood of bases or walls cracking and breaking. Beakers come with white graduations and a pouring spout.
