Erlenmeyer flasks are a type of laboratory flask in which liquids may be stored. Due to their narrow necks, it is easy to mix the contents of the flask by swirling without the risk of spillage.
The flasks offered are made out of borosilicate glass. Borosilicate glass has excellent thermal properties both at high and low temperatures. Due to this, the glass may be heated without the danger of cracking. The maximum recommended temperature for borosilicate glassware is approximately 500 °C.
