Erlenmeyer flasks are laboratory glassware in which liquids can be stored. Their narrow neck makes them very suitable for mixing liquids by swirling by reducing the risk of spillage.
The offered flasks are made of borosilicate glass. Borosilicate glass has excellent thermal properties at both high and low temperatures. This allows the glass to be heated without the danger of cracking. The maximum recommended temperature for borosilicate glassware is about 500°C.
