Erlenmeyer flasks, also known as Conical flask are a type of laboratory flask that is used to mix chemicals in. Due to their wide base with sides that taper upward to a short vertical neck, they are excellent to fulfil this purpose.
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.
