Thanks to their exceptional properties, such as excellent chemical resistance, nearly inert behaviour and high usage temperature, the original DURAN® Erlenmeyer flasks are ideal for use in laboratories. Moreover, the uniform wall thickness, minimal thermal expansion and the resultant high thermal shock resistance are outstanding characteristics. Therefore, DURAN® Erlenmeyer flasks are particularly suited to use with very high temperatures and fast temperature changes.
