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. Due to conical shape, the flasks is used for mixing liquids.

Marking Area

The marking area is a printed ceramic area on laboratory glassware for marking / identification using a wax pencil. Also called marking field, white marking spot or marking square.
