Due to completely automated machine manufacturing, the Erlenmeyer flasks with baffles from the DURAN Group are geometrically reproducible. The wall thickness of the flasks has been increased to achieve excellent mechanical strength and to guarantee a long product service life. The special manufacturing process means it is possible to manufacture the product complete with threading in a two-stage process. Hence the flasks can be sealed with the proven membrane screw cap from the DURAN Group. This enables reproducible gas exchange in contrast with other closure options, such as sealing with cotton wadding or similar. The cap can be reused many times.
