Duran baffled Erlenmeyer flasks

Duran baffled Erlenmeyer flasks are claimed to reduce cell growth, due to limited oxygen transfer, and cause a turbulent flow which increases the gas exchange surface.

With these flasks, users can produce a higher oxygen transfer. The baffled flasks come complete with a membrane screw cap.

Due to completely automated machine manufacturing, the Erlenmeyer flasks with baffles are geometrically reproducible. The wall thickness of the flasks has been increased to achieve high mechanical strength and longer 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 membrane cap from Duran. This enables reproducible gas exchange in contrast with other closure options, such as sealing with cotton wadding or similar. The cap can be re-used many times.
