一般描述
When cultivating microorganisms in Erlenmeyer flasks on a vibrating board, the oxygen intake is frequently the limiting factor for cell growth.
In standard Erlenmeyer flasks, a liquid sickle forms, the size of which depends on the speed of the board and the vibration diameter. The larger the surface of the content, the larger is the gas exchange surface and with it the possible oxygen intake.
The speed and the associated oxygen intake only increase in a limited manner. The new Duran® Erlenmeyer flask with four baffles on the bottom interrupts the laminar flow to create a turbulent flow. The surface of the liquid and the gas exchange surface are increased, so that the oxygen intake can be increased.

- The membrane screw cap allows for gas exchange and can be reused
- Reduced cell growth due to limited oxygen transfer
