DURAN GROUP

In standard DURAN® 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 is increased, so that the oxygen intake can be increased. Laboratory tests showed that the oxygen intake could be doubled due to the chicanes in contrast with the standard DURAN® Erlenmeyer flasks.

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 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.

The DURAN® baffled flasks have a retrace code. If you enter that code along with the corresponding article number, you will be able to easily download a batch and quality certificate.
