DWK Life Sciences: Silicone Lids
The speed and the associated oxygen intake only in-crease in a limited manner. The new 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 oxy-gen intake can be increased.
Laboratory tests showed that the oxygen intake could be doubled due to the chicanes in contrast with the standard Erlenmeyer flasks.
Due to completely automated machine manufacturing, the Erlenmeyer flasks with baffles are geometrically repro-ducible. The wall thickness of the flasks has been in-creased 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 en-ables reproducible gas exchange in contrast with other closure options, such as sealing with cotton wadding or similar.
