We were able to show that the Duran baffled flask exceeds the classical Duran Erlenmeyer flask in oxygentransfer capacity by more than 50%, enabling a better aeration for aerobic cultures. Figure 1.

Transfer the reaction mixture to an Erlenmeyer flask and wash the Duran bottle twice with ∼ 20 ml of Et 2 O. Swirl the bottle several times so that any product remaining between the tubings is ...

Under these conditions a k L a value of 160 h-1 ± 7% for the Duran baffled flask and a k L a value of 100 h-1 ± 3% for the Erlenmeyer flask were determined (Figure 1).We were able to show that ...
