DURAN® baffled-bottom flask with GL 45 thread
Perhatian!
Spesifikasi DURAN® baffled-bottom flask with GL 45 thread
- Baffled-bottom flasks cause a turbulent flow, increase the gas exchange surface and produce a higher oxygen transfer
- Automated one-step production enables a reproducible geometry and comparable results
- Also available with membrane screw cap (gas exchange)
- Available in range of three sizes (250, 500 and 1000 ml) for process scale up
Comparison of the produced microbial mass (experiment with E.coli bacteria):
Movement of fluid on an orbital shaker:
When cultivating microorganisms in Erlenmeyer flasks on an orbital shaker, the oxygen intake is frequently the limiting factor for cell growth. The DURAN® Erlenmeyer flask with four bottom baffles interrupts the circular flow to create a turbulent flow. The gas exchange surface of the liquid is increased, so that the oxygen intake can be increased.
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 screw cap from the DURAN Group.
