Due to the baffles incorporated in the product, a solution to be shaken breaks on it and oxygen is introduced into the solution.– Four baffled-bottom flasks cause a turbulent flow, increase the gas exchange surface and produce a higher oxygen transfer – At higher shaking speeds, the baffles increase aeration for better growth, especially with bacteria – The moulded bottom-baffles provide increased movement at lower speeds for a more gentle medium aeration of sensitive cultures – The flasks can therefore be sealed with the tried-and-tested membrane screw cap from the DWK Life Sciences which enables a reproducible gas exchange compared to other sealing mechanisms e.g. sealing with cotton wool – The flasks are manufactured in a fully automated process to provide totally consistent flask shapes leading to highly reproducible experimental conditions and results – The special production process enables the manufacture of the product complete with thread in a two-stage process – Available in range of three sizes for process scale up – The increased wall thickness of the flasks ensures excellent mechanical stability and a long service life. – Easy-to-read scale with graduation marks to estimate the content – Fired-on, highly durable white print Due to the baffles incorporated in the product, a solution to be shaken breaks on it and oxygen is introduced into the solution.– Four baffled-bottom flasks cause a turbulent flow, increase the gas exchange surface and produce a higher oxygen transfer – At higher shaking speeds, the baffles increase aeration for better growth, especially with bacteria – The moulded bottom-baffles provide increased movement at lower speeds for a more gentle medium aeration of sensitive cultures – The flasks can therefore be sealed with the tried-and-tested membrane screw cap from the DWK Life Sciences which enables a reproducible gas exchange compared to other sealing mechanisms e.g. sealing with cotton wool – The flasks are manufactured in a fully automated process to provide totally consistent flask shapes leading to highly reproducible experimental conditions and results – The special production process enables the manufacture of the product complete with thread in a two-stage process – Available in range of three sizes for process scale up – The increased wall thickness of the flasks ensures excellent mechanical stability and a long service life. – Easy-to-read scale with graduation marks to estimate the content – Fired-on, highly durable white print
