DURAN Baffled Flask, GL 45, without membrane screw cap and pouring ring, 250 mL

Description

Manufactured from borosilicate glass 3.3 | 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 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, with and without membrane screw cap and pouring ring | 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
