CellTumbler presentation
CellTumbler is an affordable rocking device supporting the well-known cell culture wave-bags from various suppliers ranging from 0.5/1 litre up to 10/20 litre bag size. CellTumbler is not limited to a specific supplier of bags. In general, the CellTumbler is a stand-alone instrument with reduced complexity and very easy to use.

CellTumbler is available in 4 sizes – look at this link . We describe the wave-bag with "liquid volume" and "total volume" - which is 50% liquid and 50% gas. A bag with total fluid (gas and liquid) volume is like 10 liter containing 5 liter liquid. The 10/20 bag for 10 liter liquid and 10 liter gas.
Reducing gradients and improve aeration at the same time is not easy in a wave-bag with laminar flow. We developed the simple, but efficient half-pyramid ad-on device to CellTumbler. A variety of CellTumbler half-pyramids shown on a CellTumbler tray.
The short video above show how the CellTumbler with traditional wave-bags create the laminar wave motion inside the rectangular plastic foil bag.
The video above show non laminar mixing. Adding the two half-pyramid as shown above changes completely the motion into a large 8 of liquid flow. Much better aeration and reduced gradients. All translates into better mass transfer.
