FlexCap - one connection cap for all flask types

Wish you could measure real-time culture respiration in shake flasks? The new Kuhner FlexCap lets you connect all standard shake flasks to the Kuhner TOM online measurement system.

FlexCap - one connection cap for all flask types

The FlexCap is a universal silicone adapter lid that enables the utilization of various sizes of shake flasks in the Kuhner TOM system to measure the oxygen and carbon dioxide transfer rates. Its specific construction seals both the smaller and more narrow flasks (min. 25 mm inner diameter) and the larger and wider flasks (max. 55 mm outer diameter), respectively, using the same universal lid. With the FlexCap, cultivations in custom-made flasks and baffled shake flasks are now accessible for online measurements with the Kuhner TOM system.

In addition, the FlexCap can also be used for aeration of shake flasks with the FlowCon and GasDivider enabling users to run cell cultivations in a non-humidified and non-O2/CO2-controlled environment. The FlowCon provides a precise gas composition and flow rate, while the GasDivider humidifies and distributes the gas flow evenly to the inlet ports of the FlexCaps.

Besides the ports for air inlet and outlet, the FlexCap comes with an extra port for external feeding and sampling. Best of all, the FlexCap is reusable by autoclaving at temperatures up to 121°C without losing its mechanical performance.
