Corning this week introduced the HYPERFlask cell culture vessel for high-density cell culture. Although the vessel has the same dimensions as a standard T175 flask, it can grow approximately 10 times as many cells because of its multilayer design, the company said.
The HYPERFlask vessel has 10 equivalent layers, each containing a gas-permeable cell growth layer. These layers are joined together to form a multilayered culture vessel. The HYPERFlask incorporates an air gap between each layer for optimal gas exchange and each layer is treated with Corning CellBIND surface for optimum cell attachment and growth. HYPERFlask vessels are designed for manual use and for use with the Automation Partnership SelecT automated cell culture system.
