This Corning high yield performance flask manual (HYPERFlask M) cell culture vessel is specifically designed for manual use. Originally, the HYPERFlask cell culture vessel was developed for automation. Due to its popularity for use on the bench top, Corning has redesigned the HYPERFlask M vessel with new features. It has an innovative 10 layer design of interconnected gas permeable polystyrene growth surfaces, and is Corning CellBIND Surface treated for superior cell attachment and growth, allowing a ten-fold higher cell yield that increases productivity and capacity. It has a new ergonomic cap with a smooth texture on the liner that allows more ergonomic closing and opening. The new adaptor grid allows for faster filling and emptying while reducing foam generation. Reduce processing time and incubator storage space by handling one flask compared to 10 traditional 175sq cm flasks. Each individual flask is traceable by a serial number that can be read by the unaided eye or by a handheld bar code reader. It is made with USP Class VI materials molded and assembled in a Certified Class 100,000 clean room.
