Spinner flasks have been used to grow cells in suspension for over 50 years. Now, Corning has re-engineered spinner flasks for maximum performance in a convenient, ready-to-use disposable design. The results are the innovative 1L and 3L Corning® disposable spinner flasks, the industry's newest, most advanced, productive and convenient suspension culture systems. The 3L spinner flasks will be available early 2008.
