In general, when using Lonza's CytoSMART™ Device, the flask needs to be below 4.5 cm in height. Most culture flasks (including T-25, T-75, and T-150 flasks) will be acceptable. For larger flasks, such as T-162 flasks, Corning/Costar T-162 Flasks are 4 cm (1.6 inches) in height and fit on the Lonza CytoSMART™ Device.
