Corning's enhanced T-75 Flask features a U-shaped design, which improves usability while maintaining the same environment for cell growth as previous designs. The U-shaped T-75 flask includes design advances, such as rounded shoulders, which allow for an easier grip and for better access when removing or tightening the cap. The new ergonomic shape also reduces the number of corners, improves cell scraping, and provides the option to use a larger pipet (up to 50mL).
