RoboFlask cell culture vessel saves space while increasing cell growth area. The versatile, 18 mm thick flask can be handled both automatically and manually because of its removable septum cap and provides growth area for cells of 92.6 cm2, yet takes up less than half the space of a T-75 flask. A 2-degree slope at the base of the flask aids in media and cell recovery. The flask, an efficient and secure testing tool compatible with a variety of robotics and lab systems, is available with either standard tissue culture treatment or with Corning CellBIND Surface treatment.
