Kuhner has designed a new F-size tray (800 x 420mm) which is ideal for cell culture. The F-V5000/7 tray allows parallel shaking of 7 x 3L Corning Fernbach culture flasks, 7 x 5L Corning Erlenmeyer flasks or 7 x 5L Thomson Optimum Growth flasks. Flasks are held in position by pins and are easily placed on the tray and removed just as quickly. The shaking speed is limited to a maximum of 150 rpm at 50 mm shaking diameter. This tray has been designed for easy cleaning and efficient handling of samples.
