The CELLSPIN is a stirrer for cultivating cells in spinner bottles with culture volumes from 100 to 1000 ml. The speed (5-75 rpm) and other stirring parameters can be individually programmed and modified at any time via the control unit, which is located outside of the incubator. In case of power failure or accidental disconnection of control and spinner units an alarm system is activated. The corrosion-free and sturdy construction makes the CELLSPIN a reliable cell culture system that will keep your cells always on the move. Features and benefits: - Compact stirring unit suitable for four different flask sizes (100, 250, 500, 1000 ml) allowing convenient culture scale-up. - Optimised spinner flask design for improved medium oxygenation and minimal shear forces to create ideal cell growth conditions. - The control unit can be installed outside the incubator and the stirring unit is sealed in order to eliminate corrosion damage thereby guaranteeing reliable, long-lasting cell cultivation. - Easy system adaptation for the use of disposable or impeller-type spinner bottles for a wide range of culture systems and applications.
