The modular design of the CELLROLL allows the user to easily scale-up production depending on the needs: one motor unit can control between one and eight bottle racks, each rack accommodating two standard roller bottles. The moisture-resistant motor unit is available with rotation speeds of either 1-2 rpm or 2-6 rpm and is steered by a programmable control unit located outside of the incubator. In case of power failure or accidental disconnection of control and motor unit an alarm system is activated. The corrosion-free and sturdy construction makes the CELLROLL a reliable cell culture system that will keep your cells always on the move. Features and benefits: - Strong motor unit for rolling up to 16 roller bottles for easy and economic scale-up - 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. - Several user-selectable rolling options for maximising the growth of specific cell lines.
