The New Brunswick S41i is the only CO2 incubator with an Eppendorf shaker inside. The S41i precisely controls temperature, shaking speed, and CO2, providing the ideal environment for growing mammalian and stem cells in culture. Accepts flasks up to 4 liters. Standard perforated shelf allows for static incubation at the same time as shaking and a second static shelf can be added as an option. The world famous triple eccentric drive provides stable, uniform and vibration free motion – connected to the shaking platform by four encapsulated support rods. The drive mechanism located below the chamber ensuring that heat generated by the drive does not affect the critical environment within the chamber. The intuitive touch screen display and controls allows you to operate and monitor performance.
