Incu-Shaker™ CO2 Shaking Incubator is designed to maintain a stable environment for your cell cultures and to minimize contamination. It's unique and proprietary heat distribution technology provides the highest levels of temperature accuracy with minimal fluctuation (within 0.1°C). The six-side heating system, in combination with a low speed internal fan, uniformly spreads air throughout the chamber (without air exchange from the external environment). The chamber walls are constructed of high grade (316) stainless-steel, and all corners are rounded, preventing the accumulation of dirt/debris. For added security, it features an internal alarm to alert the user if the CO2 percentage changes, or the temperature fluctuates by more than 1°C from the set point. In addition, a “quick-cal” calibration button allows for quickly adjusting the chamber temperature to match that of a properly calibrated external thermometer.
