Benchmark ST-180 CO2 Incubator (180 L) 115V with three shelves

Benchmark ST-45 CO2 Incubator 45 Liter 115V with two shelves model # H3550-180 With our unique and proprietary heat distribution technology, the Benchmark ST Series of CO2 incubators provide 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 accumlation of dirt/debris. For added security, all models feature 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 chamer temperature to match that of a properly calibrated external thermometer. Two series (standard and PLUS) are each available in 45L and 180L chamb
