Benchmark ST-45 CO2 Incubator, 45L, 115V with two shelves

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 degree 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 (304) stainless-steel, and all corners are rounded, preventing the accumulation 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 degree 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.

Note: For all International Orders, the buyer will be solely responsible for the customs clearance, duty, and taxes imposed on the package.
