Benchmark Scientific H3551-45P-E Benchmark ST-45 CO2 Incubator, 45 Liter, 230V with 2 Shelves, High Heat Decontamination, Humidity Control, Split Inner Door with 2 Compartments features unique and proprietary heat distribution technology, and 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, H3551-45P-E 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. H3551-45P-E includes advanced programming for high heat decontamination (at 125°C), a unique split inner glass door for access to the chamber without exposing it fully to the external environment and programmable humidity percentage, up to 95%.
