Product Literature

With a 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 chamber sizes. PLUS models include 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%.

The ST-45 and ST-45 Plus models come with 2 shelves. The ST-180 and ST-180 Plus models come with 3 shelves.
