Benchmark CO₂ Incubators

• Precision temperature control, 6-sided heating
• Precise monitoring over CO₂ with dual beam IR sensor
• Seamless, stainless-steel chamber
• Digital control of humidity percentage (PLUS models only)

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 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°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.

Two series (standard and PLUS) are each available in 45 L and 180 L 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%.
