Thermo Scientific™ Heracell™ VIOS 250i CO₂ Incubator – Direct-Heat, 9 cu. ft. (255 L), TC CO₂ Sensor, 120 V

The Thermo Scientific™ Heracell™ VIOS 250i CO₂ Incubator is engineered to safeguard sensitive cell cultures through exceptional precision, uniformity, and contamination prevention. Its direct-heat system and water-reservoir humidity control maintain stable growth conditions, while advanced features reduce downtime and ensure optimal reproducibility.

A thermal-conductivity (TC) CO₂ sensor with relative-humidity compensation delivers fast, accurate gas-level measurement and quick recovery following door openings. The in-chamber HEPA filtration system continuously recirculates and cleans the air every 60 seconds, restoring ISO Class 5 clean-room conditions inside the chamber within five minutes.

To eliminate contaminants, the incubator offers a fully validated 180 °C high-temperature sterilization cycle achieving a 12-log reduction of biological organisms on all interior surfaces. Its electropolished stainless-steel chamber is corrosion-resistant, easy to clean, and designed for long-term reliability.

User interaction is simplified with a bright LED interface, on-screen prompts, and clear performance readouts. The Heracell VIOS 250i also includes a gentle in-chamber fan, auto-stop airflow during door openings, and a directly heated water reservoir to maintain consistent humidity and prevent culture desiccation.
