The HeraCell VIOS 250i CO2 Incubator with Copper Interior is specifically designed to deliver the performance reliability, ease of operation, and value required to support a range of culturing needs from basic research to the demanding, leading-edge applications, so you're ready for whatever comes next.


Direct heat chamber

  • 255L (9.0 cu.ft.) 100% solid copper chamber with compact footprint, easily stackable
  • Standard left hand door swing, field reversible by qualified service support

THRIVE active airflow

  • In-chamber fan gently distributes clean, humidified air throughout the chamber ensuring homogeneous conditions
  • Fast recovery of all parameters in 10 minutes or less for stable culturing conditions
  • Auto-stop function disables fan operation during door openings to minimize air exchange

ISO Class 5 HEPA filtration

  • In-chamber HEPA continuously filters the entire chamber air volume every 60 seconds
  • ISO Class 5 clean room air quality is achieved in the culture chamber within 5 minutes
  • Continuous protection minimizes airborne contaminants settling on interior surfaces

Covered Integrated humidity reservoir

  • Directly heated water reservoir provides stable high relative humidity levels, preventing culture desiccation
  • Cover limits particles and spilled media from settling into the reservoir, keeping water clean
  • Separating water provides a condensation free incubation chamber, limiting areas for contaminants to breed
  • 5X faster humidity recovery than traditional water pan designs
  • Easy water handling: humidity reservoir may be filled or drained without removing shelves or cultures
  • Water level sensor indicates when a refill is needed

Steri-Run on-demand high temperature sterilization cycle

  • Independently validated overnight cycle ensures complete elimination of all biological contaminants
  • 180°C cycle designed for uniform 12-log sterilization on all chamber surfaces
  • Simplifies cleaning and eliminates the need for separate autoclaving and reassembly of components

Intuitive, interactive iCAN touchscreen control

  • Bright LED screen to monitor all incubator interactions
  • Provides visibility to changes in culture environment with performance trend graphing, error and usage logs
  • Convenient on-screen user prompts and reminders for easy navigation
  • Selectable languages simplify operation: English, Spanish, German, French, Italian, Japanese and Mandarin

In situ sensors and probes designed for precise control

  • Dual temperature probes for over temperature protection with operational back up
  • Thermal conductivity (TC) CO2 sensor with rH compensation designed for fast recovery and stable operation
