  • Achieve your next breakthrough.
  • The Thermo Scientific Heracell VIOS 250i CO2 Incubator 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.
  • Better solutions for optimal cell growth. Our CO2 incubators with non-corrosive stainless-steel interior chambers provide the ideal in-vitro environment.
  • Large 255L capacity provides space for high throughput applications and accommodates spaces for culture devices for larger sample output.

Direct heat chamber:

  • 255 L (9.0 cu.ft.) electropolished stainless steel 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.

Wireless Monitoring Solution:

  • Thermo Scientific DeviceLink HUB, our easy-to-install solution, works with the Thermo Fisher Cloud to monitor conditions inside your CO2 incubators.
  • DeviceLink HUB monitors chamber temperature, gas levels, alarms, and alerts from the incubator data output connection, RS-232 or USB.
  • Alarms and notifications are also sent to the user by email and mobile push notification.
  • DeviceLink HUB is an optional accessory for models with the iCAN touchscreen interface.
  • DeviceLink HUB is available in the following regions:
  • United States and Canada.
  • 28 members of the European Union.
  • Iceland, Liechtenstein, Norway, and Switzerland.

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.
