Thermo Scientific HERAcell VIOS 160i CO₂ Incubator

Overview

The Thermo Scientific HERAcell VIOS 160i CO₂ Incubator is an advanced, high-capacity cell culture environment system engineered for reproducible, physiologically relevant mammalian cell growth under tightly controlled atmospheric conditions. It operates on a dual-gas (CO₂/O₂) regulation platform with integrated humidity management and active airflow dynamics—enabling stable setpoint maintenance even during frequent door openings. At its core, the incubator employs THRIVE™ Active Airflow Technology, which ensures rapid, uniform redistribution of temperature, CO₂, O₂, and humidity across the entire 165 L chamber volume. This architecture eliminates thermal stratification and gas boundary layers common in conventional forced-convection incubators. The system’s real-time environmental fidelity is maintained through in-chamber, in-situ sensing—placing all critical sensors directly within the culture space rather than in recirculation ducts or external chambers. This design minimizes lag time and improves responsiveness to perturbations, supporting applications ranging from primary cell expansion to stem cell differentiation and organoid development.

Key Features

• THRIVE™ Active Airflow System: Delivers consistent laminar air exchange across the full chamber volume, achieving full recovery of temperature, CO₂, O₂, and humidity within ≤10 minutes after a standard door opening event.
• Dual-Temperature PID Control: Two independent platinum resistance thermometers (Pt100) with proportional-integral-derivative logic prevent overshoot during thermal recovery, ensuring strict adherence to ±0.3 °C uniformity across the working volume.
• MEMS-Based IR180Si CO₂ Sensor: Utilizes silicon-microelectromechanical systems (MEMS) infrared emitter technology—replacing traditional incandescent sources—to deliver long-term stability, immunity to humidity/temperature drift, and extended service life (>10 years typical).
• TC180 Thermal Conductivity CO₂ Sensor Option: A robust, lamp-free alternative offering high repeatability for routine CO₂ monitoring without calibration drift due to ambient pressure or humidity fluctuations.
• O₂ Control Flexibility: Configurable hypoxic (1–21% O₂) or hyperoxic (5–90% O₂) operation enables physiological modeling of tissue-specific microenvironments—including neural, pulmonary, retinal, and embryonic niches.
• Steri-Run™ 180 °C Dry-Heat Sterilization: Fully automated, single-button cycle achieves ≥6-log reduction of bacteria, fungi, spores, and mycoplasma across all interior surfaces—validated per ISO 14644-1 Class 5 (ISO-5) cleanroom air quality standards post-cycle.
• 100% Electrolytic Copper Interior: Provides inherent antimicrobial properties, corrosion resistance, and ease of cleaning without chemical passivation—supporting long-term sterility assurance and regulatory compliance in GxP workflows.

Sample Compatibility & Compliance

The HERAcell VIOS 160i accommodates standard SBS-format multiwell plates (6–384-well), T-flasks (up to T225), roller bottles, Petri dishes, and custom bioreactor vessels. Its chamber geometry and shelf configuration support both static and dynamic culture formats. All materials in contact with the internal environment—including gaskets, shelves, and humidification pans—are USP Class VI certified and non-cytotoxic per ISO 10993-5. The incubator meets IEC 61010-1 safety requirements and is designed to operate within GLP, GMP, and ISO 13485 quality management frameworks. Optional Thermo Fisher Connect™ software enables electronic recordkeeping compliant with FDA 21 CFR Part 11, including user authentication, audit trail generation, and secure data export for regulatory submissions.

Software & Data Management

The iCAN™ touchscreen interface—mounted ergonomically on the front door—provides intuitive, context-sensitive navigation with multilingual support (English, German, French, Spanish, Chinese, Japanese). Real-time parameter visualization includes trend graphs for temperature, CO₂, O₂, and relative humidity over customizable time windows (1 hr to 30 days). All operational events—including door openings, alarm triggers, sterilization cycles, and sensor calibrations—are timestamped and stored locally with >1 year of continuous logging capacity. Data export is supported via USB drive or network interface (Ethernet) in CSV or PDF format. When integrated with Thermo Fisher Connect™ cloud services, remote monitoring, role-based access control, and centralized fleet management become available—facilitating multi-site lab coordination and CAPA documentation.

Applications

• Stem cell maintenance and directed differentiation under defined hypoxic conditions (e.g., 5% O₂ for mesenchymal stem cells)
• Primary neuronal culture requiring precise O₂ modulation to mimic brain parenchyma oxygenation
• Tumor spheroid and organoid development where metabolic gradients influence morphology and drug response
• Monoclonal antibody production using CHO or HEK293 cell lines demanding tight CO₂ and humidity control
• Regenerative medicine workflows involving co-cultures sensitive to transient pH shifts from CO₂ fluctuations
• Biobanking operations requiring validated, repeatable environmental recovery profiles for cryopreserved cell line retrieval

FAQ

What is the difference between the IR180Si and TC180 CO₂ sensors?
The IR180Si uses MEMS-based infrared detection for high accuracy and long-term stability, especially in variable-humidity environments. The TC180 relies on thermal conductivity principles and offers excellent cost-performance balance for routine CO₂ monitoring without sensitivity to background gas composition.
Does the incubator support validation documentation packages?
Yes—Thermo Fisher provides IQ/OQ documentation templates aligned with ASTM E2500 and ISO 14644 standards. Factory-installed options include temperature mapping reports and sensor calibration certificates traceable to NIST.
Can the Steri-Run™ cycle be scheduled remotely?
When connected to Thermo Fisher Connect™, users may initiate, monitor, and receive notifications for Steri-Run™ cycles from any authorized device via web browser or mobile application.
Is copper interior compatible with ethanol-based disinfectants?
Yes—the 100% electrolytic copper surface is chemically inert to 70% ethanol, isopropanol, and hydrogen peroxide vapor, enabling routine decontamination without surface degradation.
How often does the HEPA filter require replacement?
Under normal laboratory use (≤4 door openings/day), the integrated HEPA filter maintains ISO-5 air quality for ≥12 months; filter status is monitored automatically and displayed on the iCAN™ interface.
