Testing

Most of our equipment is used and reconditioned. Our technicians test incubators using a calibrated digital chart recorder to verify the accuracy of temperature controls and readouts. We replace any hardware or parts as is necessary and clean all incubators thoroughly prior to shipment.

Pictures

The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment.

We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.

Thermo Heracell VIOS 250i CO₂ Incubator – FAQs

What is the Thermo Heracell VIOS 250i CO₂ incubator used for?

The Thermo Heracell VIOS 250i is designed for precise environmental control in cell culture, tissue engineering, IVF, and pharmaceutical research applications. It maintains stable temperature, CO₂ concentration, and humidity, all of which are critical for sensitive biological samples.

What are the key features of the Heracell VIOS 250i?

Thermo VIOS 250i incubators are known for combining advanced contamination control with user-friendly operation, including:

255 L (9 cu. ft.) chamber capacity for high-throughput labs

ISO Class 5 HEPA filtration for continuous air purification

THRIVE active airflow system for uniform conditions and fast recovery

180°C Steri-Run sterilization cycle for complete decontamination

iCAN touchscreen interface with data logging and trend monitoring

Integrated humidity reservoir for stable >93% RH at 37°C

These features make it ideal for labs requiring reproducibility, sterility, and regulatory compliance.

How does the VIOS 250i prevent contamination?

While the high-heat sterilization cycle is the most obvious and well known contamination control feature on the VIOS models, these incubators actually use a multi-layer contamination control system.

This includes continuous HEPA filtration of chamber air every ~60 seconds combined with the high-temperature Steri-Run cycle (180°C) for full sterilization, supplemented by a covered humidity reservoir to reduce microbial growth and smooth stainless steel interior for easy cleaning. (Copper lined units may also be available for increase anti-microbial protection.) Together, these systems help maintain cleanroom-level conditions inside the chamber.

How does the Heracell VIOS 250i ensure uniform temperature and gas distribution?

The VIOS 250i uses a rear-wall air duct and optimized airflow pathway to evenly distribute heat and gases throughout the chamber. According to the operator manual, air is circulated from the fan along the rear wall and directed toward the chamber ceiling, ensuring consistent temperature and homogeneous CO₂ distribution across all shelves.

Additionally, the system actively mixes incoming gases with chamber air to maintain stable pH conditions in cell culture media, which depend heavily on CO₂ uniformity.

This design helps eliminate “hot spots” or uneven growth conditions, which is critical for uniformity and reproducible experimental results.

How effective is the Steri-Run high-temperature sterilization cycle?

The built-in Steri-Run sterilization program heats the chamber to 180°C, achieving a 12-log Sterility Assurance Level (SAL), a standard indicating near-total elimination of microorganisms.

Unlike manual cleaning alone, this automated cycle:

Sterilizes all interior surfaces without disassembly

Reduces reliance on chemical disinfectants

Ensures consistent, validated decontamination

For labs concerned with cross-contamination, this feature provides repeatable, audit-ready sterilization with minimal operator intervention.

Why choose the Thermo Heracell VIOS 250i over other CO₂ incubators?

The VIOS 250i stands out due to its combination of:

Advanced contamination control (HEPA + high-heat sterilization)

Fast recovery and uniform conditions

Intuitive digital controls

Proven reliability in demanding lab environments

It is a strong choice for labs that need consistent, contamination-free culture conditions at scale.
