Thermo Forma Steri-Cycle 370 Direct Heat CO₂ Incubator
Maintaining sterile, stable environmental conditions is essential for successful cell culture, tissue engineering, and other sensitive biological applications. The Thermo Forma Steri-Cycle 370 Direct Heat CO₂ Incubator combines precise temperature and carbon dioxide control with an integrated high-temperature sterilization cycle, providing laboratories with a dependable platform for contamination-sensitive research. Featuring a 184-liter (6.5 cubic foot) chamber, direct heat technology, in-chamber HEPA filtration, and a fully automated 140°C sterilization cycle, the Steri-Cycle 370 has become a trusted solution for research laboratories seeking both environmental stability and simplified contamination control.
Unlike conventional direct heat incubators, the Steri-Cycle 370 continuously circulates HEPA-filtered chamber air to maintain ISO Class 5 (Class 100) air quality while rapidly removing airborne contaminants introduced during routine door openings. The direct heat design provides fast temperature recovery without the added weight and maintenance associated with water-jacketed systems, while the thermal conductivity CO₂ sensor maintains accurate atmospheric control from 0% to 20% CO₂. Combined with programmable microprocessor controls, high humidity, and an automatic sterilization cycle, the Steri-Cycle 370 is well suited for biotechnology, pharmaceutical, academic, clinical, and IVF laboratories requiring dependable long-term cell culture performance. Purchasing a refurbished Thermo Forma Steri-Cycle 370 from American Instrument Exchange provides laboratories with premium incubation technology at substantial savings compared with purchasing new equipment.
Thermo Forma Steri-Cycle 370 Direct Heat CO₂ Incubator Key Features
Approximately 184 L (6.5 cu. ft.) chamber capacity
The Thermo Forma Steri-Cycle 370 was developed for laboratories requiring highly stable environmental control together with advanced contamination prevention. Its 184-liter chamber accommodates tissue culture flasks, culture dishes, multiwell plates, spinner flasks, roller bottles, and other standard laboratory vessels while maintaining tightly controlled temperature, humidity, and carbon dioxide levels.
The incubator's direct heat architecture delivers rapid recovery following routine door openings, while the continuously operating HEPA filtration system quickly restores clean chamber air, minimizing the introduction of airborne particles that can compromise sensitive cell cultures. These features make the Steri-Cycle 370 particularly valuable for laboratories performing long-term cell culture experiments or maintaining valuable cell lines.

The Thermo Forma Steri-Cycle 370 Direct Heat CO₂ Incubator is commonly used for:
Mammalian cell culture
Primary cell culture
Stem cell research
Cancer biology
Tissue engineering
Regenerative medicine
Gene therapy research
Cell therapy development
Vaccine development
Pharmaceutical research
Biotechnology research
IVF and reproductive medicine
Academic biomedical research
Clinical laboratory research
Its combination of precise environmental control, continuous HEPA filtration, and high-temperature chamber sterilization makes it particularly well suited for contamination-sensitive biological research.
Ideal Laboratory Environments
The Steri-Cycle 370 is an excellent choice for biotechnology companies, pharmaceutical manufacturers, universities, hospital research centers, IVF laboratories, contract research organizations, and clinical laboratories requiring dependable incubation performance with enhanced contamination control.
Laboratories maintaining valuable cell lines, primary cultures, or long-duration experiments benefit from the incubator's integrated HEPA filtration and automated sterilization cycle, both of which help reduce contamination risk while minimizing routine maintenance.
Temperature Recovery and Environmental Stability
The Steri-Cycle 370 utilizes a direct heat heating system that provides rapid temperature recovery while maintaining excellent chamber uniformity. Temperature is adjustable from Ambient +5°C to 50°C, and the microprocessor controller continuously monitors both temperature and carbon dioxide levels to maintain stable incubation conditions throughout extended experiments. The thermal conductivity CO₂ sensor accurately regulates chamber atmosphere from 0% to 20% CO₂, supporting a broad range of standard mammalian cell culture applications.
The incubator also maintains relative humidity approaching 95% at 37°C, helping reduce evaporation of culture media during prolonged incubations. The tempered glass inner door allows cultures to be observed without exposing the entire chamber, reducing environmental disturbances and promoting rapid recovery following routine access.
HEPA Filtration and High-Temperature Sterilization
One of the defining characteristics of the Steri-Cycle 370 is its combination of continuous HEPA air filtration and an automated 140°C chamber sterilization cycle. The HEPA filtration system continuously circulates chamber air, restoring ISO Class 5 (Class 100) air quality within minutes after door openings, while the sterilization cycle decontaminates all internal chamber surfaces without requiring chamber disassembly or chemical disinfectants. The sterilization process typically completes in approximately 12 to 14 hours, simplifying routine maintenance and helping laboratories reduce contamination between research projects.
Sample Storage Recommendations
The 184-liter (6.5 cubic foot) chamber of the Thermo Forma Steri-Cycle 370 provides ample space for laboratories performing routine and advanced cell culture applications. The incubator accommodates tissue culture flasks, culture dishes, multiwell plates, roller bottles, spinner flasks, cell culture bags, and other commonly used laboratory vessels while maintaining stable temperature, humidity, and carbon dioxide conditions.
Adjustable stainless steel shelves allow users to configure the chamber for a variety of vessel sizes and research workflows. To promote optimal environmental uniformity, culture vessels should be distributed evenly throughout the chamber with sufficient clearance between shelves to allow unrestricted air circulation. Proper organization helps maintain consistent incubation conditions while supporting rapid environmental recovery after routine door openings.
The Steri-Cycle 370 is particularly well suited for laboratories maintaining multiple cell lines or long-term studies where contamination prevention and environmental consistency are essential. The continuous HEPA filtration system helps preserve clean chamber air throughout extended incubation periods while minimizing the introduction of airborne contaminants during routine access.
Energy Efficiency and Operating Costs
The Thermo Forma Steri-Cycle 370 was designed to provide dependable incubation performance while minimizing long-term operating costs. Its direct heat architecture eliminates the need for a water jacket, reducing instrument weight, simplifying installation, and allowing faster recovery following door openings. The direct heat system also requires less routine maintenance than traditional water-jacketed designs.
The integrated HEPA filtration system continuously maintains clean chamber air with minimal user intervention, while the automated 140°C sterilization cycle eliminates the need for chemical disinfectants during routine chamber decontamination. The polished stainless steel interior is easy to clean, and the microprocessor controller continuously monitors chamber conditions to maintain stable environmental performance throughout years of operation.
Combined with its durable construction and proven reliability, the Steri-Cycle 370 remains a cost-effective solution for laboratories requiring dependable contamination control and consistent cell culture performance.
