Caron 7401-33-1 Overview
The Caron 7401-33-1 was designed for laboratories that need to maintain a large, tightly controlled CO₂ environment around orbital shakers, high-volume cultures, or other powered laboratory equipment.
A typical benchtop CO₂ incubator provides approximately 5 to 7 cu. ft. of usable chamber capacity. The Caron 7401-33-1 expands that capacity to approximately 33 cu. ft. (934 L) within a single floor-standing reach-in chamber.
This large volume can reduce the need to divide production among multiple smaller incubators and provides substantially more flexibility for scale-up applications.
The 7401 platform is also specifically shaker ready. Three reinforced stainless steel shelves are designed to support compatible orbital shakers and other substantial laboratory equipment, with each shelf rated for up to approximately 150 lb.
Three GFCI-protected electrical outlets are located inside the chamber, allowing powered equipment to operate within the controlled environment without routing power cords through the chamber door.
Because operating shakers and other equipment generate heat, Caron incorporates active refrigeration into the 7401 platform. The refrigeration system removes excess thermal load and helps the chamber maintain the selected temperature even while powered equipment is operating inside.
This particular 7401-33-1 adds two especially valuable capabilities: active humidity control and Caron's STER301 H₂O₂ sterilization module.
Together, these systems allow the chamber to precisely regulate temperature, CO₂, and relative humidity while also providing an integrated method for chamber decontamination between culture campaigns.
Common Applications
The Caron 7401-33-1 is particularly well suited for production-scale cell culture, suspension cell culture, vaccine research and production, antibody development, biotechnology, pharmaceutical research, personalized medicine, cell therapy research, bioprocess development, recombinant protein expression, and other high-volume culture applications.
One of its strongest applications is supporting orbital shakers used for suspension cultures. Rather than relying on multiple smaller incubated shakers, laboratories can place compatible shaker platforms within the much larger Caron chamber and maintain controlled temperature, CO₂, and humidity around the entire system.
This can be particularly useful when scaling cultures into larger shake flasks or when several shaker platforms must operate under the same environmental conditions.
Active humidity control provides an additional advantage for long-duration cultures and evaporation-sensitive applications. Researchers can regulate relative humidity to a defined setpoint rather than relying solely on passive water-pan humidification.
The integrated STER301 system also makes the unit attractive for workflows in which contamination control and repeatable chamber decontamination are important between culture campaigns.
Cell culture laboratories may pair the Caron 7401-33-1 with biosafety cabinets for aseptic culture manipulation and laboratory centrifuges for harvesting, washing, and downstream cell processing. Laboratory refrigerators provide storage for media and reagents, while ultra-low temperature freezers support long-term storage of cell banks and biological samples.
Cell Types & Culture Applications
The Caron 7401-33-1 can support a broad range of CO₂-dependent cell culture applications, but its large chamber, shaker-ready construction, active humidity control, and integrated sterilization capability make it especially well suited for higher-volume and production-oriented workflows.

The chamber provides approximately 32"W × 27"D × 65.7"H of interior space. Three reinforced shelves measure approximately 29.25"W × 24.45"D and support up to 150 lb. each.
When operating shakers within the chamber, users should confirm equipment dimensions, platform excursion, weight, electrical requirements, heat generation, and clearance requirements before installation.
Temperature, CO₂ & Controlled Humidity Performance
The Caron 7401-33-1 combines heating, active refrigeration, controlled humidification, infrared CO₂ sensing, and microprocessor monitoring to establish stable conditions throughout its large reach-in chamber.
The unit provides a published temperature range of approximately 20°C to 60°C under specified operating and internal heat-load conditions, with temperature control of approximately ±0.1°C and uniformity of approximately ±0.3°C.
An RTD sensor provides temperature feedback to the chamber control system.
Active refrigeration is particularly important when orbital shakers are operating inside the incubator. Motors and electronics continuously release heat, potentially pushing a conventional heated chamber above its desired setpoint.
The Caron 7401-33-1 can actively remove that heat, helping maintain stable culture conditions even when powered equipment is running inside the chamber.
CO₂ concentration is adjustable from 0% to 20% and is monitored by an infrared CO₂ sensor. IR sensing is well suited to high-humidity culture environments because CO₂ measurement is not dependent on the thermal conductivity of the chamber atmosphere.
This specific unit also includes active controlled humidity.
Relative humidity can be regulated from ambient conditions to approximately 95% RH, with control of approximately ±3% RH under specified conditions. This allows humidity to function as a defined chamber parameter alongside temperature and CO₂.
For extended cell culture workflows, high and stable humidity can reduce evaporation from culture media. Adjustable humidity can also improve repeatability when environmental conditions themselves are part of the experimental or production process.
STER301 H₂O₂ Sterilization System
A major advantage of this particular Caron 7401-33-1 is the inclusion of the Caron STER301 H₂O₂ Sterilization Module.
The STER301 system is designed to use hydrogen peroxide as part of a controlled chamber sterilization process, providing an integrated decontamination method for the incubator interior. This is especially useful in large reach-in chambers where manually wiping every internal surface, shelf support, plenum component, and other chamber feature can be substantially more labor-intensive than cleaning a small benchtop incubator.
The system uses a dedicated sterilization module and hydrogen peroxide consumables to distribute H₂O₂ throughout the chamber. Caron's STER301 maintenance system includes components associated with the sterilization process, including an ultrasonic nebulizer wick, catalyst components, and a hydrogen peroxide canister.
For laboratories operating multiple cell culture campaigns, the sterilization system provides a useful additional layer of contamination control between experiments, cell lines, or production runs.
The STER301 system should be viewed as part of a broader contamination-control strategy rather than a replacement for routine laboratory practices. Shakers, flask clamps, electrical cords, removable accessories, spills, and culture residues should still be addressed according to the laboratory's established cleaning and decontamination procedures.
Contamination Control & Chamber Design
The 7401-33-1 uses a Type 304 stainless steel chamber interior, providing a durable surface suited to the warm, humid environment associated with cell culture.
Removable interior components help provide access to chamber surfaces during routine cleaning. Glass inner doors allow users to inspect cultures and operating equipment while minimizing unnecessary disruption of the overall chamber environment.
Contamination control is particularly important in a large shaker-ready incubator because equipment operated inside the chamber introduces additional surfaces, moving parts, cables, flask clamps, and other potential contamination sites.
This configuration addresses that challenge through a combination of cleanable stainless steel construction and the STER301 H₂O₂ sterilization system.
For laboratories culturing multiple cell lines or working with valuable production cultures, the ability to perform a dedicated chamber sterilization cycle between campaigns can provide an important additional safeguard against cross-contamination and persistent chamber contamination.

Caron 7401-33-1 with STER301 Frequently Asked Questions
What makes this Caron 7401-33-1 different from a conventional CO₂ incubator?
This configuration combines 33 cu. ft. of chamber capacity, shaker-ready shelving, internal electrical power, refrigeration, infrared CO₂ sensing, active humidity control, and STER301 H₂O₂ sterilization. It is designed for substantially larger and more demanding cell culture workflows than a typical benchtop CO₂ incubator.
What is the Caron STER301?
The STER301 is Caron's H₂O₂ Sterilization Module. It is designed to provide an integrated hydrogen peroxide-based sterilization process for compatible Caron chambers, adding an automated chamber decontamination capability to the incubator.
Why is H₂O₂ sterilization useful in a large reach-in CO₂ incubator?
A 33 cu. ft. chamber has far more internal surface area than a conventional benchtop incubator. Shaker-ready applications also introduce equipment, shelves, platforms, cables, and other surfaces into the culture environment. An integrated H₂O₂ sterilization system can help decontaminate difficult-to-access chamber surfaces between culture campaigns and supplement routine manual cleaning.
Does the STER301 eliminate the need to clean the incubator?
No. H₂O₂ sterilization should be used as part of a broader contamination-control program. Spills, residues, culture media, removable equipment, shaker components, and other contamination sources should still be physically cleaned and maintained according to appropriate laboratory procedures.
