Bellco 7728 Roll-In Incubator Overview
The Bellco 7728 was developed around a very different workflow from a conventional general-purpose laboratory incubator. Instead of simply providing shelves for flasks, plates, and culture dishes, its large roll-in chamber is designed to accommodate Bellco Cell Production Roller Apparatus and other substantial equipment used for higher-volume cell culture.
The standard 7728 platform provides approximately 40 cu. ft. of internal capacity, with a tall chamber measuring roughly 35"W × 26"D × 76"H. The flush-to-floor design eliminates a substantial threshold at the chamber entrance, allowing compatible roller apparatus to be moved directly into and out of the incubation environment.
This can be a significant advantage for laboratories using large roller bottle systems. Rather than transferring individual bottles between an incubator and separate roller equipment, compatible roller apparatus can operate directly inside the controlled-temperature chamber.
Internal convenience outlets provide electrical power for equipment installed inside the incubator. In addition to roller apparatus, this can support compatible roller drums, magnetic stirrers, rockers, and other laboratory equipment when appropriate for the application.
For laboratories that do not require the entire chamber for roller equipment, shelf tracks allow optional stainless steel shelving to be installed. This gives the Bellco 7728 flexibility to support more conventional culture vessels and laboratory samples as well as specialized cell production equipment.
Common Applications
The Bellco 7728 is particularly well suited for biotechnology, pharmaceutical research, vaccine development, cell biology, virology, bioprocess development, adherent cell culture, and other applications involving roller bottle systems or large quantities of cultured cells.
Roller bottle culture has historically been used when laboratories need greater adherent cell growth surface than conventional stationary flasks can provide. Slowly rotating bottles continually expose cultured cells to growth medium while allowing gas exchange, making roller systems useful for producing larger quantities of cells, viruses, vaccines, recombinant products, and other biological materials.
The Bellco 7728 provides the temperature-controlled environment required around that equipment while allowing the roller apparatus to operate continuously inside the chamber.
Its large capacity also makes the 7728 useful beyond dedicated roller bottle applications. Depending on the chamber configuration and installed accessories, laboratories can use the space for large sample loads, multiple culture vessels, specialized incubation equipment, or other experiments requiring considerably more room than a conventional benchtop incubator can provide.
Laboratories performing cell culture and bioprocessing may use the Bellco 7728 alongside biosafety cabinets for aseptic sample handling and laboratory centrifuges for harvesting and processing cells. Laboratory refrigerators provide storage for media and reagents, while ultra-low temperature freezers support longer-term preservation of cell stocks and other biological materials.
Cell Types & Culture Recommendations
The Bellco 7728 is particularly useful for laboratories working with adherent cell cultures grown in roller bottles. Its large interior provides the space necessary to operate multi-position roller apparatus inside a controlled-temperature environment.

Other equipment compatible with the chamber and internal electrical capacity
The ability to place powered equipment directly inside the incubator is one of the most important advantages of the 7728 design. Large roller systems can remain in continuous operation under controlled-temperature conditions rather than requiring separate incubation and rotation processes.
The chamber can also be configured with optional shelving when conventional vessels need to be incubated. Laboratories should consider both the dimensions of the equipment and the need for adequate airflow when planning the interior configuration.
Temperature Control & Environmental Stability
The standard Bellco 7728 uses forced-air circulation and microprocessor temperature control to maintain stable conditions throughout its unusually large chamber.
Fans draw chamber air through the heating system and redistribute conditioned air through the interior. Active circulation is especially important in a 40 cu. ft. incubator because samples or roller bottles may be positioned across a much larger vertical area than in a conventional benchtop unit.
For standard non-refrigerated 7728 configurations, the operating temperature range is approximately 9°C above ambient to 50°C. Temperature uniformity is approximately ±1.5°C at 37°C under specified conditions with a fully loaded roller apparatus.
A microprocessor-based temperature controller allows users to set and monitor chamber temperature digitally. An independent safety thermostat provides additional over-temperature protection if the primary control system fails.
The chamber's large viewing window allows researchers to observe roller apparatus and other equipment without opening the door. This is especially useful during long-duration cell culture procedures because unnecessary door openings can disrupt chamber temperature and expose cultures to changes in the surrounding laboratory environment.
Internal electrical outlets provide power for compatible equipment operating inside the chamber. This integration is fundamental to the 7728 platform: the incubator serves not simply as a heated storage cabinet, but as a controlled-temperature environment in which active cell production equipment can operate continuously.
For laboratories performing large-scale roller bottle culture, the combination of 40 cu. ft. capacity, forced-air temperature control, internal electrical power, and flush-to-floor loading makes the Bellco 7728 fundamentally different from a conventional general-purpose incubator.

Electrical Requirements
Confirm individual unit configuration
Bellco manufactured multiple 7728 configurations, including standard, refrigerated, and CO₂ versions. Specifications above describe the standard roll-in platform where applicable. Confirm the exact configuration, electrical requirements, chamber dimensions, temperature range, outlets, shelving, and included accessories for the individual incubator before purchase.
A roll-in incubator is a large floor-standing chamber designed so compatible laboratory equipment can be moved directly into the temperature-controlled environment. The Bellco 7728 uses a flush-to-floor entrance specifically to make loading large Cell Production Roller Apparatus easier.
