SHEL LAB 1927 Overview

The SHEL LAB 1927 was designed around one principal advantage: large-scale CO₂ incubation within a single controlled chamber.

With approximately 40 cu. ft. of interior capacity, the 1927 is dramatically larger than a typical 5- to 7-cu.-ft. benchtop CO₂ incubator. This allows laboratories to consolidate large culture workloads into a single chamber and provides enough interior space for equipment and vessels that simply cannot fit inside conventional incubators.

The chamber measures approximately 35"W × 26"D × 76.5"H, providing a tall, open workspace that can be configured around different applications.

Six shelves are supplied with the standard platform and can be repositioned to accommodate different vessel heights. More importantly, the shelving can be removed entirely when the chamber is being used with compatible roller bottle equipment or other large apparatus.

The reinforced chamber floor was specifically designed with roller bottle applications in mind. Period manufacturer literature notes that the chamber was constructed to accommodate major manufacturers' roller apparatus, making the 1927 particularly attractive for laboratories performing high-volume adherent cell culture.

Five electrical outlets inside the chamber provide power for compatible equipment without requiring multiple cords to interfere with the door seal.

This combination of large chamber capacity, flexible shelving, internal electrical power, and a reinforced floor gives the 1927 capabilities that extend well beyond those of a conventional CO₂ incubator.

Common Applications

The SHEL LAB 1927 is particularly well suited for high-volume tissue culture, roller bottle culture, cell harvesting, biotechnology research, pharmaceutical development, vaccine research, antibody production, large-scale mammalian cell culture, and other applications requiring substantial CO₂ incubation capacity.

Roller bottle culture is one of the most important applications for this model. Roller apparatus slowly rotate cylindrical culture vessels, continually exposing adherent cells to both the growth surface and culture medium. The technique has historically been used when researchers need substantially greater culture surface area than can be obtained from conventional stationary flasks.

The Model 1927's tall interior, removable shelving, reinforced floor, and internal electrical outlets allow compatible roller bottle apparatus to operate inside the controlled CO₂ environment.

When roller apparatus is not required, the chamber can be configured with shelving for large quantities of conventional culture vessels. This makes the 1927 useful for laboratories that need to incubate many flasks, plates, dishes, or bottles simultaneously.

Cell culture laboratories may pair the SHEL LAB 1927 with biosafety cabinets for aseptic culture handling and laboratory centrifuges for cell harvesting and downstream processing. Laboratory refrigerators provide storage for media and reagents, while ultra-low temperature freezers support long-term preservation of cell banks and other biological materials.

Cell Types & Culture Applications

The SHEL LAB 1927 can support a wide range of conventional CO₂-dependent cell culture procedures, but its 40 cu. ft. chamber makes it particularly attractive for large-volume and high-throughput applications.

Common Cell Types & Applications

• Mammalian cell lines

• Adherent cell cultures

• Primary cell cultures

• Hybridoma cultures

• Vaccine research cultures

• Antibody-production workflows

• Biotechnology research cell lines

The ability to remove the standard shelves is particularly useful when configuring the chamber around roller apparatus. Researchers using powered equipment inside the 1927 should verify dimensions, electrical requirements, heat output, airflow requirements, and operating clearances for the specific equipment being installed.

Temperature, CO₂ & Environmental Stability

The SHEL LAB 1927 uses microprocessor temperature control, forced-air circulation, and automatic infrared CO₂ sensing to maintain appropriate conditions throughout its unusually large chamber.

The published operating temperature range is approximately 8°C above ambient to 60°C, providing more than enough range for conventional mammalian cell culture at approximately 37°C.

Temperature uniformity is rated at approximately ±0.5°C at 37°C under specified conditions.

Maintaining uniformity is particularly challenging in a chamber this large. SHEL LAB addresses this by directing airflow across the individual shelf levels, helping distribute conditioned air throughout the reach-in interior rather than allowing significant temperature stratification between the upper and lower portions of the chamber.

The microprocessor temperature controller provides digital setpoint and temperature display with high-resolution adjustment.

CO₂ concentration can be controlled from 0% to 20%.

Importantly, the Model 1927 uses an automatic infrared CO₂ sensor. IR sensing measures CO₂ concentration without relying on changes in the thermal conductivity of the chamber atmosphere and is therefore less affected by variations in temperature and humidity than traditional thermal conductivity sensing.

Infrared sensing also supports rapid response following door openings, helping the incubator restore the selected CO₂ concentration after cultures are accessed.

The large outer door incorporates a viewing window that allows researchers to observe the chamber interior without immediately opening the incubator. An adjustable door latch helps maintain a tight chamber seal and limit infiltration of ambient laboratory air.

Together, the forced-air system, digital temperature control, IR CO₂ sensing, and secure reach-in chamber provide the environmental stability required for both conventional and large-scale cell culture.

Large-Scale & Roller Bottle Cell Culture

One of the strongest reasons to choose a refurbished SHEL LAB 1927 is its suitability for roller bottle cell culture and other large-scale workflows.

Period documentation for the Model 1927 specifically identifies roller apparatus as a design consideration. The reinforced chamber floor provides a stable surface for compatible equipment, while the removable shelving allows the tall interior to be opened up when large apparatus is installed.

The chamber's five internal electrical outlets further support these applications by providing power inside the controlled environment.

For laboratories using roller bottles, this arrangement can provide significantly greater culture surface area than conventional flasks while keeping the entire apparatus within a controlled temperature and CO₂ atmosphere.

The same chamber flexibility can be useful for other equipment-intensive workflows. Laboratories should account for the heat produced by powered equipment, however. Unlike newer specialized shaker-ready reach-in incubators with active refrigeration, the Model 1927 is fundamentally a heated dry CO₂ incubator. Equipment that generates substantial heat can therefore affect chamber temperature and should be evaluated before use.

This is an important distinction when comparing the vintage 1927 with newer reach-in CO₂ incubators designed specifically around high internal heat loads.
