Jeio Tech ISF-7100 Incubated Orbital Shaker
The Jeio Tech ISF-7100 Incubated Orbital Shaker is a high-capacity floor-standing shaker designed for bacterial culture, yeast culture, recombinant protein expression, plasmid production, fermentation research, inoculum preparation, strain screening, hybridization, extraction, solubility studies, and other laboratory applications requiring controlled temperature and continuous orbital agitation.
With a large 270 L chamber, a 29.7 × 20.5-inch shaking platform, a 1-inch orbit, and temperature control from ambient +5°C to 80°C, the ISF-7100 provides laboratories with considerably more culture capacity than a conventional benchtop incubated shaker. Its broad 30–500 rpm operating range supports everything from relatively gentle mixing to demanding microbial shake-flask applications.
The ISF-7100 also handles substantial platform loads, with permissible load capacity varying according to shaking speed. Jeio Tech specifies up to 33.1 lb at 500 rpm, 55.1 lb at 400 rpm, and 77.2 lb at 350 rpm. This combination of high speed and heavy-load capability makes the ISF-7100 particularly useful for laboratories running multiple large shake flasks or scaling microbial cultures before transfer into larger fermentation systems.
A direct-drive brushless motor and triple-cam shaking mechanism provide stable orbital motion without a conventional belt-driven system. Microprocessor PID temperature and speed control, automatic tuning, multiple temperature-safety systems, programmable timing, a viewing window, interior lighting, smooth start and stop operation, automatic restart after power failure, and platform-position control add functionality for demanding research environments.
This Jeio Tech ISF-7100 is available used and refurbished from American Instrument Exchange. The unit is inspected, cleaned, and performance tested before shipment and includes a 90-day warranty from AIE.

Overview
The Jeio Tech ISF-7100 is designed for laboratories that have moved beyond the capacity of a small benchtop incubator shaker.
Its 270 L chamber provides enough space for large numbers of smaller culture vessels or multiple multi-liter flasks, allowing one instrument to support clone screening, microbial culture expansion, recombinant protein production, fermentation development, and inoculum preparation.
Unlike an open-air orbital shaker, the ISF-7100 incorporates its own heated chamber. Researchers can therefore establish both shaking speed and incubation temperature on the same instrument without placing the shaker inside a separate environmental chamber.
The combination of substantial capacity, high maximum speed, large platform area, and heavy-load operation makes the ISF-7100 particularly attractive for biotechnology, microbiology, pharmaceutical, academic, and fermentation laboratories where shake-flask throughput is a recurring limitation.

Common Applications
The Jeio Tech ISF-7100 is well suited for bacterial and yeast culture, recombinant protein expression, plasmid production, fermentation research, strain screening, media optimization, inoculum preparation, biomass production, hybridization, extraction procedures, and solubility studies.
Its capacity makes it particularly useful when experiments involve multiple cultures or larger shake-flask volumes that would quickly occupy the entire platform of a smaller incubated shaker.
Ideal Laboratory Types
The ISF-7100 is a strong fit for biotechnology companies, pharmaceutical research laboratories, microbial fermentation groups, recombinant protein laboratories, molecular biology facilities, synthetic biology companies, academic research laboratories, industrial biotechnology operations, process-development groups, and other facilities that regularly operate temperature-controlled shake-flask cultures.
It is especially valuable for growing laboratories that need substantially more culture capacity but are not yet ready to perform every experiment in a controlled bioreactor.
270 Liter High-Capacity Chamber
The ISF-7100 provides approximately 270 L, or 9.5 cubic feet, of chamber volume.
This large chamber allows researchers to use substantially larger vessel configurations than would normally fit inside a compact benchtop incubator shaker.
The generous chamber height also accommodates multi-liter Erlenmeyer and Fernbach flasks with appropriate clamps.
For laboratories running microbial cultures every day, chamber volume is more than a convenience. It directly affects the number of experiments that can be conducted in parallel and the maximum shake-flask scale that can be reached before transitioning to a bioreactor.
29.7 × 20.5-Inch Shaking Platform
The ISF-7100 uses a large 29.7 × 20.5-inch platform.
Jeio Tech offers universal platforms as well as flask clamps for numerous vessel sizes, allowing laboratories to configure the platform according to specific workflows.
A universal platform is useful when different flask sizes need to be operated simultaneously, while dedicated clamp arrangements can maximize capacity for laboratories that routinely work with one vessel size.
Customers purchasing a refurbished ISF-7100 should confirm the exact platform and clamps included with the specific unit before shipment.
Flask Capacity
With appropriate Jeio Tech clamps, the ISF-7100 platform can support a wide range of Erlenmeyer flask sizes.
Manufacturer capacity information lists up to approximately 88 × 50 mL, 68 × 100 mL, 39 × 250 or 300 mL, 28 × 500 mL, 18 × 1 L, 11 × 2 L, 8 × 2.8 L, 6 × 4 L, or 5 × 6 L flasks.
Actual usable capacity depends on the platform, clamps, vessel geometry, fill volume, and experimental requirements.
That range allows the same shaker to support high-throughput screening with numerous small vessels as well as larger-scale microbial culture in multi-liter flasks.
Up to Five 6 Liter Flasks
One of the most commercially significant capabilities of the ISF-7100 is compatibility with up to five 6 L flasks when properly configured.
This makes the shaker useful for larger-scale microbial culture, fermentation development, biomass production, protein-expression work, and inoculum preparation.
A laboratory can therefore perform meaningful scale-up within shake flasks before moving a successful process into a bioreactor.
For laboratories trying to postpone or reduce competition for fermenter capacity, the ability to run multiple multi-liter shake cultures can be especially valuable.
30–500 rpm Speed Range
The ISF-7100 provides orbital shaking from 30 to 500 rpm.
This broad range gives researchers flexibility across vessel sizes and experimental applications.
Lower speeds can support relatively gentle mixing, hybridization, extraction, or large heavily loaded vessels. Higher speeds can support microbial cultures where strong mixing and oxygen transfer are important.
Maximum allowable load decreases as shaking speed increases, so speed and vessel loading should always be considered together.
Speed and Load Relationship
The ISF-7100 is capable of carrying a total platform load up to 77.2 lb, but that specification should not be interpreted as a 77.2 lb load at 500 rpm.
Jeio Tech specifies approximately 33.1 lb maximum load at 500 rpm, 55.1 lb at 400 rpm, and 77.2 lb at 350 rpm.
This relationship reflects the greater mechanical forces generated as both shaking speed and load increase.
For laboratories running very heavy flask configurations, the appropriate operating speed should therefore be selected according to the manufacturer's permissible-load specifications.
1-Inch Orbital Motion
The ISF-7100 uses a 25.4 mm / 1-inch orbital diameter.
Orbit diameter influences how liquid moves within a culture vessel and therefore affects mixing, oxygen transfer, gas exchange, and shear.
A 1-inch orbit is well suited to many microbial culture and shake-flask fermentation applications, particularly when larger Erlenmeyer and Fernbach flasks are involved.
Researchers transferring a process from another shaker should compare both rpm and orbit diameter rather than assuming that matching rpm alone will reproduce identical mixing conditions.
Temperature Range to 80°C
The non-refrigerated ISF-7100 controls temperature from approximately 5°C above ambient to 80°C.
This range comfortably covers common bacterial and yeast culture temperatures such as 25°C, 30°C, and 37°C while also supporting elevated-temperature laboratory procedures.
Because this configuration does not contain refrigeration, it cannot actively maintain temperatures near or below room temperature.
Laboratories requiring low-temperature shaking should consider the refrigerated ISF-7100R version.
Temperature Stability & Uniformity
Jeio Tech specifies temperature fluctuation of approximately ±0.1°C in flask at 37°C and temperature variation across the chamber of approximately ±0.5°C at 37°C.
Maintaining a consistent thermal environment is important when multiple cultures are distributed across a large platform.
Temperature differences between cultures could introduce unwanted experimental variability, particularly during long incubation periods or comparative studies.
The ISF-7100 uses microprocessor PID control and temperature auto-tuning to regulate chamber conditions.
Microprocessor PID Control
PID feedback control continually adjusts heating output according to the difference between the programmed temperature and actual chamber conditions.
This approach helps the shaker reach the requested setpoint and maintain it during extended operation.
Jeio Tech also incorporates calibration functions that allow temperature performance to be checked and adjusted when appropriate.
For laboratories performing repetitive culture procedures, these controls support consistent operating conditions from one run to the next.
Direct-Drive Brushless Motor
The ISF-7100 uses a direct-drive brushless motor rather than relying on a conventional belt-driven shaker mechanism.
Direct-drive technology eliminates the drive belt as a routine wear component.
The brushless motor also eliminates motor brushes, reducing another common maintenance item.
For an incubator shaker that may operate continuously for hours or days at a time, reducing these mechanical wear components can be particularly useful.
Triple-Cam Shaking Mechanism
The direct-drive motor works with a triple-cam shaking mechanism designed to provide stable orbital motion even under substantial platform loads.
Large culture vessels filled with several liters of medium can generate significant dynamic forces during orbital shaking.
A robust drive design is therefore especially important in high-capacity systems like the ISF-7100.
The platform also uses automatic speed adjustment and imbalance monitoring to respond to operating conditions that could create excessive vibration or instability.
Smooth Start & Stop
The ISF-7100 gradually accelerates and decelerates the shaking platform.
Smooth startup helps reduce abrupt vessel motion and the potential for liquids to splash toward flask closures.
Controlled deceleration provides similar benefits when a run ends or the shaker is stopped.
This feature becomes increasingly useful as flask sizes and liquid volumes increase.
Automatic Load & Imbalance Monitoring
The shaker monitors conditions associated with excessive load, imbalance, vibration, or external disturbance.
When unstable conditions are detected, the system can automatically adjust operation or stop the shaking mechanism as appropriate.
This helps protect the drive system and reduces the possibility that a badly unbalanced load will continue shaking unattended.
Researchers should still distribute vessels as evenly as practical across the platform before beginning a run.
Bacterial Culture
The ISF-7100 is particularly well suited to bacterial shake-flask culture.
Applications include E. coli culture for cloning, plasmid production, recombinant protein expression, strain screening, synthetic biology, metabolic engineering, and general microbiology.
The ability to accommodate anything from dozens of small flasks to several multi-liter vessels makes the shaker useful through multiple stages of a bacterial culture workflow.
Recombinant Protein Expression
Microbial recombinant protein production frequently requires temperature-controlled orbital shaking for many hours.
Researchers may begin by screening multiple clones or expression conditions in small cultures, then expand promising candidates into progressively larger shake flasks.
The ISF-7100 can support both stages on the same instrument.
Its large platform and compatibility with vessels up to 6 L make it particularly useful when moving beyond small expression screens toward larger biomass production before protein purification.
Plasmid Production
Bacterial plasmid workflows commonly require overnight shake-flask cultures before DNA extraction.
The ISF-7100 can support large numbers of small or medium cultures simultaneously, making it useful for molecular biology laboratories processing many plasmid preparations.
Larger shake flasks can also support higher-volume plasmid production when more bacterial biomass is required.
Yeast Culture
The ISF-7100 is also appropriate for yeast culture, including recombinant protein expression, strain engineering, metabolic research, fermentation development, and general microbiology.
Its broad speed and temperature ranges provide flexibility for yeast protocols that differ from routine bacterial culture.
Multiple shaker settings can be selected according to organism, vessel size, fill volume, and required oxygen transfer.
Fermentation & Process Development
Shake flasks remain an important tool during early fermentation development.
Researchers can compare strains, growth media, temperatures, nutrient conditions, induction strategies, and other process variables before moving into a controlled bioreactor.
The ISF-7100's large platform allows many experimental conditions to be evaluated in parallel.
Once a process is selected, larger flasks can support scale-up and inoculum development before transfer into fermentation equipment.
Inoculum Preparation
Bioreactors often require a series of progressively larger seed cultures before the main vessel can be inoculated.
The ISF-7100 can support this process by allowing researchers to move from small flasks into larger multi-liter cultures while maintaining controlled temperature and orbital agitation.
Compatibility with 2 L, 2.8 L, 4 L, and 6 L vessels makes the shaker particularly useful during later seed-train stages.
Hybridization, Extraction & Solubility Studies
Jeio Tech also identifies hybridization, extraction, and solubility studies among appropriate applications for its incubated shakers.
These procedures can require both sustained temperature control and orbital movement over extended periods.
The ISF-7100's temperature range to 80°C broadens its usefulness beyond conventional microbial culture and allows a single instrument to support several departments or research programs within a laboratory.
Three Operating Modes
The ISF-7100 can operate with temperature and shaking together, temperature control alone, or shaking alone.
This flexibility allows the chamber to be used for more than one type of workflow.
For example, researchers can run a normal temperature-controlled shake-flask culture, use orbital agitation without heating when ambient conditions are suitable, or use temperature control without platform motion for appropriate static incubation procedures.
Long-Duration Timer
The timer can be programmed from approximately one minute to 999 hours and 59 minutes.
This broad range supports both relatively short experimental procedures and multi-day cultures.
Continuous operation can also be used when experiment duration is determined manually rather than by a preset endpoint.
Automatic Restart After Power Failure
The ISF-7100 can resume operation after power is restored following an interruption.
This is useful for overnight cultures and extended experiments where a brief electrical outage could otherwise leave samples without shaking or controlled incubation for the remainder of the run.
Critical cultures should still be protected through appropriate facility alarms, backup power, or independent monitoring where warranted.
Platform Return Position
The shaker can automatically return its platform to a repeatable starting position after operation stops.
This feature improves access to samples and can be useful for workflows involving repeated manual or automated sampling and dosing.
It is particularly convenient on a large platform where researchers may need consistent access to specific vessel locations.
Viewing Window & Interior Lighting
A large viewing window allows researchers to inspect the chamber without fully opening the lid.
Interior LED lighting improves visibility of cultures and vessel positions.
Reducing unnecessary chamber opening can help limit disturbance to the controlled internal environment during an experiment.
Temperature Safety Systems
The ISF-7100 incorporates multiple independent temperature-monitoring and protection mechanisms.
High and low temperature deviation alarms notify users when operating conditions move outside expected limits, while electronic and mechanical over-temperature protection provide additional safeguards against excessive heating.
These controls are particularly important for unattended or long-duration incubation procedures.
ISF-7100 vs. ISF-7100R
The ISF-7100 is a heated incubated shaker without active refrigeration.
Its temperature range begins approximately 5°C above ambient and extends to 80°C.
The ISF-7100R adds refrigeration and can operate approximately 20°C below ambient, with a specified minimum of 4°C.
For routine bacterial and yeast culture at 30°C or 37°C, the non-refrigerated ISF-7100 generally provides the required temperature range.
Researchers performing low-temperature induction or other below-ambient procedures should consider a refrigerated model.
ISF-7100 vs. ISF-7200
The ISF-7100 and ISF-7200 share the same large 270 L chamber and 29.7 × 20.5-inch platform but use different orbital diameters.
The ISF-7100 uses a 1-inch orbit and can operate up to 500 rpm.
The ISF-7200 uses a larger 2-inch orbit and operates over a lower speed range.
The appropriate model depends on vessel size, process requirements, oxygen-transfer needs, and the conditions under which an existing protocol was developed.
ISF-7100 vs. Thermo MaxQ 6000
Both instruments combine orbital shaking with controlled heated incubation, but the ISF-7100 provides substantially more platform area and chamber volume.
Its 29.7 × 20.5-inch platform, 270 L chamber, heavy-load capability, and support for multi-liter flasks make it particularly attractive for large-scale microbial culture.
The MaxQ 6000 can be a strong choice for laboratories requiring a smaller incubated shaker footprint, while the ISF-7100 is oriented toward higher-capacity culture and process-development work.
ISF-7100 vs. New Brunswick I26
The New Brunswick I26 and Jeio Tech ISF-7100 both serve laboratories requiring larger incubated-shaker capacity.
The I26 offers a 30 × 18-inch platform and was designed for vertical stacking of multiple units.
The Jeio Tech ISF-7100 provides a larger 270 L chamber, a 29.7 × 20.5-inch platform, operation up to 500 rpm, and compatibility with vessels as large as 6 L.
The better choice depends on whether a laboratory prioritizes vertical stacking or large single-chamber flask capacity and high-speed operation.
