Overview

The New Brunswick I26 is designed for laboratories that require the capacity and durability of a large incubated shaker while also benefiting from a stackable configuration. Up to three compatible units can be stacked, allowing laboratories to establish multiple independently controlled shaking environments without requiring the floor space of three separate conventional systems.

At the center of the I26 is New Brunswick's heavy-duty triple-eccentric counterbalanced drive. This drive architecture has been widely used across the manufacturer's larger shaker platforms and is designed to provide smooth orbital motion while supporting substantial operating loads.

Digital controls allow users to establish shaking speed, chamber temperature, and timed operation. The enclosed chamber provides a controlled heated environment, while safety and alarm functions help alert users to operating conditions that deviate from established parameters.

The manufacturer's 34 lb load specification includes the platform, clamps, glassware, and vessel contents. Actual vessel capacity depends on the platform and accessories installed on the individual shaker, as well as vessel dimensions, working volume, load distribution, and operating speed.

Common Applications

The New Brunswick I26 is well suited for bacterial and yeast culture, recombinant protein expression, plasmid production, microbial growth studies, seed culture preparation, media optimization, fermentation research, strain development, extraction procedures, and other laboratory processes requiring controlled heating and continuous orbital agitation.

Its combination of a large platform and 1-inch orbit makes the I26 particularly useful for shake-flask culture applications where vigorous liquid movement and aeration are required.

Ideal Laboratory Types

The I26 is appropriate for biotechnology and biopharmaceutical companies, microbiology laboratories, molecular biology groups, protein-expression facilities, fermentation and process-development laboratories, academic research facilities, university core laboratories, food and beverage research facilities, and industrial research or quality-control environments.

Stackability can be especially valuable for laboratories that need several independently controlled culture conditions but have limited available floor space.

Temperature Control & Orbital Shaking Performance

The New Brunswick I26 provides orbital shaking from 25 to 400 rpm when used as a single unit. When two or three I26 shakers are stacked, the manufacturer specifies a reduced operating range of 25 to 250 rpm to maintain stable operation.

The 1-inch / 2.5 cm orbit provides substantial liquid movement for microbial culture and general mixing applications. Shaking intensity and oxygen transfer will also depend on vessel geometry, working volume, flask baffling, platform arrangement, and operating speed.

The non-refrigerated I26 maintains temperatures from approximately 5°C above ambient to 60°C. Microprocessor feedback control provides precise regulation, with specified control accuracy of ±0.1°C between 30°C and 40°C and ±0.5°C across the remainder of the operating range.

The triple-eccentric counterbalanced drive is one of the defining features of this New Brunswick design. Combined with a solid-state brushless DC motor, the system is engineered to provide smooth orbital motion while minimizing vibration and supporting extended operation.

Platform, Flask & Vessel Compatibility

The I26 uses a large 30 × 18-inch shaking platform and can be configured with a variety of clamps, racks, and other accessories for different laboratory vessels.

Actual vessel capacity should be determined from the specific platform and accessories supplied with the individual unit rather than from theoretical manufacturer flask counts. Universal platforms, dedicated platforms, custom arrangements, clamp sizes, flask geometry, working volume, and required spacing can substantially change real-world capacity.

The manufacturer's published 34 lb maximum-load basis also includes the platform, clamps, glassware, and contents rather than referring only to the samples placed on top of the platform.

American Instrument Exchange can confirm the platform and accessories included with an individual I26. Laboratories planning to use specific Erlenmeyer flasks, Fernbach flasks, bottles, tubes, or other vessels should verify compatibility before purchase.

Refurbishment & Testing

Used New Brunswick I26 incubator shakers from American Instrument Exchange are inspected and tested prior to shipment. The shaking mechanism is operated to verify reliable orbital movement and proper operation of the speed controls, while the chamber is tested to evaluate heating and temperature regulation.

AIE technicians use external temperature-measurement equipment to verify chamber performance independently of the shaker's displayed temperature. Applicable controls, alarms, timer functions, door safety features, motor operation, and other mechanical and electrical systems are also evaluated.

Hardware or components are replaced as necessary, and the shaker is cleaned and cosmetically prepared as appropriate prior to shipment. Customers with specific testing requirements can discuss them with American Instrument Exchange before purchase.

Shipping & Installation

The New Brunswick I26 is a substantial laboratory shaker measuring approximately 50 inches wide by 30 inches deep by 27 inches high. Adequate space should be provided for the instrument itself, door operation, ventilation, electrical connections, and service access.

The unit should be installed on a stable and level surface. Proper leveling and balanced platform loading are particularly important when operating large orbital shakers at higher speeds.

Compatible I26 units can be stacked to conserve laboratory floor space. However, stacking changes the permissible operating conditions: when two or three units are stacked, shaking speed is limited to a maximum of 250 rpm. Proper manufacturer-compatible stacking hardware and installation procedures should be used.

Electrical requirements and the physical configuration of the specific AIE unit should be confirmed before installation.

Related Equipment

Laboratories using the New Brunswick I26 may also require incubators, CO2 incubators, centrifuges, laboratory refrigerators, laboratory freezers, and ultra-low freezers. American Instrument Exchange supplies used and refurbished laboratory equipment for biotechnology, pharmaceutical, academic, clinical, and industrial laboratories.
