Overview

The Thermo Scientific MaxQ 4000 combines the functionality of an orbital shaker and heated incubator in a relatively compact benchtop system. Its enclosed chamber maintains elevated temperatures while the orbital drive provides continuous agitation for flasks and other laboratory vessels.

The digital MaxQ 4000 provides independent displays for speed, operating time, and chamber temperature, allowing researchers to monitor all three parameters simultaneously. Speed can be adjusted in 1 rpm increments, while timed or continuous operation accommodates both short mixing procedures and extended culture experiments.

A solid-state DC brushless motor drives the orbital mechanism, reducing maintenance associated with conventional brush-type motors. The shaker also incorporates safeguards designed for unattended operation, including speed deviation alarms, temperature alarms, an independent over-temperature safety system, and a lid interlock that stops platform motion when the chamber is opened.

The clear chamber lid allows samples to be visually inspected without repeatedly disturbing the controlled internal environment.

Platform dimensions and published flask capacities should not be assumed to describe every used MaxQ 4000. Actual vessel capacity depends on the platform, clamps, racks, custom fixtures, vessel geometry, working volume, and accessories installed on the individual unit.

Common Applications

The Thermo MaxQ 4000 is well suited for bacterial and yeast culture, recombinant protein expression, plasmid purification, microbial growth studies, cell culture applications, solubility studies, extraction procedures, hybridization, staining and destaining, washing procedures, bacterial suspensions, and general laboratory mixing.

Its combination of a broad shaking-speed range and controlled heating makes the MaxQ 4000 particularly useful for laboratories running extended culture experiments where both temperature and agitation must remain stable.

Ideal Laboratory Types

The MaxQ 4000 is appropriate for biotechnology and pharmaceutical laboratories, microbiology facilities, molecular biology groups, protein-expression laboratories, fermentation and process-development groups, academic research facilities, university core laboratories, food and beverage research laboratories, and industrial research or quality-control environments.

Its benchtop format can be particularly useful for laboratories that need the capabilities of a full incubator shaker but do not have the floor space required for a larger floor-standing system.

Temperature Control & Orbital Shaking Performance

The digital Thermo MaxQ 4000 provides orbital shaking from 15 to 500 rpm with speed control accuracy of ±1 rpm. Its 0.75-inch / 1.9 cm orbit provides effective liquid movement for microbial culture, mixing, extraction, and other laboratory applications.

The standard incubated MaxQ 4000 operates from approximately 10°C above ambient to 60°C. Thermo specifies temperature accuracy of ±0.1°C at 37°C in flask and temperature uniformity of ±0.5°C at 37°C.

Speed, temperature, and operating time are shown on separate digital displays, allowing all three parameters to be monitored without switching between display modes. Nonvolatile memory maintains programmed speed and time settings following a power interruption and automatically reactivates them when power is restored.

The shaker also monitors operating speed. If speed deviates significantly from the selected setpoint, the digital system can generate audible and visual warnings and shut down shaking operation. An unbalanced-load condition can similarly trigger an alarm and stop the shaker until the load is corrected.

As with any orbital shaker, actual culture performance depends on the interaction between rpm, orbit diameter, flask geometry, baffling, working volume, platform arrangement, and the physical characteristics of the culture or solution.

Platform, Flask & Vessel Compatibility

Thermo designed the MaxQ 4000 to accept different platform configurations. Factory options include an 18 × 18-inch universal platform that can be fitted with a mixture of clamps as well as dedicated platforms supplied with predetermined clamp arrangements.

This flexibility is useful for laboratories working with different vessel sizes, but it also means that there is no single flask-capacity specification that should automatically be assigned to every MaxQ 4000.

Thermo literature describes configurations capable of holding multiple large culture flasks, but actual capacity depends on the platform installed on the individual shaker, clamp sizes and positions, vessel dimensions, working volumes, load distribution, and any custom modifications or accessories.

The manufacturer specifies a maximum rated load of 50 lb / 22.7 kg. This load rating should not be interpreted as a guarantee that a particular number or arrangement of vessels will fit on the specific AIE unit.

American Instrument Exchange can confirm the platform and accessories included with an individual MaxQ 4000. Customers planning to use particular Erlenmeyer flasks, Fernbach flasks, bottles, tubes, or other vessels should verify compatibility before purchase.

Refurbishment & Testing

Used Thermo Scientific MaxQ 4000 incubated shakers from American Instrument Exchange are inspected and tested prior to shipment. The shaking mechanism is operated for extended periods to verify reliable orbital movement and proper operation at applicable speed setpoints.

Because the MaxQ 4000 is an incubated shaker, AIE also evaluates the heating and temperature-control system. An external digital temperature probe is used to verify chamber temperature independently of the shaker's displayed reading.

Testing includes evaluation of the orbital drive, digital speed controls, temperature controls, timer, displays, alarms, lid safety interlock, motor operation, and other applicable mechanical and electrical components. The shaker is also cleaned and cosmetically prepared as appropriate prior to shipment.

Customers with specific testing requirements are encouraged to discuss them with American Instrument Exchange before shipment. While AIE cannot duplicate every analytical or biological application, operating conditions can be simulated when practical to help verify the equipment for its intended use.

Shipping & Installation

The standard MaxQ 4000 measures approximately 32 inches long by 22.5 inches wide by 22 inches high, with an internal chamber measuring approximately 20 × 21 × 13 inches.

Although Thermo classifies the MaxQ 4000 as a benchtop shaker, its size, weight, and operating load require a substantial laboratory bench or other stable support. The installation surface should be level and capable of safely supporting the shaker, platform, accessories, vessels, and contents.

Adequate clearance should be provided for opening the chamber lid, ventilation, electrical connections, and service access. Vessel height and platform configuration should also be considered to ensure adequate clearance inside the chamber during orbital movement.

This AIE unit is configured for 120 V, 50/60 Hz electrical service.

Related Equipment

Laboratories using the Thermo Scientific MaxQ 4000 may also require incubators, CO2 incubators, centrifuges, laboratory refrigerators, laboratory freezers, ultra-low freezers, water baths, and other laboratory shakers. American Instrument Exchange supplies used and refurbished laboratory equipment for biotechnology, pharmaceutical, academic, clinical, and industrial research laboratories.
