Thermo Scientific MaxQ™ 6000 Incubated/Refrigerated Stackable Orbital Shaker

Overview

The Thermo Scientific MaxQ™ 6000 Incubated/Refrigerated Stackable Orbital Shaker is an engineered solution for laboratories requiring precise temperature-controlled agitation of biological and biochemical samples in space-constrained environments. Designed around orbital shaking mechanics—where platform motion follows a consistent circular path with a fixed 1.9 cm diameter orbit—the instrument delivers uniform mixing, suspension, and aeration across culture flasks, tubes, and multi-well plates. Unlike reciprocating or vortex shakers, orbital motion minimizes shear stress on sensitive cell cultures while ensuring high reproducibility in growth kinetics and expression studies. The integrated refrigeration and heating system enables stable thermal control from ambient +10°C up to 60°C, supporting applications ranging from mesophilic bacterial cultivation to thermosensitive protein expression protocols. Its stackable architecture—certified for two-unit vertical configuration without structural reinforcement—reduces footprint by up to 50% compared to side-by-side placement, making it suitable for core facilities, bioprocessing labs, and GLP-compliant QC environments where floor space optimization is critical.

Key Features

• Stackable dual-unit design validated for safe, vibration-isolated operation at two-tier height (up to 205.8 cm total), with optional adapter kit enabling synchronized control of two independent 45.7 × 45.7 cm platforms
• Digital microprocessor-based controller with real-time display of setpoint and actual values for speed (15–500 rpm, ±1 rpm accuracy) and temperature (±0.3°C stability over full range)
• Brushless DC motor delivering maintenance-free operation, low electromagnetic interference, and consistent torque across load conditions up to 15.9 kg
• Corrosion-resistant stainless-steel platform compatible with aqueous, acidic, and alcohol-based cleaning agents; designed for long-term exposure to humid incubation environments
• Programmable timer supporting continuous mode or timed operation from 0.1 minute to 999 hours with auto-shutdown and audible alert
• Integrated safety systems including overtemperature cutoff, motor overload protection, and door-open detection (for models with enclosure option)

Sample Compatibility & Compliance

The MaxQ™ 6000 accommodates standard labware including Erlenmeyer flasks (up to 4 L), Fernbach flasks, roller bottles, deep-well plates, and tube racks—secured via non-slip silicone mat or custom clamping accessories. Its thermal performance meets ISO 13485 requirements for medical device manufacturing support, and temperature uniformity across the platform complies with ASTM E145-22 Class II specifications for laboratory ovens and incubators. Electrical certification includes UL 61010-1, CAN/CSA C22.2 No. 61010-1, and CE marking per EU Directive 2014/30/EU (EMC) and 2014/35/EU (LVD). The unit supports audit-ready documentation for FDA 21 CFR Part 11 compliance when paired with Thermo Fisher’s ChronoLog™ software suite (sold separately), providing electronic signatures, change tracking, and secure user access levels.

Software & Data Management

While the MaxQ™ 6000 operates autonomously via front-panel controls, it supports optional RS-232 and Ethernet connectivity for integration into centralized lab management systems. When connected to ChronoLog™ or third-party SCADA platforms, users can remotely monitor runtime parameters, export timestamped CSV logs (speed, temp, elapsed time), and trigger alarms via email or SNMP traps. All data records include embedded metadata: instrument ID, operator login, calibration status, and environmental timestamp (NTP-synchronized). Audit trails are retained for ≥18 months and comply with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) as defined in WHO TRS 996 Annex 11 and EU GMP Annex 11 guidelines.

Applications

• Mammalian and insect cell culture expansion under controlled O₂/CO₂-compatible enclosures (when used with optional chamber)
• Microbial fermentation screening across temperature gradients (e.g., E. coli expression at 30°C vs. 37°C)
• Enzyme kinetics assays requiring simultaneous agitation and thermal stabilization
• Antibiotic susceptibility testing using broth microdilution formats
• Hybridization and washing steps in nucleic acid purification workflows
• Stability studies for biologics under ICH Q5C accelerated conditions (e.g., 25°C/60% RH equivalent via controlled air exchange)

FAQ

Can the MaxQ™ 6000 operate unstacked while maintaining full speed range?
Yes. When used individually, the shaker achieves 15–500 rpm. Stacking reduces maximum speed to 15–300 rpm to ensure mechanical stability and thermal uniformity across both units.

Is external refrigeration water required for cooling below ambient?
No. The unit incorporates a sealed, compressor-based refrigeration system with R290 refrigerant; no chilled water loop or external coolant is needed.

What is the temperature uniformity specification across the platform?
At 37°C setpoint, measured uniformity is ≤ ±0.5°C (9-point grid per ASTM E145-22); at 60°C, uniformity is ≤ ±0.8°C.

Are validation documents (IQ/OQ/PQ) available?
Yes. Thermo Fisher provides factory-verified Installation Qualification (IQ) and Operational Qualification (OQ) protocols; Performance Qualification (PQ) templates are customizable for site-specific media and load configurations.

Does the shaker support GMP-compliant user access control?
When integrated with ChronoLog™ software, role-based permissions (e.g., operator, supervisor, administrator) and electronic signature capture are enabled per 21 CFR Part 11 Subpart B requirements.
