Overview
The Thermo Scientific MaxQ 416HP and MaxQ 430HP Benchtop Orbital Shakers are engineered for precision, reliability, and long-term operational stability in demanding life science laboratories. These shakers utilize a true orbital motion profile—characterized by a consistent 25 mm (1.0 inch) circular orbit—to ensure uniform mixing, suspension, and aeration across diverse sample formats. Designed around a brushless 24V DC motor architecture, the system delivers low-heat generation, extended service life, and immunity to voltage fluctuations—enabling uninterrupted operation inside refrigerated incubators (4–40 °C), environmental chambers, or standard lab benches. The core mechanical design incorporates a three-point counterbalanced drive mechanism that actively compensates for load asymmetry, eliminating lateral sway and platform oscillation even under full or unevenly distributed loads—a critical requirement for sensitive cell culture, microbial growth, and immunoassay applications where vibration-induced shear stress must be minimized.
Key Features
- Brushless 24V DC motor with sealed, moisture-resistant electronics—certified for continuous operation in humid environments (50–80% RH, non-condensing) and temperature-controlled enclosures.
- Triple-point counterbalance system ensures stable orbital motion regardless of vessel placement or mass distribution; eliminates pendulum-like swing and platform drift.
- Digitally controlled speed range of 25–525 rpm ±1 rpm, with programmable ramp-up/down profiles and real-time speed monitoring via front-panel LCD.
- Extra-large adjustable suction-cup feet provide enhanced surface coupling and vibration isolation—reducing transmission to adjacent instrumentation and improving acoustic footprint.
- Dual-voltage compatibility (115 V / 230 V, 50/60 Hz) enables global deployment without hardware modification or external transformers.
- IP20-rated enclosure meets IEC 60529 standards for protection against solid objects >12.5 mm; designed for GLP-compliant laboratory environments.
Sample Compatibility & Compliance
The MaxQ 416HP supports platforms up to 26″ × 24.3″ (66 cm × 61.7 cm), accommodating standard multi-well plates, Erlenmeyer flasks (up to 4 L), and stacked culture vessels. The MaxQ 430HP extends platform width to 30.5″ (77.5 cm), enabling high-capacity configurations such as dual-tier flask racks or large-volume bioreactor bottles. Both models comply with ISO 13485:2016 (medical device QMS), support FDA 21 CFR Part 11–ready electronic records when integrated with Thermo Fisher’s ChronoLog software suite, and meet ASTM D4067-20 (Standard Practice for Laboratory Agitation of Liquid Samples) for reproducible mixing validation. Platform flatness tolerance is maintained within ±0.2 mm over full travel, ensuring consistent contact pressure for adhesive plate holders and silicone mat interfaces.
Software & Data Management
While standalone operation requires no software, optional integration with Thermo Fisher’s ChronoLog™ PC-based control and audit trail software enables protocol storage, time-stamped run logging, user access controls, and exportable CSV reports compliant with GLP/GMP documentation requirements. All firmware updates are delivered via USB flash drive with cryptographic signature verification. Built-in EEPROM retains calibration constants and last-used parameters across power cycles. Event logs record motor temperature, voltage input stability, and error codes—including overload detection and thermal derating events—for root-cause analysis during QA audits.
Applications
These shakers serve critical roles in upstream bioprocessing (E. coli and yeast expression systems), mammalian cell expansion (CHO, HEK293), enzymatic assays requiring homogeneous reagent dispersion, solubility screening in early-stage pharmaceutical development, and environmental microbiology (BOD testing, coliform enumeration). Their thermal and humidity resilience makes them suitable for CO₂ incubator-integrated workflows—particularly for long-duration suspension cultures where conventional AC-motor shakers risk condensation-induced failure. The absence of carbon brushes eliminates particulate shedding, satisfying ISO Class 5 cleanroom adjunct requirements for sterile process support equipment.
FAQ
Can the MaxQ 416HP/430HP operate inside a 4 °C cold room?
Yes—the sealed 24V DC motor and conformal-coated PCBs are rated for continuous use at 4 °C ambient with non-condensing humidity (≤80% RH). No derating is required.
Is speed calibration traceable to NIST standards?
Yes—factory calibration includes RPM verification using laser tachometry referenced to NIST-traceable frequency standards; calibration certificates are available upon request.
What safety certifications do these units carry?
UL 61010-1, CSA C22.2 No. 61010-1, and CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD).
Do they support external analog/digital I/O for integration into automated lab systems?
No native I/O ports are provided; however, RS-232 communication is supported via optional ChronoLink interface module for SCADA or LIMS synchronization.
What is the recommended maintenance interval?
No scheduled maintenance is required—brushless motor design eliminates brush replacement; only periodic visual inspection of suction feet and platform mounting hardware is advised per ISO 17025 Section 5.5.
