Thermo Scientific MaxQ 4450 Digital Orbital Incubator Shaker w/ Cooling Coil

Features

• Adjustable parameters via membrane keypad with fine incremental control
• Non-volatile memory retains settings during power interruptions and automatically resumes operation
• Flashing display alerts users to power loss events for added process awareness
• Integrated cooling coil enables below-ambient operation when paired with an external chiller
• Drive interrupt safety feature stops shaking when the lid is opened
• Independent over-temperature protection with visual alarm for enhanced sample safety
• Audible and visual alarms notify users of deviations or unbalanced operating conditions
• Automatic shutdown of shaking function during fault conditions until corrected
• Solid-state brushless DC motor ensures reliable, low-maintenance operation
• Audible alarm muting function allows temporary silencing without disabling alerts
• Timer supports both continuous operation and extended timed runs for flexible workflows

The Thermo Scientific MaxQ 4450 Digital Orbital Incubator Shaker w/ Cooling Coil combines precise environmental control with reliable orbital shaking in a compact benchtop design, making it ideal for applications such as cell culture, protein expression, extraction procedures, and solubility studies. Designed for versatility, this model supports both incubated operation and below-ambient temperature workflows when paired with an external chiller.

A PID microprocessor controller allows users to accurately regulate speed, temperature, and time through an intuitive keypad interface, with adjustments available in fine 1 RPM increments. The digital display provides clear system feedback and alerts users to power interruptions, while non-volatile memory preserves setpoints and automatically resumes operation once power is restored.

For enhanced performance, the integrated cooling coil enables operation below ambient conditions when connected to a compatible chiller, expanding the range of applications supported within a single unit. Safety features include a lid-open drive interrupt that immediately stops shaking and an independent over-temperature protection system with visual alerts to safeguard samples.

Built for dependable, everyday use, the MaxQ 4450 offers straightforward operation, precise control, and flexible temperature capabilities, making it a practical solution for laboratories requiring consistent incubation and shaking performance.

All of our equipment is fully tested to perform at factory specifications before being shipped.

Inspection and Recertification Checklist

• Examine the chamber glass for cracks or chips, replacing it as needed to maintain structural integrity.
• Inspect door seals for signs of wear or damage, replacing them to ensure a tight seal.
• Check the display for brightness and clarity, replacing any dim or dead pixels to maintain optimal visibility.
• Test all buttons to confirm full functionality and consistent responsiveness.
• Replace all platform assembly bearings to ensure smooth and reliable motion.
• Inspect the drive belt for wear, replacing it if torn or cracked to maintain performance.
• Examine all wiring for frays, tears, or breakages, addressing any issues for electrical safety.
• Verify each PCB test point, replacing any malfunctioning components to ensure system reliability.
• Check drive belt tension to confirm correct alignment and function.
• Confirm the compressor’s operation, cleaning condenser filter and fins for efficient cooling.
• Calibrate internal temperature accuracy using an NIST-traceable temperature probe.
• Measure and calibrate platform RPMs with an NIST-traceable tachometer to ensure precision.
• Conduct a final cosmetic inspection to verify all surfaces meet appearance standards.
