Barnstead MaxQ 4450 Digital Orbital Incubator Shaker
The Barnstead MaxQ 4450 Digital Orbital Incubator Shaker combines orbital shaking technology with a small footprint benchtop design for a versatile shaker ideal for cell culture, solubility studies, extraction procedures, protein expression, and many other applications. The MaxQ 4450 features shaking speeds from 15 to 500 RPM around a 0.75 inch orbit with a temperature range of 5C above ambient to 80C. Includes 11 x 13 inch platform for vessel capacity up to four 1L flasks. The MaxQ 4450's clear, scratch-resistant lid allows for unobstructed sample viewing without disturbing the chamber. PID temperature controller provides 0.1C temperature accuracy at 37C, and an independent over temperature feature provides a backup temperature controller for added safety. This incubator shaker will be fully tested to perform at factory specifications before being shipped.
The Barnstead MaxQ 4450 Digital Orbital Incubator Shaker includes:
- > 11" x 13" Platform
- > NIST Calibration and Preventative Maintenance Report
- > Power Cord
- > Operator's Manual
- > Full 180 Day Parts and Labor Warranty

- 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.
