Complete large capacity applications with ease using the Thermo Scientific™ MaxQ™ 5000 Floor-Model Shakers, versatile incubated/refrigerated units featuring an easy side-access drain system, making cleaning spills easy and retractable foot casters to easily position the shaker in the lab. These shakers also feature a foot pedal for hands-free operation and a large slanted viewing window to check progress. Ideal for cell culture, solubility studies, plasmid purification, staining and destaining, extraction procedures, protein expression and many other applications.

Key Features:
  • Easily accommodate six 4L flasks, four 6L flasks or six 2800mL Fernbach flasks
  • Wide temperature range: 10°C above ambient to 60°C on incubated models, 15°C below ambient to 60°C on refrigerated models
  • Monitor and control chamber temperature range with ±0.1°C accuracy at 37°C
  • Overtemperature safety feature with independent thermostat provides additional backup by controlling heat if main temperature controller fails
  • Triple eccentric drive handles heavy loads, uniform agitation and continuous 24 hr. operation, even at high speeds
  • Drip pan built into the chamber floor under the platform contains spills
  • Clear, scratch-resistant lid for sample viewing
  • With foot pedal for hands-free operation and retractable casters for portability
  • Optional shelf provides additional storage space and convenience when switching flasks
  • Access ports provided through side of cabinet wall for probes, thermocouples or sensors
  • Optional gassing manifold enables direct gassing into flasks for anaerobic cultures

Analog Models:

  • Easy-to-read LED digital temperature display
  • Perform timed studies with timed operation from 1 to 60 minutes or operate shaker in continuous mode

Digital Models:

  • Variable speed control from 15 to 500rpm
  • Continuous and timed operation from 0.1 hour up to 999 hours or 0.1 to 999 min.
  • View speed, time and temperature simultaneously on three separate LED digital displays
  • Visual/audible alarms alert to temperature deviations; heat turns off if temperature deviates ±1°C of setpoint
  • Shaker shutdown and audible/visual alarms signal if unit operates ±10% of set speed, preventing the shaker from walking
  • Soft-start feature eliminates sudden starts and stops, splashing of vessel contents or wetting of flask closure
  • User-adjustable speed calibration can be performed using a digital handheld tachometer, where verification is required and protocols can be standardized
  • Unbalanced load sensor stops platform motion when excess vibration is detected and visual/audible alarms signal until condition is corrected
  • Retains parameters during power failure and restarts unit automatically after power is restored
  • Solid-state DC brushless motor is maintenance-free
  • RS-232 interface allows remote monitoring of speed, time and temperature
