    Combine incubated and refrigerated temperatures with a small footprint by using Thermo Scientific™ MaxQ™ 4450 Benchtop Orbital Shakers. These versatile shakers are ideal for incubating a small number of vessels and are used for cell culture, solubility studies, extraction procedures, protein expression and many other applications.

    Key Features:

    • Clear, scratch-resistant lid allows unobstructed sample viewing without disturbing chamber temperature
    • Chamber holds four 1L flasks
    • Choose from two temperature ranges: incubated (5°C above ambient to 80°C) or with a cooling coil option that requires a chiller (5°C below ambient to 80°C)
    • Monitor and control chamber temperature range with ±0.1°C accuracy at 37°C
    • Triple eccentric drive handles heavy loads, uniform agitation and continuous 24-hour operation, even at high speeds
    • Overtemperature safety feature with independent thermostat provides additional backup by controlling heat if main temperature controller fails
    • Interlock stops platform when lid is opened

    Analog Models:

    • Speed is controlled by a rotary dial, monitored accurately by a traditional tachometer
    • Easy-to-read LED digital temperature display
    • Speed: 40-400rpm Integrated tachometer monitors and displays speed in rpm to guarantee an accurate setting
    • Timed: 1 to 60 min. or continuous

    Digital Models:

    • Three individual LED displays: speed, time and temperature
    • 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.
    • Shaker shutdown and audible/visual alarms signal temperature deviations or if unit operates ±10% of set speed, preventing shaker from walking
    • Soft-start feature eliminates sudden starts and stops, splashing of vessel contents or wetting of flask closure
    • Set point retention retains parameters during power failure and restarts unit automatically after power is restored
    • Solid-state DC brushless motor is maintenance-free

    Operating Chiller:

    • Provides a refrigerated atmosphere
    • For plasmid purification and protein expression in bacteria for use with MaxQ 4450 with cooling coil option
    • Achieve temperature ranges from 20° to 30°C

    Ordering Information:

    For a complete system, order platforms and clamps (sold separately).


    Universal Platform (without clamps) or Dedicated Platform (with pre-installed clamps). All MaxQ 4450 shakers with cooling coil require a chiller sold separately.

    Recommended for:

    • Cell culture
    • Solubility studies
    • Extraction procedures
    • Plasmid purification
    • General mixing
    • Bacterial suspensions
    • Staining and destaining
    • Washing procedures
    • Hybridizations
    • Protein expression in bacteria
