    • 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
