Barnstead/Lab-Line MaxQ* 4000 Incubated and Refrigerated Shakers

Choose from three temperature ranges to fulfill a variety of molecular biology, cell and insect culture, and entomology studies. Clear lid allows you to view samples without disturbing
internal temperature.
Operation
. Shakers feature a triple eccentric drive that handles heavy workloads, provides uniform agitation and enables continuous 24-hour operation even at high speeds
. Precisely monitor and control chamber temperature over
complete range with ±0.1°C accuracy at 37°C with PID
temperature controller
Analog Operating System
. DC motor and variable speed control from 40 to 400 rpm, controlled by a rotary dial
. Integrated tachometer monitors and displays speed in rpm to guarantee an accurate setting
. Easy-to-read LED digital display shows temperature
. Operate shaker in continuous mode or set timer from 1 to 60 minutes for time studies
Digital Operating System
. Solid state DC brushless motor, variable speed control from 15 to 500 rpm, and continuous and timed operation from 0.1 hour up to 99.9 hours or 0.1 minute to 99.9 minutes
. Displayed time counts up during continuous operation and down during timed runs
. View speed, operating time and temperature simultaneously on 3 individual LED displays which helps minimize errors in establishing running conditions
. Visual/audible signals alert you to temperature deviations. Heat turns off if temperature deviates ±1°C of set point
. Shaker shut down and audible/visual alarms signal if unit operates ±10% of set speed preventing shaker from walking
. 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 due to an unbalanced load
Visual/audible alarm signal until condition is corrected.
. Soft start feature eliminates splashing of vessel contents, wetting of flask closure, and helps prevent sudden starts and stops
. Set point retention retains parameters during power failure and restarts unit automatically after power is restored
. RS232 interface allows remote monitoring of speed, time and temperature
. Monitor temperature with built-in recorder jack for output to chart recorders for a permanent record
