Continuous or timed operation from 0.1 minute to 999 hours
Showing 6 of 6
MaxQ 4000 benchtop orbital shakers are durable and easy to use with a spacious 18 × 18 in. platform for higher vessel capacity. These benchtop units handle up to six 2L flasks. The clear, scratch-resistant lid allows unobstructed sample viewing without disturbing chamber temperature.
Triple eccentric drive delivers uniform motion with 0.75 in. (19mm) circular orbit
Timed or continuous-run modes
Clear, scratch-resistant lid for sample viewing
Safety interlock stops platform when lid is opened
Precisely monitor temperature and control chamber temperature over complete range with ±0.1C accuracy at 37°C with PID temperature controller
Over temperature safety feature with independent thermostat provides additional backup by controlling heat if main temperature controller fails
Speed control from 40 to 400rpm by rotary dial
Integrated tachometer monitors and displays speed in rpm to guarantee an accurate setting
Easy-to-read LED digital temperature display
Continuous and timed operation from 1 to 60 min.
Variable speed control from 15 to 500 rpm
View speed, temperature and time simultaneously on three individual LED displays which helps minimize errors in establishing running conditions
Continuous and timed operation from 0.1 hr. up to 999 hr. or 0.1 min. to 999 min.
Shaker shutdown 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 and visual/audible alarms signal until condition is corrected
Soft-start feature eliminates sudden starts and stops, splashing of vessel contents or wetting of flask closure
Solid-state DC brushless motor is maintenance free
