Thermo Scientific MaxQ 4000 Large Incubated Orbital Shaker Model 4328

Combine the convenience of a benchtop design with orbital shaking technology in one package with Thermo Scientific™ MaxQ™ 4000 Benchtop Orbital Shakers. Versatile, incubated and refrigerated, these shakers are ideal for cell culture, solubility studies, extraction procedures, protein expression and many other applications. They are spacious chambers in a footprint designed for the benchtop.

MaxQ 4000 benchtop orbital shakers are durable and easy to use with a spacious 18 × 18in. 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 0.75in. (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

Analog Models

• 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.

Digital Models

• 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
