Large Benchtop Incubated and Refrigerated Shakers

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. These shakers are durable and easy to use with a spacious 18 × 18 in. platform for higher vessel capacity. They can handle up to six 2L flasks. The clear, scratch-resistant lid allows unobstructed sample viewing without disturbing chamber temperature.

Applications

• Insect cell culture
• Extraction procedures
• General mixing
• Staining and destaining
• Hybridizations
• Solubility studies
• Plasmid production
• Bacterial suspensions
• Washing procedures
• Protein expression

Advantages

• 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 the complete range with ±0.1C accuracy at 37°C with PID temperature controller
• Over temperature safety feature with an independent thermostat provides additional backup by controlling heat if the main temperature controller fails

Analog Models:

• Speed control from 40 to 400rpm by a 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 the 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
• An unbalanced load sensor stops platform motion when excess vibration is detected and visual/audible alarms signal until the condition is corrected
• The soft-start feature eliminates sudden starts and stops, splashing of vessel contents or wetting of flask closure
• A solid-state DC brushless motor is maintenance free
