Save valuable lab space with Thermo Scientific MaxQ 6000 Incubated/Refrigerated Stackable Shakers, which offer sample storage and orbital shaking with intuitive, easy-to-use digital controls. These shakers save space by stacking units two-high on the floor. Use the adapter set (available separately) to tier two 18 x 18" platforms to double shaking capacity. Features : Stackable units accept flasks up to 6L Two adjustable-height shelves provide added storage Choose from two temperature ranges to fulfill a variety of molecular biology, protein expression or plasmid purification studies Available in incubated or refrigerated modelsPrecisely monitor and control chamber temperature over complete range with 0.1 C accuracy at 37 C with PID temperature controllerOver temperature safety feature with independent thermostat provides additional backup by controlling heat if main temperature controller failsSolid-state DC brushless motor, variable speed control from 15 to 500rpmContinuous and timed operation from 0.1 hour up to 999 hours or 0.1 minute to 999 minutesView speed, operating time and temperature simultaneously on three individual LED displays, which help minimize errors in establishing running conditions Displayed time counts up during continuous operation and down during timed runsVisual/audible signals alert user to temperature deviations; heat turns off if temperature deviates 1 C of setpointShaker shutdown and audible/visual alarms signal if unit operates 10% of set speed, preventing the shaker from walkingEliminate sudden starts and stops with soft start featureUser-adjustable speed calibration can be performed using a digital handheld tachometer, where verification is required and protocols can be standardizedSafety interlock stops shaking motion when the door is openPlatform motion stops when excess vibration is detected due to an unbalanced loadRetains parameters during power failure and restarts unit automatically after power is restoredRS-232 interface allows remote monitoring of speed, time and temperatureLarge viewing window and internal light allow sample visibility, minimizing the need to open the door Door can be hinged from the right or left by the user for convenient placement in the lab18 18" platform can be dual-tiered inside the chamber to double the shaking capacityCorrosion-resistant stainless-steel chamber accommodates a variety of 18 18" (46 46cm) universal and dedicated platformsDurable powder-coated, cold-rolled steel exterior construction Electrical outlet inside chamber provides power for safe operation of shakers, stirrers or rotators Overall Dimensions: Platform dimensions: 18 18" (45.7 45.7cm) Overall dimensions L W H: 33 27 40.5" (83.9 69.6 102.9cm) Includes: Two adjustable-height perforated stainless-steel shelves. Required Accessories: Universal Platform (without clamps), or Dedicated Platform (with pre-installed clamps) Clamps Note: For a complete system, order platforms and clamps (sold separately).
