Save valuable lab space with Thermo Scientific MaxQ 8000 Incubated Stackable Shakers, designed to be stacked two to three high on the floor without sacrificing performance. These stackable shakers have the durability to run at top speed stacked three-high, contain a HEPA filter that ensures the air inside the chamber remains clean and reduces cross contamination, feature a slide out platform that provides convenient 100% sample access. The stacking kits are included with each unit at no additional cost. Features : Three times the capacity of a floor shaker in virtually the same footprintBuilt for both sensitive eukaryotic culture applications - with contamination-reducing HEPA filtration, coved corner design, single-piece chamber and tight temperature uniformity - and for demanding prokaryotic culture applicationsRugged construction, wide speed range and no limits on "hard shake" speed, even when stacked three-high Microprocessor Control/Monitoring System: Run and setpoints displayed simultaneously Tracks total accumulated time on motor and drive systemsAudible/visual over- and under temperature tracking alarms ensure product protectionSeparate adjustable over temperature safety alarm with independent probe provides additional backup on heated unitsAudible/visual, high/low rpm tracking alarms alert to speed deviationsAlarms can be silenced temporarily and ring back as a reminder of unresolved alarm conditionsRemote alarm contacts for convenient monitoring from another locationNonvolatile memory saves settings during a power outage and automatically restarts the unit after power is restoredRS-232 port is standard and permits computer interface and monitoring of time, temperature and speedControlled acceleration circuitry provides smooth start-up and stopping to eliminate splashing and wetting of flask closuresFunctions can be calibrated easily through the keypad and sealed control panel Control Panel: Backlit two-line, 40-character LCD alphanumeric display of actual (run) and setpoint parameters and alarm condition Icons/buttons allow easy programming of set parameters Time: Counts upward, showing total operating hours and minutes for the runSpeed: Displays the actual platform speed (rpm) and speed set pointsTemp C: Displays the actual temperature inside the chamber and temperature set points Mechanics: Heavy-duty, eccentric drive mechanism allows extended speed ranges from 25 to 400rpm 1rpm with minimal vibration, even when shakers are stacked three high Durable, dynamically balanced orbital shaker mechanism ensures optimum oxygenation and nutrient mixing, reduced cell clumping, and prevention of splashing and flask wetting Triple counterbalanced mechanism provides optimum handling of full or unbalanced loads, regardless of flask placementCool-running, brushless, 1/3hp DC motor ensures continuous maintenance-free operationForced laminar airflow through the HEPA filter provides excellent temperature uniformity, reduces risk of cross-contamination Includes: Stacking kit with each shaker. Requires: Dedicated or universal slide out shaker platform 29.5 18" (74.9 45.7cm), sold separately. Note: WILL NOT SHIP TO RESIDENTIAL ADDRESSES.
