Eppendorf M1352-0004 Excella E24R Benchtop Incubated and Refrigerated Orbital Shaker, 120V, 22" W x 30" D x 24" H, 4 x 2.8L Capacity

The Eppendorf M1352-0004 Excella E24R benchtop digital incubated and refrigerated orbital shaker uses 120V at speeds between 50 to 400rpm, and has continuous or timed shaking, an orbital motion range of 1.9cm/0.75", and a three-digit LED screen. This shaker is compatible with a choice of 46 x 46cm/18 x 18" (W x D) platforms (sold separately) that handle up to four, 2.8L Fernbach flasks and come with pre-installed clamps (dedicated platform) or without (universal platform). (W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) The shaker has continuous or timed shaking between 0.1 to 99.9 hours, after which the shaker automatically shuts off, while the temperature is maintained at its setpoint. The orbital motion provides uniform mixing with a smooth continuous circular action. A three-digit LED screen with keypad and indicator lights shows speed, temperature, time remaining, setpoints, and status. A proportional/integral (PI) microprocessor controls the speed, running time, and temperature over the entire range. Speed and temperature calibration can be accomplished directly using the keypad. The self-correcting microprocessor controller automatically compensates for changes in workload, voltage, and temperature to maintain operator-programmed setpoints. Laboratory shakers are used in many analytic procedures, including drug analysis, water pollution analysis, and hemolysis.The chamber is covered with a clear lid for unobstructed sample viewing without disturbing chamber temperature and holds flasks up to 2.8L. Visual and audible alarms alert to the end of a timed run, deviations from the speed setpoint (five minutes after the lid is closed), deviations from the temperature setpoint (five minutes after lid is closed), a power failure, and when the lid is open. A safety switch automatically stops the shaker mechanism when the lid is opened. An acceleration/deceleration circuit eliminates wetting of flask closures, which could interfere with oxygen transfer and also prevents sudden starts and stops. A powerful fan and heater provide rapid heat-up and temperature recovery after door opening. The unit has an RS-232 interface for logging data directly to a computer. This shaker conforms to the Underwriters Laboratories (UL), Canadian Standards Association (CSA), and European Conformity (CE) marking standards.SpecificationsSpeed range50 to 400rpmOrbit1.9cm/0.75"Temperature range15°C below ambient to 60°CTemperature uniformity+ or - 0.5 at 37°CTime setting range0.1 to 99.9 hoursCapacity4x2.8L flasksOperating temperature10 to 35˚COperating relative humidity20 to 80% noncondensingElectrical requirements120V, 60HzPlatform dimensions18 x 18 inches (W x D)Shaker dimensions24 x 22 x 30 inches (H x W x D)Weight80kg/175lb.H is height, the vertical distance from the lowest to highest point; W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.Laboratory shakers agitate liquids during laboratory procedures. These devices can be analog or digital and are typically an automated, electrically powered, countertop unit that shakes liquid in lab containers, such as flasks, funnels, or test tubes. Some shakers can operate inside fume hoods, incubators, refrigerators, or other laboratory devices, and can include controls for the frequency and/or degree of movement. The types of shakers include: orbital, rocking, rolling, rotating, and wrist action. The most common orbital shaker provides a smooth, continuous, circular motion, sometimes with a tilt angle, for uniform mixing of contents. The rocking shaker creates gentle uniform mixing with a see-saw, or up and down, motion. Reciprocating, or rolling, shakers provide a horizontal side-to-side motion with simple agitation of samples. A rotating, or rotisserie, shaker provides samples with a rotating action that moves in a circular motion. Wrist-action shakers duplicate the effect of hand mixing with "arms" on each side of the unit. Some shakers have the ability to incubate or refrigerate samples while providing shaking action.Eppendorf manufactures instruments for cell manipulation and automated devices for liquid handling, for use in life science research laboratories. The company, found in 1945, is headquartered in Hamburg, Germany.
