The Lab Companion model SK-300, SK-600, and SK-71 Series benchtop digital dual-action shaker uses 120V at speeds between 10 to 300rpm, and has programmable shaking motion, a selectable orbit diameter and stroke length, LED screens, and a direct drive, brushless DC electric motor. This shaker has programmable shaking motion with a timer, forward and backward motion, and pause between 10 seconds to 59 minutes 59 seconds. The orbital motion provides uniform mixing with a smooth continuous circular action. Reciprocating action provides a gentle to vigorous back and forth motion. A selectable orbit diameter and reciprocal stroke length ensures even mixing. The unit has timed shaking from one minute to 99 hours, 59 minutes, 59 seconds. Three LED screens show mode, time, and speed for clear readings. Laboratory shakers are used in many analytic procedures, including drug analysis, water pollution analysis, and hemolysis.

A direct drive, brushless DC electric motor provides smooth, quiet, uniform, and powerful shaking motion for high-speed applications and heavy workloads. Special acceleration and deceleration circuitry stops the shaking table at the same position allowing for automated dosing or sampling, and provides smooth start and smooth stop, preventing chemical spills from flasks or test tubes. This shaker is compatible with a choice of platforms, racks, and microplate holders (sold separately) that come in different sizes, handle capacities up to 4x6L flasks, and come with pre-installed clamps (dedicated platform) or without (universal platform). The low-profile design minimizes vibration or sliding caused by high-speed shaking motion. The casing is chemical-resistant for long life.

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.
