Technical Data

Introduction about laboratory shaker

A laboratory shaker, whether a compact benchtop unit or a robust floor-standing system, is designed for the uniform agitation of liquid samples. By subjecting flasks, tubes, or plates to a defined rocking or circular motion, it achieves several critical goals: enhancing gas transfer (like oxygen into a culture), distributing nutrients or cells evenly, and promoting the dissolution of solids. This functionality is vital for ensuring that experimental conditions are uniform across all samples, which directly translates to the reliability of data in fields from molecular biology to analytical chemistry.

The device operates on the principle of controlled, repetitive motion to create fluid dynamics that mix contents. Orbital shakers, the most common type, create a gentle swirling action. For more vigorous mixing or specific protocols, linear shakers or even wrist-action shakers may be used. A significant advancement is the incubating shaker, which merges an environmental chamber with an agitation platform, enabling precise thermal control alongside mixing—essential for growing temperature-sensitive organisms or conducting enzymatic reactions.

Applications are deeply integrated into laboratory protocols. They are used for aerobic cell and tissue culture work, for blending reagents to create stable buffers, for eluting compounds from solid phases during extraction, and for ensuring even contact in staining and destaining gels. Modern features emphasize user control and convenience: LED digital displays show real-time parameters, programmable memory stores multiple protocols, and modular design allows for different platform attachments (e.g., for test tubes, microplates, or flasks) to accommodate diverse sample formats.
