Laboratory shakers, ranging from space-saving benchtop units to high-capacity floor models, are engineered for consistent sample agitation. Their function is to mix, aerate, or suspend the contents of flasks, tubes, or plates through controlled mechanical motion. This action ensures the creation of homogeneous environments, which is a prerequisite for accuracy in applications like cell culture, protein studies, and diagnostic assay development.
The operational principle is based on imparting standardized kinetic energy to samples. This mechanizes a critical step that is difficult to control manually. The orbital shaker is the most common implementation. For protocols requiring environmental control, incubator shakers are employed. Modern versions are characterized by sophisticated user interfaces, often featuring color touchscreens, data logging capabilities, and programmable protocol sequences for complex, multi-day experiments.
Shakers are applied across diverse scientific activities. They are used for culturing insect cells for baculovirus expression systems. They assist in solubility and stability testing of new chemical entities. In clinical laboratories, they ensure consistent mixing of samples in blood culture bottles. Important design and performance features include a vibration-damped drive system for smooth operation, a range of available platform sizes and configurations, and safety interlocks to prevent operation when access doors are open.
