Lab Shakers - Precision Movements and Repeatability Matter the Most
The breadth of this field reflects the wide range of applications. Shakers mix solutions for chemists, molecular biologists, physical scientists, and others. Many users, though, seek a particular style of shaking. “End users are reaching out for a very specific motion that they require for their applications,” says Nicole Kvasnicka, product marketing manager at Heidolph, headquartered in Schwabach, Germany. “They need to be very specific to not damage their samples.”
A range of specifications describes what a particular shaker does. Typically, a user looks for a shaker that provides a specific speed, often described in revolutions per minute (rpm), and one that carries a certain load, such as a number of flasks. For a shaker that moves items back and forth, the user might care about the stroke length—how far the carrying tray moves from left to right. Some users even want a shaker that goes from stop to stop in a specific amount of time.
