How Laboratory Shakers Are Being Used and What To Look For When Buying

Learn how often our readers use their shakers in their labs and more from our latest results

The wide variety of lab shaker designs on the market reflects the increasing diversity of scientific experimentation. Labs now use a greater range of sample sizes than ever before, from liters to microliters. And while replicate and combinatorial studies increase the number of samples, requirements for environmental control create yet a third dimension that shaker designers must consider.

Top 6 Questions You Should Ask When Buying a Laboratory Shaker

  1. What is the capacity of the unit (both for total weight and volume)
  2. What accessories are available?
  3. What is the RPM range and what increments can it be controlled in?
  4. Do you require a temperature controlled shaker? Incubating or water-bath shaker? Cooling?
  5. What shaking method do you require? Orbital, vortex, or rocking?
  6. What programming functions, if any, does the unit have?
