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 5 Questions You Should Ask When Buying a Laboratory Shaker
- What is the capacity of the unit (both for total weight and volume)
- What accessories are available?
- What is the RPM range and what increments can it be controlled in?
- What are the temperature and humidity operating conditions for the unit?
- What programming functions, if any, does the unit have?
