Lab shakers are available in two different mixing actions: orbital and reciprocal and are primarily used for culturing organisms in shake flasks or test tubes, and can also be used for mixing liquids. Shakers range from small to mid-size bench top models, larger-capacity console (floor standing) models, or space-saving stackable models.
Top 5 Questions You Should Ask When Buying a 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. What are the temperature and humidity operating conditions for the unit?
5. What programming functions, if any, does the unit have?
Choosing a shaker comes down to such features as heating/cooling capability, capacity, shaking speed, orbital vs. reciprocating motion, ease of use, programmability, heating capability, and footprint. With research budgets tight and lab space even tighter, groups or departments are increasingly sharing shakers.
