Orbital Shakers

Orbital shakers provide reliable motion control for culture flasks, microplates, and test tubes in microbiology, cell culture, and life science labs. Use benchtop orbital shakers for mixing, aerating, and incubating samples at precise speeds from 10-500 RPM. Available models include CO2-compatible all-environment shakers for mammalian cell work and compact units for limited bench space.

Frequently asked questions

What's the difference between orbital and reciprocal shakers?

Orbital shakers rotate in a circular motion, ideal for gentle mixing of culture flasks and microplates. Reciprocal shakers move side-to-side, better for test tubes and vigorously aerating cultures.

Can I use orbital shakers with CO2 incubators?

Yes. Models like the Benchmark ORBI-SHAKER CO2 maintain CO2 atmosphere while shaking, critical for mammalian cell and tissue culture requiring 5% CO2.

What RPM range do I need?

Standard aerobic cultures: 150-250 RPM. Mammalian cells: 100-150 RPM. Microbial cultures: up to 300-500 RPM.

What sizes do orbital shakers come in?

Platforms range from 7x8.5 inches (mini) to 18x30 inches (large). Medium platforms (13x12 inches) are the most common.
