Orbital Shakers & Mixers
Orbital Shakers: Orbit, Speed and Platform Load
Laboratory shakers are distinguished by their motion, not their price. Circular orbital motion for cultures and general mixing, linear motion for blood tubes, 3D motion for gentle mixing, and rotators for continuous end-over-end mixing.

- 20 mm orbitthe standard for culture and mixing
- 0.8-5 kg loaddepending on platform size

Four types of motion and their uses
| Type | Motion | Best suited to |
|---|---|---|
| Orbital | horizontal circular, 20 mm orbit | microbial culture, dissolution, flask and plate mixing |
| Linear (reciprocating) | back and forth, 20 mm stroke | blood tube and clinical sample mixing |
| 3D oscillation | 10° tilt in three dimensions | gentle mixing, gel staining, fragile samples |
| Rotator | end-over-end rotation, 40-80° angle | centrifuge tubes, extraction, continuous incubation |
Figures to match before buying
- Maximum platform load. A 1 L Erlenmeyer full of media is far heavier than a microplate. A 2 kg unit and a 5 kg unit serve different needs.
- Platform area and clamps. Make sure the flask clamps or tube racks you use are available for that platform.
- Low-speed range. For sensitive cell culture, a 40 rpm lower limit matters more than a high top speed.
- Use inside an incubator or cold room. Not every shaker tolerates high humidity or low temperature; tell us the intended use so we pick a suitable model.
- Duty cycle. Overnight protocols need a motor rated for continuous operation together with a long timer.

Frequently asked questions
What does a 20 mm orbit mean on an orbital shaker?
The orbit is the diameter of the circle the platform travels each revolution. A small orbit (around 10 mm) gives gentle mixing suited to microplates; a 20 mm or larger orbit gives better aeration for flask cultures.
Orbital shaker or magnetic stirrer?
A magnetic stirrer agitates one vessel with a magnetic bar inside the liquid. An orbital shaker agitates many vessels at once with nothing entering the sample, which suits cultures and samples that must stay sterile. See magnetic stirrer options.
What load is safe for the platform?
Do not exceed the stated maximum load, and count the total weight including media, clamps and racks. Overloading destabilises the speed and shortens motor life.
Can these shakers run overnight?
Yes. The PRO series has a timer settable from 1 minute to 23 hours 59 minutes, so runs stop on schedule without supervision.
