An orbital incubator shaker combines the features of a shaker and an incubator, hence eliminating the need to place a separate shaker inside of an incubator. Typical uses of shaking incubators are for bacterial cell culturing, cell aeration, tissue cultures, yeast growth and solubility studies.
The orbital shaking mechanism ensures that nutrients are evenly distributed within the culture media as well as assuring that adequate oxygen is dissolved into the media. Typically, the time and rotational speed of the orbital shaking mechanism are adjustable. The temperature within a thermo shaker incubator may be set to provide the ideal temperature for the media.
Features to investigate when purchasing a rotary shaker incubator include the settable temperature range, a programmable timer, adjustable rotational speed (RPM), temperature uniformity and an easy to clean interior.
Orbital shakers are available in a range of sizes that include upright and benchtop shakers. A wide range of temperature capabilities is available in order to meet the specific growth requirements of the media being incubated. There are refrigerated shakers that go down to as cold as +5°C for applications such as protein expression, to +22°C for blood platelet agitation, and up to +70°C for high temperature shakers that can be used for the growth of thermophiles organisms.
Which type of temperature control do I need?
Even if you currently only have the requirement for a heated incubated shaker, it may be worthwhile to consider if at some stage in the future you may need to incubate media at a lower temperature range.
Heated Incubator shakers
These are used for incubation where the required temperatures are at least 5°C above the ambient temperature of the room.
Heated & Refrigerated Incubator Shakers
Shakers with the capacity to both heat and cooling are required for applications where the required incubation temperature is less than 5°C above the room temperature.
