Shaking Incubators

Shaking Incubators

Shaking incubators combine precise temperature control with defined shaking motion for the cultivation of microorganisms, cells, and expression systems in Erlenmeyer flasks, culture tubes, and microtiter plates. The range includes configurable floor-standing units (Axotron, Zefa, Infors Multitron) as well as compact benchtop models with and without cooling—for laboratory requirements ranging from single units to stackable multi-tier solutions.

Shaking Incubators: Designs, Features, and Applications

Shaking incubators generate a uniform fluid flow in the culture vessel through orbital or linear shaking motion, which maximises oxygen transfer into the culture medium and balances concentration gradients. Temperature, rotation speed, and stroke are the primary process parameters; depending on the application, cooling, CO₂ gassing, humidity control, and growth lighting are added as further control variables.

Floor-standing units

Floor-standing shaking incubators offer large usable volumes for the simultaneous operation of many culture vessels and are often stackable or modularly expandable. The range includes the Axotron shaking incubator with magnetic drive and adjustable orbit (standard with cooling and 10" touchscreen), the Zefa shaking incubator with circular shaking stroke, and the Infors Multitron—all configurable according to individual requirements.

Benchtop units

Compact benchtop units for limited space or as a supplement to floor-standing units: the Axotron IS-RDD3 with cooling (shaking area 450×400 mm, Ø 26 mm orbit, 30–400 rpm) as well as several models without cooling (Axotron IS-RSD3, IS-RSDA, Labwit 311 DS, Infors Minitron) for different capacity levels and shaking strokes.

Vessel compatibility and accessories

All units are designed for operation with Erlenmeyer flasks, culture tubes, and microtiter plates. Depending on the model, vessels are secured via stainless steel spring clamps, plastic clamps, adhesive mats, or tension spring trays. Optional equipment includes CO₂ gassing, humidity control, and growth lighting for demanding cell culture applications.

 

Frequently Asked Questions About Shaking Incubators

Choosing a shaking incubator is not just a matter of temperature range or chamber size. Vessel sizes, culture capacity, shaking orbit and temperature requirements all need to work together. Here are some of the questions that frequently come up when selecting a system.

What should I look for when choosing a shaking incubator?

Start with your application. Which vessels do you use, how many need to be shaken at the same time, and at what temperatures and speeds? These requirements determine the platform size, shaking orbit, cooling and accessories you need. It therefore makes sense to compare complete configurations rather than just technical specifications and the basic price of the incubator.

Which shaking incubator is right for my application?

Tell us your application, vessel sizes, required capacity, temperature range and shaking speed. This usually narrows down the choice considerably. A compact benchtop unit may be the most practical solution for smaller batches, while floor-standing or stackable systems are better suited to higher capacities. We can help you determine which configuration you actually need.

When do I need a refrigerated shaking incubator?

If you need to work close to or below room temperature, active cooling should be considered. Keep in mind that the shaking process itself generates heat. For applications that operate exclusively well above ambient temperature, a non-refrigerated incubator may be sufficient. The best choice therefore depends on the actual temperature range of your process.

Which shaking orbit is right for my application?

A larger orbit is not automatically better. Orbit, shaking speed, vessel size and filling volume work together and influence mixing and oxygen transfer within the culture. Our range includes incubators with different shaking orbits as well as models with an adjustable orbit. The vessels you actually use should therefore be taken into account when selecting the system.

How many Erlenmeyer flasks can I fit into a shaking incubator?

The chamber volume alone does not provide a useful answer. What matters is the available platform area, flask size and the type of clamps or holders used. Tell us, for example, whether you need to shake 250 ml, 500 ml or 2,000 ml Erlenmeyer flasks and how many you want to use at the same time. We can then check which incubator, platform and clamp configuration provides the required capacity.

Which holders do I need for flasks, tubes or microplates?

That depends on the vessels you actually use. Different clamps, platforms and holding systems are available depending on the incubator. If you regularly work with different vessel sizes, a more flexible platform solution may be useful. It is therefore worth planning the accessories together with the incubator so that you know the actual usable capacity before ordering.

Why do shaking incubator prices vary so much?

Two incubators of a similar size are not necessarily comparable. Temperature range, cooling, shaking mechanism, usable platform area and equipment can differ considerably. Platforms, clamps and other accessories may also need to be added to the basic unit. When comparing quotations, check what is actually included and what your application requires. We can put together a complete configuration so that the incubator and accessories are matched to each other.
