OHAUS high-performance orbital shaker
The OHAUS high-performance orbital shaker is ideal for demanding laboratory applications such as cell cultures, extractions, bacterial and yeast cultures or solubilisation studies. The reliable system ensures a smooth and controlled shaking motion even with heavy loads, making it the first choice for laboratories looking for high precision, durability and scalability.
Versatile application options for optimal results
This powerful model covers a wide range of daily and specialised tasks in biotechnology, pharmaceutical and research laboratories. Different versions with analogue or digital controls enable individually tailored applications. Thanks to the high load range of up to 68 kg and precise speed control, samples are mixed reliably and reproducibly. The triple-eccentric design, together with the brushless DC motor, ensures smooth operation and low maintenance. The digital version includes an RS232 interface via which control and logging data can be easily exchanged.
In addition to the robust design made of cold-rolled steel, the device has special safety mechanisms, including slow acceleration to prevent splashes. A load sensor automatically adjusts the speed in the event of an imbalance, further increasing sample and user safety. The convenient timer and easily removable tray with non-slip rubber mat provide even more convenience. Certified according to CE and TÜV, the device fulfils common safety and quality standards.
Important technical features at a glance

In addition, all models are made of a sturdy steel construction and have a robust aluminium shell that minimises vibrations. Thanks to the precise speed calibration, the shaking movement remains consistent and reproducible - a decisive advantage for test series that run over longer periods of time. The low heat generation and effective cooling system also enable continuous runs without compromising on performance.
Application examples from everyday laboratory work
- Cell cultures: The uniform shaking motion promotes a homogeneous distribution of nutrients and ensures optimum growth conditions in cell culture flasks.
- Bacteria and yeast cultures: Continuous shaking improves oxygen supply and cell growth, which is particularly essential in microbiology.
- Extractions and solvent studies: Thanks to high capacities and precise speed controllers, complex substances such as proteins, enzymes or lipophilic active ingredients can be extracted effectively.
- Staining and destaining methods: All samples, from tissue sections to colonies on agar plates, benefit from the constant movement and even distribution of the colouring or destaining solutions.
- Immunoassays: Sensitive antibodies are often used to stabilise reagents and samples. The controlled shaking speed prevents deposits and damage.
Thanks to its robust design and the exclusive Accu-Drive shaking system in digital versions, the shaker is a reliable partner for demanding procedures in molecular biology (e.g. protein purification) and pharmaceutical research (e.g. drug screening tests).
FAQs
How can the speed be set precisely?
Digital models have LED displays and a precise speed setting. The set speed can be regularly checked and fine-tuned using the integrated calibration function.
Does the appliance require special maintenance?
The brushless DC motor runs virtually wear-free. An occasional visual inspection of all moving parts and gentle cleaning with a mild detergent are sufficient to maintain long-term functionality.
Are different jug sizes compatible?
Thanks to the locking mechanism for accessories, different racks, holders and clamps can be securely mounted. This means that different vessels can be used flexibly, from small tubes to the large Erlenmeyer flask series.
Can the shaker be used in cooling or heating chambers?
Depending on the model, it can be used in temperature ranges from 0 °C to 40 °C or even -10 °C to 60 °C. This means it can be operated safely in cooled or heated laboratories as long as the permissible humidity is not exceeded.
What happens in the event of an imbalance due to uneven loading
An in-built load sensor recognises imbalances and reduces the speed to a safe level. This prevents damage to the appliance as well as to samples.
Summary
These heavy-duty shakers offer a reliable blend of rapid mixing, constant speed and versatility for laboratories of all orientations. The robust design, low maintenance requirements and precise control make them a long-lasting, safe and economical investment. Whether for sensitive cell culture applications or intensive solvent studies - every user benefits from high flexibility and consistently reproducible results.
