OHAUS rocking and 3D shakers
The OHAUS rocking and 3D models are versatile shaking platforms for demanding laboratory applications. Thanks to their precise adjustment options, they are suitable for sensitive samples where conventional devices often reach their limits. Gentle, uniform shaking enables both gentle and reproducible results, which is essential in areas such as blood sample preparation or DNA analysis. A decisive advantage over comparable devices is the intelligent electronic control, which allows the angle and speed to be adjusted during operation. This saves users time and work steps and always achieves reliable and consistent shaking performance.
Efficient shaking technologies for numerous laboratory applications
These shakers are designed for a wide range of analysis and protocol requirements. They can be operated as rocking shakers (controlled tilting motion) or in the 3D version (low-foaming wave motion). Both in microprocessor-controlled digital versions and in cost-effective analogue versions, they allow laboratory personnel to adapt flexibly to any test situation. The non-slip coating material on the tray ensures that sample vessels remain stable in place while the shaker is working. The splash-proof design is particularly advantageous for experiments involving liquids or sensitive substances.
The most important technical features at a glance:
- Inclination angle from 0° to max. 20° (depending on model) for optimum mixing
- Speed ranges from 1 rpm to 75 rpm, depending on the variant
- Load capacities of up to 7.3 kg to process sufficient sample vessels simultaneously
- Microprocessor or analogue control for different accuracy requirements
- Robust die-cast aluminium housing with sturdy, non-slip tray
- Wide timer scale from a few seconds to over 100 hours
- CE and TÜV approval for high safety standards
Most models are equipped with stackable trays. This allows samples to be placed on several levels without taking up additional space in the laboratory. A high-quality stepper motor is used for all variations. This in turn ensures uniform acceleration from zero to set speed, minimising splashing as far as possible. The robust devices are also designed for a wide temperature range (-10 °C to 60 °C), which means they can also be used in air-conditioned areas or cold rooms.
Even with demanding tasks, such as colouring and decolouring gels or blotting techniques, the sophisticated concept is evident. The digital model variant allows the speed and time to be programmed so that even complex work processes can be automated. The analogue versions offer simple control via rotary knobs. This can be particularly worthwhile in areas with less frequently changing parameters, as operation is intuitive and quick.
Certifications and standards
All shakers have CE and TÜV certifications. This means that they comply with the current safety and quality standards for laboratory equipment in Europe. Both the housing and all relevant components are designed to withstand the stresses of continuous use. Approval by independent test centres underlines the reliability and high quality standards of these devices.
Application examples
- Mixing blood samples: Sensitive test series can be optimally homogenised thanks to the gentle but more constant movement.
- DNA extractions: Consistent shaking sequences are crucial to support efficient lysis of cells without damaging the DNA.
- Staining and destaining processes for gels: Gentle motion control prevents bubble formation and ensures better colour uptake.
- Blotting techniques in molecular biology: For Western, Northern or Southern blots, a uniform shaking rhythm prepares the sample material ideally for the reagents.
In addition, these devices are used in many other laboratory areas, for example in the investigation of bacterial cultures, yeast fermentations or hybridisation experiments in molecular biology research.
FAQs
How to adjust the speed
Through an intuitive user interface: for digital models, this is done using a touchpad in 1 rpm increments, for analogue models via a rotary knob with a scale.
Can the tilt angle be changed during operation?
Yes, the electronic control makes it possible to change the angle even during shaking without having to stop the device.
What warning functions are integrated?
The digital versions have visual and audible alarms in the event of overload. The analogue devices give an acoustic warning if an overload occurs.
Is the device designed for splash water and possible drops of liquid?
The housing is splash-proof. The non-slip mat is easy to clean, so dripping liquids are generally not a problem.
How are reproducible results guaranteed?
The microprocessor control in digital models helps to set parameters precisely and repeat them if necessary. Analogue models also allow reliable settings via the scale, but less precisely in the smallest increments.
Conclusion
These shaking systems can be used to cover a wide range of laboratory requirements efficiently and precisely. The choice between rocking and 3D movement and between digital or analogue control makes the portfolio flexible and adaptable. Thanks to the robust design, careful safety functions and extensive speed and tilt range, both light and demanding applications can be realised. Added to this is intuitive handling, which reduces operating errors and makes everyday laboratory work easier. These shakers are therefore a reliable choice for users who place the highest demands on consistent quality, safety and repeatability.
