OHAUS rocking and 3D shakers
OHAUS rocking and 3D shakers offer a versatile solution for controlled mixing in laboratories, research centers and medical facilities. Thanks to the uncomplicated adjustment of the tilt angle and speed, blood samples, DNA extractions or blotting techniques can be processed reliably and evenly. Compared to other laboratory shakers, they score points with their combined rocking or 3D shaft movement, a robust motor and user-friendly operation, which also allows adjustments to the angle of inclination and speed during operation.
Versatile features for laboratory use
This range of devices is characterized by its anatomical design and precise control technology. The models are available in both analog and digital versions, so that different reproducibility and budget requirements can be met. While the analog models have a cost-effective basic control with rotary knobs, the digital versions offer precise adjustment and display of speed, tilt angle and time. In addition, the integrated overload protection and automatic acceleration up to the set target value enable particularly safe and splash-free working.
Important technical data at a glance
- Movement types: Rocking movement with 0 to 15° tilt angle or 3D jogging up to 20° (depending on model)
- Maximum load: From 2.3 kg to 7.3 kg depending on the model
- Speed range: Infinitely variable from 1 rpm to a maximum of 75 rpm (depending on model)
- Bowl sizes: Vary between 32.4 x 25.4 cm and 35.6 x 27.9 cm
- Drive system: Durable stepper motor
- Control system: Analog or digital version, depending on the area of application
- Safety certifications: CE- and TÜV-approved for reliable operation
In addition, the shakers feature sturdy die-cast aluminum housings and non-slip mats for safe sample transport. The splash-proof design and a combined audible/visual alarm in the event of overload (or audible alarm for analog variants) ensure trouble-free operation in the laboratory. Most models are also available with stackable bowls, which effectively increases the mixing capacity.
Requirements and standards
All appliances comply with current safety and quality standards. The CE and TÜV marks confirm reliable compliance with machine guidelines and tested material safety. The laboratory shakers are also designed for different temperature and humidity ranges (-10 °C to 60 °C, 80% relative humidity).
Concrete application examples
- Mixing blood samples: Thanks to the gentle 3D movement, cells are not affected and blood components remain homogeneously distributed.
- DNA extractions: The controlled speed and adjustable tilt angles support sufficient resuspension and gentle mixing of sensitive molecular structures.
- Staining and destaining of gels: Gentle movements produce clean, uniform gel staining without excess foam formation.
- Hybridizations in molecular biology: Uniform, rocking shaking rhythms ensure the best possible attachment of labelled probes to DNA strands.
FAQs
How do I avoid foaming with sensitive samples?
Adjust the speed carefully and select the minimum angle of inclination required to achieve a gentle wave motion. Digital models allow very finely tuned settings here.
Can I leave the appliance running unattended for long periods of time?
Yes. Thanks to the splash-proof housing, overload protection and automatic acceleration, the shaker also works reliably over a longer period of time. A timer (depending on the model) also allows precise programming.
What maintenance measures are required
Clean the surface of the appliance and the non-slip mat regularly with a mild disinfectant. Also ensure a stable stand to compensate for vibrations and take the strain off the stepper motor.
Are the shakers available with interchangeable bowls?
Yes, almost all versions (except for some analog models) offer stackable or interchangeable bowls. This increases both capacity and flexibility when handling samples.
Conclusion
This shaker series impresses with its precise control, robust design and flexible application options. Different control concepts - from analog to digital - and a wide range of accessory options enable precise use for a wide variety of laboratory scenarios. Users benefit from gentle rocking or wave movements, a wide speed range and useful safety functions that ensure reliable continuous operation. Whether for blood samples, gel applications or complex DNA experiments: These laboratory devices cover a wide range of applications while remaining highly user-friendly and durable.
