OHAUS multi-tube vortex mixer
The OHAUS multi-tube vortex mixer is a high-performance solution for anyone who needs to process large sample throughputs in the shortest possible time. Thanks to non-contact mixing technology, interchangeable foam racks and reliable speed control, demanding samples can be processed efficiently in areas such as clinical laboratories, genotyping or DNA/RNA tests. Compared to other devices on the market, the model is particularly impressive due to its stable operation, its flexibility with different tube diameters and its optional programming functions, which ensure repeatable and precise results.
Performance features and design benefits
This versatile laboratory device is specially designed for high load capacity and continuous operation. Its robust housing - either made from easy-care stainless steel, which is ideal for cleanrooms, or alternatively from painted steel - ensures a long service life as well as pleasant handling. At the same time, the ingenious vibration damping system prevents slipping: suction feet hold the blender securely in place even at high speeds.
An overview of the key technical data:
- Analogue (VXMTALB, VXMTAL) or digital (VXMTDGB, VXMTDG) version selectable
- Speed range (digital): 500 rpm to 2500 rpm; (analogue): 1200 rpm to 2400 rpm
- Orbit: 3.6 mm
- Maximum capacity: 4.5 kg
- Timer (digital): 1 second to 9999 minutes
- Mains connection: 230 V, 1 A, 50/60 Hz with 100 W power consumption
- Safety certificates: CE and TÜV
In addition, the device comes with a stainless steel foam rack that can hold up to 50 sample tubes. If required, six different foam racks can be used depending on the tube diameter (from 10 to 29 mm). The synthetic padding ensures that the samples are held securely, guaranteeing a uniform mixing result. With its compact format of around 241 x 406 x 384 mm and a weight from around 18.7 kg, the mixer can process a considerable number of samples simultaneously, but can still be easily integrated into existing laboratory systems.
The digital versions also have a programmable pulse mode, which can be used for particularly unruly media or stuck cell structures. Users can individually define the change between normal and intensive mixing intervals. Thanks to the separate LED displays for speed and time, all settings are always in view without the need for readjustment during work. For users who rarely need fixed settings, the analogue versions are a cost-effective alternative.
The solid construction, integrated vibration damping and wide operating range (operating temperature from 4 °C to 40 °C at 20 % to 85 % relative humidity) make the mixer a reliable partner in everyday laboratory work. With CE and TÜV certification, it fulfils relevant safety standards, which further benefits its suitability for use in various laboratory environments.Concrete areas of application and examples
Numerous applications in biochemical and clinical laboratories benefit from the high throughput made possible by this laboratory mixer. Typical examples include:
- Homogenisation of suspensions in bacterial cultures
- Preparation of genotyping samples
- DNA and RNA tests in clinical facilities or research laboratories
- Cell disruption or cell lysis prior to downstream analytical processes
Even sensitive substances such as RNA1 or highly concentrated protein concentrates are prepared reproducibly and without interference thanks to uniform mixing

FAQs
How does the non-contact vortex technology work?
This is a rotating shaking movement with a 3.6 mm orbit. The vibration means that the tube does not stick to the mixing attachment, but is held in place by the suction feet on the appliance and the secure hold in the foam frame.
Can I also use large tube diameters?
Yes, interchangeable foam racks cover a clamping range from 10 to 29 mm. This means that numerous tube formats can be used.
What is the difference between the analogue and digital versions?
Digital models allow the speed to be set precisely and offer a programmable timer as well as a pulse mode for more intensive mixing. Analogue versions, on the other hand, are simpler in design and less expensive to purchase.
How is the desired speed controlled?
In the analogue versions, the control is based on a rotary knob, while the digital models have buttons and an LED display. Both versions allow fine adjustment for consistent and reproducible results.
What safety features are available
The appliance is certified with CE and TÜV approval. In addition, strong suction feet, a robust steel or stainless steel construction and reliable foam frames ensure safe operation.
Summary
Thanks to its flexible handling, the choice between analogue and digital control, various foam racks and robust design, this vortex mixer is ideal for a wide range of laboratory scenarios. Whether routine clinical examinations, research work or industrial processes - the device fits seamlessly into numerous workflows and guarantees consistently precise results. If you are looking for a reliable, powerful and versatile mixing solution for samples with different volumes and requirements, this is the ideal laboratory aid.
