OHAUS high-performance pre-mixer

OHAUS high-performance vortex mixer

This mixer is a professional solution for the powerful and uniform mixing of laboratory samples. It is particularly suitable for molecular biologists, biotech specialists and laboratory staff who require reproducible results in sensitive applications such as ELISA assays, PCR preparations or cell disruption. Thanks to its robust design and high-quality motor, the device enables constant performance across the entire speed range. Compared to conventional mixers, this series offers increased user-friendliness and higher load capacity - ideal for demanding continuous use.

Performance features and functionality

The series includes digital and analogue models. Both versions have an orbit of 4.9 mm, ensuring that samples are thoroughly mixed. A solid Cycoloy housing construction ensures maximum stability, while a powerful, German-made motor enables continuous high performance across the entire frequency range without any problems. Thanks to a maximum capacity of 1.1 kg, even heavy sample vessels can be processed safely. The speed control has been optimised for applications ranging from light shaking to intensive vortex mixing. This makes the device particularly versatile for complex laboratory tasks.

Key technical data

- Speed range: 300-2500 rpm (on mode), 300-3500 rpm (touch mode)
- Load capacity up to 1.1 kg for larger or multiple samples
- Orbit of 4.9 mm for efficient mixing
- Digital model (VXHDDG) with precise speed and time control
- Analogue model (VXHDAL) for flexible and cost-effective speed control
- Safety: CE and TÜV certified
- Dimensions (L×H×W): 24.1 × 16 × 16.8 cm

The digital mixer (VXHDDG) has LED displays that show speed and time simultaneously. This makes it easier to monitor parameters in repeatable tests and experiments. An integrated timer (1 second to 9999 minutes) allows runs to be precisely controlled. Especially in laboratories with a high volume of samples or in diagnostic facilities, these precise setting options contribute to a significant increase in productivity.

The analogue model (VXHDAL) is suitable if flexible mixing without extensive time control is required. It is controlled using user-friendly rotary controls. With its robust housing, powerful motor and variable settings, it is also designed for continuous operation. A three-stage switch (tap/standby/on) increases practical operability.Both models can be used via touch function or in continuous operation. The vortex movement ensures even mixing of all samples - from microtubes (0.5 ml) to 50 ml sample containers. Thanks to the universal holder and the spring-loaded attachments, various tube sizes can be conveniently fixed in place.

Certifications and standards

The device is fully CE and TÜV certified and fulfils high safety standards. Users benefit from reliable operation that fulfils both the requirements of modern laboratories and current standards. Thanks to its temperature-resistant design (4 °C to 40 °C), the device can be used in cold rooms or air-conditioned laboratories without compromising on performance.

Application examples

- ELISA assays: Fast and reliable mixing for breaking down antibody reagents
- PCR preparations: Uniform mixing of DNA, primers and enzymes in microtubes.
- Cell disruption: Ideal for homogenising cell lysates for further analyses.
- General protein samples: Thorough mixing of buffer solutions, concentrates or enzymes required for spectroscopic or chromatographic analyses.

FAQs

How can the speed be set precisely?

In the digital version, an LED display monitors the current setting. You can configure the speed and time precisely using buttons. The analogue model is controlled via a controller with a scale for approximate settings.

Can I process several sample sizes at the same time?

Yes, the universal holder and the optional foam inserts make it possible to mix different vessel types at the same time. In particular, 0.5 to 50 ml tubes can be securely attached.

Is continuous operation really possible

The high-quality motor and robust housing allow continuous operation, even at high speeds over long periods of time. Thanks to the intensive locking mechanism, the accessories remain firmly in place.

What do I need to bear in mind when cleaning?

The outer surfaces can be easily cleaned with a suitable cleaning agent for laboratory equipment. However, aggressive chemicals should be avoided so as not to damage the housing.

Which sample materials can be mixed

Enzymes, antibodies, buffer solutions or cell lysates are frequently used. In principle, the device is designed for a wide range of laboratory reagents as long as suitable vessels and attachments are selected.

Conclusion

Thanks to its powerful motor, high capacity and simple operation, the OHAUS high-performance Vortex mixer is an ideal choice for laboratories that require a flexible and efficient mixing system. The combination of precise digital control or versatile analogue control, as well as the additional touch mode, allows settings to be precisely matched to the process. Whether sensitive or intensive, this model handles a wide range of mixing requirements and helps laboratory professionals achieve reproducible results in the shortest possible time.
