OHAUS vortex mixer

OHAUS vortex mixer

The OHAUS vortex mixer is ideal for mixing samples quickly and efficiently in laboratory environments. Users in chemical, biotechnological or pharmaceutical laboratories benefit from its user-friendly operation and wide range of setting options. Compared to other devices on the market, this model offers particularly high reliability and precision at variable or fixed speed - from gentle shaking to intensive high-speed mixing.

Powerful features for precise mixing results

The four different variants cover a wide range of mixing tasks. The digital model scores points with its precisely adjustable speed and timer function, while the analogue version is ideal for simple, manual adjustments. If a particularly high mixing speed is required at a low cost, the fixed speed version offers a constant output of up to 2800 rpm. The pulse model also reduces heat generation through intermittent operation and is ideal for sensitive samples or particularly efficient cell disruption. The robust design ensures a secure stand, even at high rotation speeds.

- Four model variants: Fixed speed, analogue, digital, pulse mode
- Speed ranges from 300 to 2800 rpm (depending on model)

- 4.9 mm orbit for most models, 2.5 mm for the pulse model
- Capacity of up to 0.5 kg per application
- Timer function (digital and pulse): 1 second to 9999 minutes
- Compact design with 21 x 16.5 x 12.3 cm (LxHxW)
- Operation at 4 °C to 40 °C and up to 85 % relative humidity

All models are CE and TÜV-certified, which ensures safe and standard-compliant use in laboratory environments. Thanks to the microtube holders and the 3-inch platform supplied, test tubes, beakers and flasks can be processed effortlessly. Users can also choose between the practical touch mode - for short, immediate activation by pressing - and continuous operation, which makes handling much easier.

The wide range of features also prove to be extremely convenient in everyday use. The digital version with microprocessor control keeps the set speed constant even with changing sample viscosities. The pulse model, on the other hand, scores with its uniform mixing results without unnecessary heat generation - perfect for samples that could quickly overheat with constant rotation. The analogue version and the fixed speed model meet the need for simple operation and high reliability - ideal for routine mixing or simple protocols.

Concrete application examples

- Homogenisation of cell cultures and suspension solutions, for example when working with HeLa cells, E. coli or other microorganisms
. - Mixing reagents and buffers for ELISA assays, where precise preparation is crucial for reproducible results.
- Drug extractions in pharmacies or pharmaceutical laboratories where samples need to be mixed at high speed.
- Rapid emulsification and resuspension of substances in diagnostic laboratories, for example for biopsies or blood serum.

Frequently asked questions

How is the speed set?

In the analogue version, the setting is made using a rotary control. The digital model, on the other hand, allows you to set the speed and time precisely using a keypad, while the fixed speed version always runs at 2800 rpm.

Can the appliance be used in the cold room?

Thanks to the operating temperature range of 4 °C to 40 °C, the appliance can be used in cooled rooms or refrigerated incubators as long as the humidity remains below 85 % and non-condensing.

What is the advantage of pulse mode?

In pulse mode, the mixing intensity is interrupted regularly, which reduces heat generation and is particularly beneficial for temperature-sensitive samples or for effective cell disruption.

Can I use different attachments?

Yes, all variants have a 3-inch platform included and additional holders if required. This means that beakers, flasks or several sample tubes can be used simultaneously.

Summary

The four model variants enable precise mixing at variable or constant speeds, suitable for a wide range of laboratory requirements. With their robust construction, high-quality workmanship and ergonomic design, they offer safety and durability in demanding research and development environments. At the same time, the CE and TÜV certifications guarantee compliance with important safety and quality standards. Complemented by the option of touch or continuous operation and different orbit sizes, these devices provide an optimal solution for anyone who needs reliable and versatile shaking in their everyday laboratory work.
