OHAUS digital standard orbital shaker Endeavor 5000 series

OHAUS Endeavor 5000 Series Digital Standard Orbital Shaker

This versatile orbital shaker excels in a wide range of laboratory applications, from microbiological cultures to sophisticated DNA studies. With its robust design and precise control, it is a reliable yet flexible choice for laboratories that require consistent shaking performance and reproducibility. Thanks to a powerful brushless DC motor and a wide range of accessories, the device offers an extremely wide range of applications compared to similar products on the market.

Equipment and mode of operation

The Endeavor 5000 series impresses with its high-quality workmanship and needs-based design for different sample volumes. The triple eccentric drive system ensures smooth motion sequences, while integrated overload and imbalance detection provides additional protection for sensitive samples. A compact footprint leaves more free space on the laboratory bench. The user-friendly operation is supported by an intelligent microprocessor control system, which ensures stable acceleration and thus effectively prevents splashes or foam.

Important technical data at a glance: - Three models with different orbits: 3 mm, 20 mm and a special version for microplates.
- Max. Sample load for standard models: 4.0 kg or up to 3 × 1-litre flasks each.
- Speed range depending on model: 50 to 300 rpm or up to 1200 rpm.
- Robust aluminium shell construction with attachment points for piston clamps and stirring racks.
- Operating environment: -10 °C to 40 °C, with up to 80 % relative humidity (non-condensing).
- Timer function from 1 minute to 99 hours, 59 minutes.
- RS232 interface for data logging and remote control.

In addition, a bright LCD display is integrated, making the speed and time clearly legible. If required, the timer can count up the elapsed time or count down to a preset value - in the latter case, the shaker switches off automatically as soon as the time has elapsed. Thanks to a visual and acoustic alarm function, users are also on the safe side, as they are notified in good time of error messages or timer expiry. The IP21 degree of protection also allows use in environments with increased humidity, for example in incubators or cold rooms, which further increases the flexibility of the orbital shaker.

Certifications and standards

The device fulfils important safety and quality standards, including CE and TÜV. These certifications signalise that all components meet the relevant requirements and that reliable operation is guaranteed. For laboratories that rely on standard-compliant documentation, this is a decisive quality feature.

Typical application examples

Orbital shakers are primarily used in the field of microbiology, where controlled mixing of bacterial or yeast cultures is essential. The following applications also benefit from stable and reproducible shaking:

- Cultivation of cell cultures (e.g. CHO cells) in Erlenmeyer flasks.
- ELISA and immunoassays where precise incubation is required
- Protein research, e.g. for staining or decolourisation processes.
- Viscosity and solubility tests in chemical laboratories.

Thanks to its programmability, multi-stage sequences for repetitive analyses or screenings can also be saved, which speeds up laboratory processes and increases the accuracy of the results.

FAQs

How to set the desired speed

The shaker is set using a digital control panel. A microprocessor regulates the acceleration so that the set speed is continuously maintained.

Can the device settings be documented or transferred to a PC?

Yes, via the integrated RS232 interface. This allows data to be sent directly to a computer and device-related parameters to be logged in real time.

Can the device be operated in a cold room?

The orbital shakers in this series are designed for a temperature range of -10 °C to 40 °C and are therefore perfect for use in incubators or cold rooms.

How is an exceeding of the maximum load recognised?

Internal overload and imbalance detection protects the drive. In the event of problems, both visual and audible warnings are given so that action can be taken in good time.

Which platforms or holding devices are included in the scope of delivery?

The scope of delivery includes a standard aluminium tray with attachment points and a non-slip rubber mat. Optional accessories such as universal platforms or specific piston clamps are also available.

Conclusion

The digital standard orbital shaker from the Endeavor 5000 series impresses in terms of performance, durability and user-friendliness. The variable use in different temperature ranges, the clear certifications and the extensive fields of application make it a sophisticated tool for every laboratory. Thanks to its compact design, easy access to samples and high shaking accuracy, the device proves to be the perfect solution for research and development in microbiology, cell biology, chemistry and beyond. If you are looking for reliable results and consistent long-term performance, this series is a sophisticated and durable system that is versatile and makes a significant contribution to optimising everyday laboratory work.
