SIGMA 3-18KHS heated benchtop refrigerated centrifuge

The SIGMA 3-18KHS heated benchtop refrigerated centrifuge is a versatile instrument with integrated heating and cooling functions, which is primarily used in clinical laboratories, blood banks, DNA research and medical diagnostics. Compared to competing devices on the market, it impresses with its robust design, flexible rotor options and user-friendly control system, which combines precise results with high safety standards.

Performance features and technical highlights

This high-quality universal centrifuge enables reliable separation processes for a wide range of sample volumes and substances. The integrated temperature management (from -10 °C to +40 °C) allows particularly temperature-sensitive samples to be processed gently. Below is a selection of the most important technical specifications:

- Speed range: 100 to 18,000 rpm for maximum flexibility
- Tube volumes from 0.2 ml to 400 ml - ideal for different analysis quantities
- Easy-to-read TFT display with permanent target and actual values
- Integrated heating and cooling function for precise temperature control
- Convenient 60 programmes for individual adaptation to different tasks
- Low noise level between 60 dB and 66 dB (depending on the rotor)
- Stable construction with a device weight of 78 kg without rotor

In addition, the control system supports multiple acceleration and braking curves (linear, quadratic and freely definable), allowing the centrifuge to be adapted to a wide range of requirements. A four-digit numerical code serves as an access lock and prevents unauthorised use. The automatic lid lock ensures safe and smooth operation.

Safety and intelligent features

The centrifuge has a modern microprocessor control system that ensures precise control of all processes. The device only starts when the set temperature is reached or is within a configurable tolerance. This prevents possible damage to temperature-sensitive samples and supports constant conditions.
Other features include a visual standstill indicator, automatic lid release at the end of the run (can be deactivated if desired) and warning messages when the rotor's permissible service life has been reached. The fast "Rapid_temp" programme is also integrated to quickly bring the interior to the desired temperature.

Certifications and standards

This benchtop refrigerated centrifuge complies with the requirements of EN 61326, ensuring reliable radio interference suppression in the laboratory environment. It also has additional safety features, such as start interruption if the actual temperature difference is too high. All relevant standards and certifications are met to ensure professional laboratory operation.

Application examples

The compact design and wide variety of rotors make this device an indispensable piece of equipment in many industries and specialist areas:
- Clinical laboratories: For separating blood components and other biological materials.
- Blood banks: For reliable processing of blood reserves and blood plasma.
- DNA research and molecular biology: For isolating and purifying DNA and RNA or for processing PCR approaches.
- Medical diagnostics: For gentle sample preparation that ensures accurate and reproducible test results.

In addition, thanks to the inertia effect, this centrifuge can also be used to separate emulsions or gas mixtures, which can be of great benefit in research and industrial environments.

FAQs

Which rotors can be used?

Angle and swing-out rotors, PCR rotors and special rotors, among others, are compatible. This allows flexible adaptation to different sample volumes and requirement profiles.

How is the temperature controlled?

An integrated heating and cooling function enables precise temperature control from -10 °C to +40 °C. In addition, the temperature can also be maintained at a standstill, which protects sensitive samples.

Is it complicated to operate?

Despite the extensive range of settings, the control system is extremely user-friendly. The TFT display provides clear text instructions, various curve programmes and intuitive menu navigation.

What special safety features are integrated?

In addition to the lid lock, the safety concept includes a start refusal function in the event of excessive temperature deviation, a visual standstill indicator, warnings about the end of the rotor's service life and a four-digit numerical code for authorised access.

Conclusion

The SIGMA 3-18KHS heated benchtop refrigerated centrifuge combines reliable cooling and heating performance with state-of-the-art control technology and high safety standards. It offers every laboratory an optimal solution for efficiently separating and processing blood samples, PCR preparations, emulsions and other sensitive substances. Its robust construction, wide temperature range and high user-friendliness ensure the best results in a wide variety of applications, making it extremely valuable in its field of use.
