SIGMA 3-30KHS heated bench centrifuge
The SIGMA 3-30KHS is specially designed for laboratories that require high performance and precise temperature control. Consistent and reliable separation performance is essential, especially in clinical facilities, research laboratories and medical diagnostics. This table-top refrigerated centrifuge offers an unusually high speed and a wide temperature range, making it a reliable choice for numerous separations. Compared to other devices on the market, it impresses in particular with its flexibility in terms of rotor options, programme settings and integrated safety features.
Universal performance and precise temperature control
This laboratory refrigerated centrifuge scores with fast acceleration and deceleration times, so that samples can be reliably separated within a short period of time, even at high speeds. To make it easy for users to operate, it features a clearly structured TFT display that shows all important parameters in real time. From blood banks to DNA research, the device configuration is designed for a wide range of protocols and allows for a broad spectrum of applications. Even samples with particularly sensitive or temperature-sensitive additives benefit from the integrated cooling and heating function.
The device places particular emphasis on sample and user safety. A fully monitored microprocessor controls all functions and automatically corrects deviations that may occur, for example, during speed ramp-up or temperature control. In addition, warnings are issued when the programmed rotor running cycles are reached, ensuring a long service life and operational safety.
Important technical highlights
The following seven key data points illustrate the performance range of this laboratory centrifuge and show why it is suitable for a wide range of investigations and sample preparations:
- Speed range from 100 to 30,000 min-¹ for maximum flexibility
- Integrated cooling and heating functions for precise temperature control
- Capacity of up to 6 × 85 ml for processing larger sample volumes
- Max. kinetic energy of 43,753 Nm for efficient separation performance
- Very quiet operation at around 59 dB(A) with certain rotors
- Programming capacity of up to 60 methods for individual processes
- Functional TFT display with plain text instructions for intuitive operation
In addition, up to ten configurable acceleration and deceleration curves, a possible start refusal in case of excessive actual temperature deviation, and the adjustable tolerance range ensure a high level of safety. A built-in timer with a time span of 10 seconds to 99 hours 59 minutes allows for both short concentration experiments and long-term runs. For added convenience, a visual standstill indicator and an acoustic signal are available during operation.
Another advantage is the wide range of rotor options. Angle rotors, swing-out rotors or PCR rotors are pre-programmed at the factory so that users can immediately select the appropriate parameters. Sample integrity is maintained, especially at high speeds, as the temperature is continuously monitored and maintained as required.
Certifications and standards
The device has been designed to meet the requirements of professional laboratories and complies with the relevant standards. Reliable radio interference suppression is ensured in accordance with EN 61326. In addition, the centrifuge meets all essential requirements of safety standards for laboratory equipment to guarantee safe and stable operation.
Application examples
- Clinical laboratories: Fast and precise separation of blood components or cell fractions
- Blood banks: Processing large quantities of blood products for further use
- DNA research: Isolation and purification of sensitive DNA samples, e.g. for genetic analysis
- Medical diagnostics: Separation of proteins, serum, plasma or other components for disease detection. Depending on requirements, different types of samples such as emulsions, gas mixtures or suspensions can be processed. The range of applications is wide, from plasma extraction to the preparation of PCR samples.
What temperature ranges can be set?
The integrated heating and cooling function enables precise control over a wide temperature range, flexibly adjustable in 1 °C increments. This allows samples to be cooled or heated for specific applications without having to resort to external cooling capacities.
Is commissioning complicated?
The device can be set up in just a few steps. After unpacking, the centrifuge is placed on a stable table surface and can be loaded directly with the required rotors. Thanks to intuitive menu navigation, setup for various applications is easy.
How is safety ensured?
The microprocessor control monitors speed, temperature and running cycles. If there are any deviations or incorrect settings, the device displays warnings in plain text. In addition, a locking function prevents accidental changes to parameters during operation.
What needs to be considered when changing the rotor?
The permissible speeds are preset for each rotor. The user simply has to select the appropriate insert and check the rotor information in the user interface. The device automatically monitors whether all values are stored correctly and warns of any irregularities.
Conclusion
This all-rounder in the laboratory sector offers flexibility, high safety standards and precise temperature control. With its large capacity and a maximum speed of 30,000 rpm, the device can handle a wide range of requirements. Laboratories that require a constant working speed and accurate results when processing sensitive or extensive samples will particularly benefit from the combination of high operating comfort and solid technology. Thanks to its extensive range of rotors, highly efficient heating and cooling functions, and integrated monitoring systems, this benchtop refrigerated centrifuge is a powerful partner for demanding separation processes in clinics, research facilities, and diagnostic centres.
