Swing-out rotor, 4 positions, for Sigma 2-7

Swing-out rotor, 4-place, for Sigma 2-7

The rotor presented here is specially designed for use in Sigma 2-7 series centrifuges and impresses with its flexible handling. Thanks to its robust construction and four sample positions, it guarantees uniform centrifugation, making it the preferred choice in demanding laboratory environments. Compared to conventional rotor types, it offers greater variability for different sample volumes and vessel types, thus meeting a wide range of requirements in research and diagnostics.

Performance features and technical details

For optimum laboratory performance, this rotor combines various well-designed features and enables safe and efficient centrifugation. The most important points can be summarised as follows:

- Maximum speed of up to 4000 min-¹ for fast and reliable separation processes
- Four holders that support round buckets (model 13299) or 6-fold carriers (model 13296)
- Suitable for 5 ml to 15 ml round-bottom tubes and medical tubes up to 110 mm in length
- Reducing insert for vessels with a diameter of 4.5-7 ml and a length of 90-105 mm
- Excellent compatibility with common laboratory requirements in clinical diagnostics and research
- Easy to maintain thanks to the absence of rotor pins that require lubrication
- Robustly constructed individual components for reliable long-term operation With these features, the rotor makes a significant contribution to increasing efficiency in the laboratory. Its manufacture under strict quality and safety guidelines ensures reliable results in every application. In addition, the well-thought-out design offers users intuitive handling, which saves time and resources, especially in busy everyday laboratory work.

Its stable and balanced construction minimises vibrations, which are particularly undesirable at higher speeds. This not only results in increased user safety, but also prevents possible damage to samples or the device.

Certifications and standards

The rotor is developed in close accordance with current standards and certifications. This ensures that the product complies with relevant standards and meets the highest quality requirements:

- CE marking for compliance with European safety and health requirements
- Manufactured in accordance with ISO quality management guidelines to ensure long-term reliable performance

These certifications enable specialist laboratories to ensure that the rotor meets all prescribed safety, health and quality requirements.

Application examples

This versatile rotor covers numerous fields of application that are important in both the medical and research sectors. Examples include:

1. Processing blood samples in clinical diagnostics, for example to obtain serum or plasma.
2. Centrifuging samples in molecular biology that are required for DNA or RNA extraction procedures.
3. Sedimentation in biochemistry, e.g. to separate certain proteins or enzymes.
4. Checking particle densities in quality control of industrial processes to ensure consistent product standards

In addition, it is also recommended for use in cell biology to separate cell fractions or subcellular components when gentle yet effective centrifugation is required. In combination with the appropriate adapters, the range of vessel sizes can be easily covered.

FAQs

How are different vessels securely fixed in the rotor?

The vessels are secured using appropriate round cups or 6-fold carriers that are precisely matched to the vessel dimensions. In addition, a reduction insert can be used to securely fix smaller vessels and prevent them from slipping during centrifugation.

Does the device require special maintenance?

Regular cleaning and inspection of the rotor holder is recommended to achieve optimal results in the long term. However, this model does not require any greasing of the rotor bolts.

What are the maximum capacities?

Thanks to the four slots and the use of 5-15 ml tubes (as well as medical tubes up to 110 mm in length), a large number of samples can be processed in parallel per centrifugation run. This saves time and increases productivity in the laboratory.

What other safety measures should be observed?

In addition to observing the permissible speed (4000 min-¹), it is essential to ensure that all vessels are correctly balanced. Furthermore, before each centrifugation process, it should be checked that all rotor holders and adapters are securely fastened.

Conclusion

Thanks to its sophisticated design and high flexibility, this rotor offers above-average performance in clinical, scientific and industrial environments. It impresses with its robust design, compatibility with different tube types and easy maintenance. With its CE and ISO-compliant manufacturing process, it reliably meets modern safety and quality requirements. This swing-out rotor is the ideal solution for laboratories looking for a reliable partner for a wide range of applications in their Sigma 2-7 series centrifuges.
