Fixed-angle rotor 20 x 15 ml for Sigma 2-7
The fixed-angle rotor impresses in modern laboratory research and diagnostics with its high capacity and reliability. Developed and manufactured by Sigma Laboratory Centrifuges, it is specially designed to meet the requirements of demanding laboratories. This rotor allows larger sample volumes to be processed in the shortest possible time, which is a decisive advantage, particularly in areas such as molecular biology, clinical chemistry or haematology. Compared to similar products, this rotor stands out thanks to its combination of precision, user-friendliness and solid workmanship, which ensures maximum safety.
Design and technical features
High speeds during centrifugation generate high loads, which is why resistant materials and a well-thought-out design are essential. The rotor has several special features that make it robust and versatile at the same time:
- Maximum speed: 4000 min-¹
- Maximum relative centrifugal force (RCF): 2486 x g
- Capacity: 20 tubes with a volume of 15 ml each (round-bottom, Falcon or comparable medical tubes)
- Maximum tube length: 120 mm with a diameter of up to 17 mm
- Compatible with various adapters
- CE marking and manufactured in accordance with ISO standards
- Constructed from sturdy, chemically resistant materials
This means that blood collection tubes, culture tubes or sample vessels for microbiological testing can be used without any problems. The design takes everyday laboratory scenarios into account and guarantees safe handling even with repeated use.
In addition, the design enables balanced weight distribution, which is an important prerequisite for reliable measurement results. Thanks to its solid workmanship, the rotor also supports longer running times. This increases efficiency without compromising on quality.
Optimal customisation options
Several adapter options are available to meet different requirements. These allow vessels between 4.5 ml and 15 ml to be centrifuged reliably, ensuring maximum flexibility. Common adapters include:
- Adapters for 5 ml tubes with a diameter of 13.5 mm to 17 mm
- Adapters for 5 ml tubes with a diameter of 12.8 mm
- Adapters for other tubes between Ø 12.3 mm and Ø 17 mm
This makes it easy to adapt samples to different protocols. The rotor lid closes securely and holds the contents reliably in place even at maximum speed. This reduces the risk of premature damage and guarantees a long service life.
Examples of applications in everyday laboratory work
To illustrate the versatility of this rotor even more clearly, here are some specific examples:
- Blood diagnostics: Separation of blood samples, e.g. for the quantitative determination of serum, plasma or blood cells
- Microbiological investigations: clarification of bacterial suspensions, removal of cell debris or preparation of culture media
- Cell and tissue cultures: separation, washing and harvesting of cells as well as conditioning of culture supernatants
- Molecular analysis: Sample preparation for DNA and RNA isolation, protein extraction or enzyme tests. These areas often require high sample density, reproducible results and fast sample processing - a profile that the rotor reliably fulfils.
Certified and tested by laboratories
As safety and quality are paramount in laboratory processes, the rotor is manufactured in accordance with current guidelines and standards:
- CE marking: Compliance with European health and safety regulations
- ISO standards: Ensuring consistent quality and reliability
Compliance with these standards means that the rotor can be integrated into existing workflows with virtually no concerns. At the same time, laboratories benefit from maximum flexibility in handling and planning reliability for certification processes.
FAQs
