Hettich 20-place angle rotor for MIKRO 220 / 220 R
The Hettich 20-place angle rotor for MIKRO 220 / 220 R is the professional solution for high-performance centrifugation in medical, biotechnological and research-oriented laboratories. Specially developed as an accessory for the MIKRO 220 and MIKRO 220 R centrifuge models from Andreas Hettich, this rotor offers advanced functionality and efficiency. Thanks to its robust construction and optimised design, it guarantees reliable and reproducible results even under the most demanding conditions. Users benefit in particular from its precise balance, high capacity and intuitive handling, which make it the first choice over comparable rotor types. Performance features and technical highlights
The rotor impresses with its outstanding combination of safety, capacity and user-friendliness. Its technology has been specifically designed for processing small quantities and medium-sized batches with high sample throughput and is particularly suitable for demanding applications in routine clinical practice and molecular biology research.
Key technical data at a glance:
- Rotor type: Fixed angle rotor for high centrifugal forces
- Capacity: 20 sample tubes, suitable for standard tubes
- Maximum speed: Up to 15,000 rpm (depending on model and tubes, always follow the manufacturer's specifications)
- Maximum centrifugal acceleration: Up to approx. 21,379 x g
- Material: High-quality aluminium alloy, coated to be chemical and corrosion resistant
- Compatibility: Precisely fits MIKRO 220 and MIKRO 220 R centrifuges
- Temperature range: Can be used down to -2 °C (when used in the refrigerated centrifuge model MIKRO 220 R)
The patented geometric rotor design ensures even distribution of centrifugal forces, enabling very fast and gentle separation. The particularly large capacity and compact design significantly increase efficiency, especially when processing large numbers of samples. Thanks to the convenient release mechanism and safety lid with aerosol seal (depending on model), the rotor can be loaded easily and safely, while at the same time providing optimum protection against contamination and unwanted aerosol formation.
Special features:
- Reduced centrifugation times due to shorter sedimentation paths (compared to swing-out rotors)
- High sample capacity without loss of efficiency
- Compatibility with common sample vessels (e.g. EDTA tubes, PCR tubes)
- Durable construction - low maintenance requirements
Certifications and standards
The angle rotor complies with the relevant European safety standards (CE marking) and meets the relevant quality and safety standards, including the relevant sections of DIN EN ISO 61010. The material and manufacturing quality is ensured by strict internal controls at the manufacturer Andreas Hettich.
Practical applications
The sophisticated design of the angle rotor offers particular advantages in a wide range of applications - especially where speed and precision are decisive for the quality of the analysis.
Typical applications:
-
Blood group serology testing: Efficient and rapid centrifugation of anticoagulant tubes for blood group determination and cross-matching.
-
Serum and plasma collection: Ideal for the rapid and accurate separation of blood components for clinical chemical analysis.
-
Sedimentation under high gravitational fields: Processing of small cell or bacterial pellets in microbiology, ideal for high-gravity centrifugation up to approx. 21,000 x g.
-
Molecular biological analyses: Nucleic acid purification, e.g. DNA/RNA extraction from cell lysates, plasmid preparation.
-
Protein analysis: Concentration or fractionation of proteins from plasma and serum samples.
-
Urine analysis: Sediment formation for microscopic examination in urine diagnostics.
-
Immunohematology: Centrifugation of antiglobulin tests for the identification of immunohematological reactions.
Substances typically used in the above applications include EDTA or citrate blood, cell lysates, plasma samples, buffered saline and various stabilisers. The high resistance of the rotor material also allows the use of more aggressive laboratory reagents.
FAQs
What sample sizes are compatible with the rotor?
The rotor can hold up to 20 standard micro or blood collection tubes (e.g. 1.5/2.0 ml) and, depending on the adapter, smaller PCR tubes as well.
Is the rotor autoclavable?
Yes, the rotor and most inserts are autoclavable (12 °C, according to the manufacturer's specifications), enabling safe and effective decontamination.
Is there an aerosol seal?
For many centrifuge models, the rotor is available with a matching aerosol-tight lid that protects the user from infectious aerosols.
How does the rotor ensure maximum operational safety?
Precise workmanship, a robust locking mechanism and compliance with current safety standards (including CE, DIN EN ISO) ensure safe operation even at maximum speed.
What should be considered during cleaning and maintenance?
The rotor and inserts should be cleaned regularly with mild, laboratory-suitable cleaning agents and checked for damage. Please refer to the manufacturer's information.
