Hettich Rotina 420 Centrifuge

• Separation of biological samples such as blood, urine, and cell cultures in clinical laboratories.
• Processing of samples for DNA/RNA extraction and protein purification in biotechnology research.
• Preparation of pharmaceutical compounds and quality control testing in drug development.
• Separation of components in chemical and material science research.
• Concentration of microorganisms and other particulates in environmental analysis.

Typical capacity

For this class of equipment, units commonly accommodate up to 4 x 250 ml or 6 x 94 ml tubes, or various microplates and smaller tubes with appropriate rotors.

Power supply

Units of this type typically operate on a standard single-phase mains supply, commonly 230 V, 50 Hz in the UK.

Maximum RCF (Relative Centrifugal Force)

Benchtop centrifuges in this performance range commonly achieve RCFs exceeding 24,000 x g, depending on the rotor used.

Maximum speed

Typical maximum speeds for a unit of this calibre can range from 15,000 to 18,000 RPM.

Temperature control

While specific to the model variant, many high-performance benchtop centrifuges offer refrigeration, maintaining temperatures from -20°C to +40°C.

Footprint

Benchtop centrifuges designed for high volume, such as the Rotina 420, are compact for their capacity, typically requiring a bench space of around 50-60 cm in width and depth.

• What types of rotors are compatible with the Hettich Rotina 420?

  The Hettich Rotina 420 is typically compatible with a range of swing-out and fixed-angle rotors, allowing for diverse applications from high-volume processing to high-speed microtube separation. Buyers should confirm the specific rotors included or available with this unit.

• Is this unit suitable for continuous operation?

• What maintenance is typically required for a centrifuge of this type?

• Does this model typically include refrigeration?

• What safety features are commonly found on the Rotina 420?

Centrifuges are valued across laboratories and biotech facilities for reliable sample separation. Buyers typically prioritise rotor compatibility, temperature stability in refrigerated models, and ease of maintenance when purchasing used units. Industry sentiment reflects appreciation for durable construction and consistent performance. Key considerations include verifying motor condition, checking calibration history, and confirming availability of compatible rotors. Well-maintained examples offer strong value and longevity, though wear on seals and bearings warrants inspection. Speed range and capacity alignment with intended applications remains important for operational efficiency.
