Hettich Rotina 420 Centrifuge

• Separation of components in biological samples within clinical laboratories.
• Processing of cell cultures and purification of proteins in research settings.
• Preparation of samples for analytical testing in quality control laboratories.
• Concentration of precipitates and clarification of liquids in various scientific disciplines.

Typical capacity

Units of this class commonly accommodate up to 4 x 250 ml or a higher number of smaller tubes, often supporting microplates.

Power supply

Typically requires a standard laboratory power supply, commonly 230 V, 50/60 Hz for the UK market.

Maximum RCF (Relative Centrifugal Force)

For this model range, maximum RCF can typically exceed 24,000 x g, depending on the rotor fitted.

Temperature control

As a 'Rotina 420R' variant is mentioned, refrigerated models typically offer a temperature range from -20°C to +40°C.

Footprint

Benchtop centrifuges of this performance class are designed to be compact, typically requiring a bench space of around 50-60 cm in width and depth.

Rotor compatibility

Commonly compatible with a range of swing-out and fixed-angle rotors to suit diverse application needs.

• What types of rotors are typically available for the Hettich Rotina 420?

  The Hettich Rotina 420 series commonly supports a variety of swing-out rotors for high volume processing and fixed-angle rotors for higher RCF applications, accommodating different tube sizes and microplates.

• What are the benefits of a refrigerated centrifuge like the Rotina 420R?

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.
