Hettich - Hettich Rotina 420 Centrifuge

Applications & Use Cases

• 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 Specifications

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.
