What is the primary benefit of a refrigerated centrifuge?

The primary benefit is the ability to maintain samples at a controlled low temperature, which is crucial for preserving the integrity of heat-sensitive biological materials during centrifugation.

Can different types of rotors be used with this model?

Many centrifuges, including the CR 4i, are designed to be compatible with a range of interchangeable rotors, such as swing-out and fixed-angle types, to accommodate various tube sizes and sample volumes. Buyers should confirm rotor availability with the seller.

What maintenance is typically required for a refrigerated centrifuge?

Routine maintenance commonly includes cleaning the rotor chamber, checking the refrigeration unit for proper function, and ensuring the rotor is balanced and free from damage. Regular calibration may also be required.

Is installation complex for this type of equipment?

Installation typically involves placing the unit on a stable, level bench and connecting it to a suitable power supply. No specialised plumbing is usually required, but ensuring adequate ventilation for the refrigeration system is important.

What safety features should I look for?

Key safety features commonly include rotor imbalance detection, lid interlocks to prevent operation while open, and overspeed protection. These features are standard on modern laboratory centrifuges.

Typical context for this category of equipment. Always confirm specifics with the seller.

Separation of biological samples in research laboratories.
Processing of blood components in clinical settings.
Cell culture harvesting and purification.
Preparation of samples for analytical testing.
Protein and nucleic acid isolation.

Typical capacity: For this class of refrigerated centrifuge, capacities commonly range from several hundred millilitres up to several litres, often accommodating various rotor types.
Power supply: Units of this type typically require a standard laboratory electrical supply, often 230V, 50Hz in the UK, though 120V, 60Hz units are also common, particularly for imported equipment.
Temperature control: Refrigerated centrifuges commonly offer a temperature range from approximately -10°C to +40°C to protect temperature-sensitive samples.
Maximum speed: Benchtop refrigerated centrifuges typically achieve speeds up to 10,000 rpm, depending on the rotor and application.
Footprint: These units are designed for benchtop use, with dimensions varying but generally requiring significant bench space due to their weight and size.
Rotor types: Units commonly support both swing-out and fixed-angle rotors, allowing for versatility in sample processing.

The primary benefit is the ability to maintain samples at a controlled low temperature, which is crucial for preserving the integrity of heat-sensitive biological materials during centrifugation.

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.
