Introduction
A refrigerated centrifuge is a laboratory centrifuge equipped with a refrigeration system that cools the rotor chamber, maintaining the samples at a controlled low temperature during centrifugation, and it is used for the separation of biological samples, such as cells, proteins, nucleic acids, and subcellular components, which may be heat-sensitive and require low temperatures to preserve their integrity. In operation, the samples in tubes are placed in the rotor, which is placed in the refrigerated chamber, and the rotor spins at high speed, generating centrifugal force that separates the components of the sample by density; the refrigeration system cools the chamber, typically down to about -20 degrees Celsius or lower in some models, preventing the samples from overheating during the run and preserving temperature-sensitive samples, and the centrifuge provides precise control of the speed, time, and temperature, and it is available with various rotors for different tube sizes and capacities, and with different maximum speeds, from low-speed models for cells to high-speed models for subcellular particles. Refrigerated centrifuges are used in molecular biology for pelleting cells and bacteria, for isolating nucleic acids and proteins, for separating blood components, for preparing samples for analysis, in clinical laboratories, in biotechnology, in pharmaceutical research, and in many other applications, and they are available in various sizes, from benchtop models to large floor-standing units, with features such as temperature control, programmable runs, and safety interlocks. With their temperature control, refrigerated centrifuges are essential for the centrifugation of sensitive biological samples.

FAQ
Q1: What testing scenarios is this centrifuge mainly applied to?
A: The refrigerated centrifuge is used in molecular biology, clinical laboratories, pharmaceutical research, food testing, biotechnology and research to perform temperature-controlled centrifugation of samples for separation of cells, proteins, nucleic acids, organelles and other biological materials while maintaining low sample temperature to preserve sample integrity. It supports cell pelleting and separation, protein precipitation and purification, nucleic acid extraction, blood component separation, subcellular organelle isolation, and general laboratory centrifugation of temperature-sensitive samples. The refrigeration prevents sample degradation from heat generated during high-speed centrifugation, critical for biological and enzymatic samples.
Q2: What standards does the centrifuge comply with?
A: The refrigerated centrifuge complies with relevant IEC 61010 laboratory electrical safety standards, IEC 61326 for electromagnetic compatibility, applicable GB/T standards for centrifuges, and relevant safety standards for rotor integrity. The instrument follows applicable noise standards. Rotors should be certified for the maximum speed and load. Users should verify compliance with specific facility requirements for their application.
Q3: What is the warranty period for the whole machine and key components?
A: The whole refrigerated centrifuge is covered by a 12-month warranty. The motor, refrigeration system, controller, chamber and housing are covered, while rotors, adapters, gaskets and fuses are accessories or consumables. Rotor warranty may have specific terms. Damage from improper use, rotor overload or unauthorized repair is excluded. Extended service contracts are available.
Q4: Is this device difficult to operate? Is professional training required?
A: Operation requires basic training in centrifuge use, rotor selection and safety. We provide an operation manual and remote guidance. Proper rotor selection, sample balancing, speed/temperature setting, lid safety and maintenance are important for safe, effective centrifugation. Imbalanced loads can cause serious damage and injury.
Q5: What is the typical lead-time for order delivery?
A: Standard models require 7-30 working days. In-stock units can ship within 3-7 working days. Custom configurations or large built-to-order systems may require additional time, and we confirm the exact schedule before order confirmation.
Q6: Is regular calibration required? What is the recommended calibration cycle?
A: Speed calibration recommended every 6-12 months for critical applications. Temperature calibration against a reference periodically. Rotor inspection for wear and corrosion per manufacturer schedule. Routine cleaning of chamber and rotor. Refrigeration system performance verified. Full system maintenance annually.
Q7: Are supporting consumables universal?
A: Tubes, adapters, rotors and gaskets are available from laboratory suppliers, though rotor and adapter compatibility should be verified. Long-term consumable cost depends on tube usage and rotor choices.
Q8: Can I customize parameters or supporting accessories?
A: Customization includes maximum speed, capacity, rotor types (fixed-angle, swinging bucket, microplate), temperature range, control features and accessories. Additional rotors, adapters and tubes can be ordered separately. Custom orders extend delivery lead-time.
Q9: Does the purchase include on-site installation and commissioning service?
A: Standard delivery includes the refrigerated centrifuge and accessories with an operation manual. On-site installation, calibration and training are not included for standard orders but can be arranged for laboratory setup. Remote guidance is provided.
Q10: What types of samples are compatible with this equipment?
A: The refrigerated centrifuge separates liquid samples in compatible tubes, bottles or microplates within the rotor capacity, speed range and temperature specification. Different rotors are suitable for different sample volumes and types (microtubes for molecular biology, bottles for cell culture, microplates for high-throughput). Samples should be properly balanced across the rotor. Corrosive samples may require special tubes or rotors. Users should select appropriate rotor and tubes for the sample volume and speed, balance samples carefully (within rotor tolerance), set appropriate speed and temperature, ensure proper tube sealing to prevent leakage, follow proper biosafety procedures for pathogenic samples, and not exceed rotor maximum speed or load rating. The centrifuge should be placed on a stable, level surface. The chamber should be cleaned regularly, especially after sample spills. Rotors should be inspected for corrosion and cracks, and retired per manufacturer schedule. The refrigeration system should be maintained per manufacturer schedule. For clinical use, proper decontamination should be performed after centrifuging infectious samples. The lid safety interlock should never be bypassed.
