High-Speed Refrigerated Centrifuge

Refrigerated high-speed centrifuges combine high-speed separation with active cooling and hold the set temperature throughout the run — the standard configuration for nucleic-acid and protein extraction, virus enrichment and inactivation, subcellular fractionation and cell-culture supernatant processing. The higher the speed and the longer the run, the more heat is generated; ambient models keep warming up in continuous operation, enough to compromise the activity of temperature-sensitive samples such as enzymes, antibodies and live cells. The MRK refrigerated high-speed series covers benchtop, micro, high-capacity and floor-standing forms, supports static pre-cooling and dynamic temperature control, and is selected by sample volume and required g-force.

High-Speed Refrigerated Centrifuge FAQ

Grouped by real-world use cases for refrigerated high-speed centrifuges. See the full FAQ for more questions.

MRK refrigerated centrifuges cover a temperature range of -20℃～+40℃, using an imported compressor unit with both static precooling and dynamic cooling to hold temperature throughout the run and protect temperature-sensitive samples.
Whenever the sample is temperature-sensitive: cells, enzymes, antibodies, nucleic acids, viruses and clinical chemistry items can lose activity or change results when the run warms up. Heat is generated at the rotor and tube walls, so ambient models are more prone to warming during long continuous runs. MRK refrigerated models hold −20 °C to +40 °C, with both static precooling and dynamic temperature control.
Rule out operational causes first: is the lid properly closed, is the chamber heavily frosted, is ambient temperature too high, are the vents blocked. If all that is in order and it still will not cool, the compressor may not be starting, refrigerant may have leaked, or the temperature probe may have failed — that needs service. Frequent lid opening also keeps the temperature from settling.
Mainly capacity and throughput, maximum g-force, the refrigeration system, rotor configuration, control and safety features (rotor recognition, imbalance detection, stored programmes), plus brand and service network. Cheaper models economise on rotor material, damping structure and compressor. Breaking the comparison down this way shows value for money better than comparing headline prices.
