Low-Speed Centrifuge
Low-speed centrifuges usually top out at 6,000 r/min and rely on swing-out rotors and buckets. The long sedimentation path gives a flat interface between layers, which suits large-volume ambient separation: serum and plasma separation, routine urine and body-fluid testing, cell and tissue washing, and supernatant handling. Their value lies not in speed but in throughput and stability — several litres of sample per run makes them the highest-volume equipment in hospital laboratories, blood centres, CDCs and biopharmaceutical production lines. The MRK low-speed series comes in benchtop and floor-standing forms: benchtop for everyday work on the lab bench, floor-standing for batch processing in blood centres and industry.

Low-Speed Centrifuge FAQ
Grouped by real-world use cases for low-speed centrifuges. See the full FAQ for more questions.
Selection is not about speed but about the centrifugal force (RCF) your sample requires. For cells, bacteria, protein precipitation and nucleic acid prep that need high g-force, choose a high-speed model; for routine clinical separation of serum, plasma and urine, or large-volume supernatant work, a low-speed model is enough. If the sample is temperature-sensitive, add refrigeration to the requirement.
MRK centrifuges span speeds from 3,000 to 21,000 r/min, with capacities from 0.2 ml to 6 × 2400 ml. Products split into low-speed and high-speed classes, each available in ambient or refrigerated form, giving four main series: high-speed, low-speed, high-speed refrigerated and low-speed refrigerated.
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.
The dividing line is bench space versus throughput per run. Benchtop models sit on the workbench, are ready to use at any time and occupy little space, handling routine small-to-medium volumes with capacities up to 4 × 750 ml. Floor-standing models stand on the floor and accept large-capacity rotors (up to 6 × 2400 ml), suited to batch work in blood centres, biologics production and industrial solid–liquid separation.
