Low-Speed Centrifuge: Classification, Applications and Advantages
A low-speed centrifuge is one of the most common laboratory instruments, widely used in clinical diagnostics, biological research, food testing and industrial quality control. With a typical speed range of 300–6,000 rpm, it provides gentle centrifugal force for routine separation tasks while protecting sensitive samples.
1. Centrifuge Classification by Speed
Low-speed centrifuge: 4,000–8,000 rpm, RCF 1,000–10,000 g, for coarse particle suspensions, blood samples and cell harvesting.
High-speed centrifuge: 10,000–25,000 rpm, up to 50,000 g, for emulsions and fine suspensions.
Ultracentrifuge: 50,000–150,000 rpm, ≥505,000 g, for ultra-fine particles, proteins and macromolecular colloids.
2. Typical Applications
Clinical labs: Blood separation (3,000 rpm, 10 min), urine centrifugation (1,800 rpm, 5 min).
Aesthetic medicine: PRP/PRF preparation (2,000–3,500 rpm).
Food safety: Pesticide residue testing (4,000 rpm, 5 min).
Biology: Cell culture supernatant separation and gentle cell pelleting.
3. Key Advantages
Gentle separation, low risk of sample damage.
Compact benchtop design, easy operation and low noise.
Lower cost and maintenance compared to high-speed models.
High reliability for daily routine work.
4. Basic Operation & Safety Tips
Keep sample balance within 0.2 g to avoid vibration and damage.
Fill centrifuge tubes to ≤80% of maximum volume.
Place the unit on a solid, level surface with proper ventilation.
