The Hengnuo 4-20R Refrigerated Centrifuge bridges the gap between high-speed performance and large-capacity flexibility. Reaching a maximum speed of 20,000rpm and 29,060xg RCF, it handles everything from micro-volume tubes (0.2ml) to 4x750ml swing-out rotors, all while maintaining precise temperature control from -20°C to 40°C.
Ideal for hospital labs, biopharma R&D, food safety testing, and university tenders, the 4-20R combines a patented NCP carbon fiber rotor (lightweight & corrosion-proof) with an intelligent touch screen and 10-grade acceleration control to protect even the most delicate samples.
