The Hermle 4 x 85ml rotor is a centrifuge rotor compatible with Hermle Z32-HK, Z36-HK, and Z446 series centrifuges. This rotor has a maximum speed of 15,000 RPM, which can be increased to 20,000 RPM with the Z36-HK centrifuge model only. It can generate a maximum relative centrifugal force (RCF) of 23,140 x g, or 41,137 x g with the Z36-HK centrifuge model. The rotor has a maximum capacity of 4 x 85ml and a maximum radius of 9.2 cm. The rotor is designed with a 30 ° angle that ensures the samples are centrifuged evenly. With its high speed and capacity, this rotor is suitable for a wide range of applications in research, clinical, and industrial settings.
