These rotors are designed for use with the Hermle Z366 and Z366K (refrigerated) benchtop universal centrifuges and other models.
Each product page indicates the Max RPM and Max RCF achievable depending on the model.
As with all centrifuge rotors, buckets and adapter inserts may be required to complete the purchase or to expand the capabilities of a rotor without the additional expense of purchasing a new rotor.
