1 Any tube that fits in the rotor is okay for centrifuging. *
2 Rotors may require adapters depending on the type of centrifuge tube. *
3 Infectious and/or radioactive materials are allowed if the containers are tightly closed. *
4 It is ok to leave once the centrifuge starts and is safely up to speed *
5 Rotors do not need to be pre-cooled for sub-ambient centrifugation. *
6 The total weight of product, tubes, lids, etc does not matter, only RPM’s. *
7 The maximum rotor speed must be derated if the maximum load capacity is exceeded. *
8 Users that do not consistently and accurately record usage in log book will be banned from using the centrifuge. *
9 Rotors that are properly maintained will last forever. *
10 Rotors should never be submersed in water. *
11 If your method reports an ‘rpm’ without information on the type of rotor, you do not have all the information you need. *
12 If your method reports a ‘g’ force, you can use another rotor to achieve the same g force *
13 "Compartment mass" includes total contents of any compartment, including sample, tubes, adapters, etc. *
14 The total contents of any compartment, including specimen, tubes, sealing assembly and adapters must not exceed the specified maximum compartment mass unless rotor speed is reduced proportionately. *
