The temperature of sample is kept 4℃ at maximum speed of rotation for all rotors (when the ambient temperature is 25℃).
Bioshield rotor
AF-2730 and AF-5004CS rotors are certified as biohazard-proof with the CAMR standards.
Samples will not leak out from the rotor even if tubes break.
These rotors can be used for inspections of BSE, SARS and so on.
