Low speed centrifuges

Low speed and small portable centrifuges that do no have aerosol tight chambers may allow aerosols to escape. Use a safety bucket to prevent aerosols from escaping. All centrifuges that have manufacturers rotor derating systems including ultracentrifuges,high speed centrifuges (Sorval and equivalent instruments) and high speed benchtop(Eppendorf, IEC, Jouan and equivalent instruments) must have an up to date record of the total hours of usage (refer to centrifuge use logs). Microcentrifuges and other low speed centrifuges do not require use logs.
