The Red Line range of centrifuges have sample volumes of 24 x 0.2 ml up to 6 x 1,000 ml. These centrifuges can be recognised by the red cover of the centrifuges as well the rotors which also have red covers. The table-top and floor standing centrifuges have an identical drive and mostly all of the rotors of the Red Line can fit in every centrifuge of the range. The models differ in the sizes of the chamber and the power of the machine. Therefore the maximum speed differs across the range.
