A kit rotor from Eppendorf offers a solution for a common problem when working with MiniPrep spin column kits, used in purifying nucleic acids applications. These kits use filters that fit within microcentrifuge tubes, which commonly prevent the lid from closing. Centrifugation is required at high speeds during the elution step, where consequently the lids of the tubes shear off creating tiny projectiles within the rotor. This problem traditionally occurs because standard rotors do not provide enough support for open tube lids during centrifugation.
The Eppendorf Kit Rotor was designed with an extended rim that serves as support for the open tube lids, which prevents the lids from shearing off. In addition to the extended rim, this rotor also has been designed with the bore-holes further apart from each other than those on a standard microcentrifuge tube rotor. This offers the user peace of mind and convenient handling of their samples when loading and unloading the rotor.
