What is the benefit of a so-called kit rotor?
When working with nucleic acid purification kits with spin columns by certain manufacturers, sometimes tube lids cannot be closed any more. This means you have to centrifuge with open tube lids. These tube lids might rip off during the stress of centrifugation and might damage the centrifuge. In order to prevent this, the kit rotor with the raised rotor rim was designed. Open tube lids, supported against the rim, will not rip off during centrifugation. Another feature of this rotor is the enlarged distance between the rotor bores. The enlarged distance between the bores offers a very convenient handling when loading / unloading the rotor. Especially when working with long spin columns (e. g. from Princeton Separations) you will need a larger distance between the bores to load the rotor fully and make use of the complete rotor capacity.
