Abstract
An acceleration sensitive indicator for indicating a centrifugation status of a biological sample, a sample container comprising the indicator, a centrifuge for centrifuging samples and an analytical system for analyzing centrifuged samples are disclosed. The indicator comprises at least one closed chamber, formed between two opposite surfaces, that comprises an indication zone that comprises at least two fluid transfer zones or at least one particle transfer zone. The at least one fluid transfer zone comprises a solid carrier phase and a fluid stabilized in the solid carrier phase or at least one non-stabilized non-Newtonian fluid having thixotropic and/or shear thinning properties. The at least one particle transfer zone comprises a particle stabilizing fluid comprising stabilized dispersed particles. The fluid or particles have a distribution with respect to the indication zone changeable upon application of a g-force above a threshold value, the change of distribution indicating the centrifugation status.
