The disclosed apparatus, systems and methods relate to technology that provides a method for the assessment of the polymerization of a sample, e.g., whole blood or blood plasma coagulation, by a non-contact acoustic tweezing device via the application of a sweeping frequency to the levitating sample and the corresponding assessment of extracted sample parameters.

The present invention relates to a transfer platform for a biological sample analyzer, comprising a movable carrier plate and an object stage which is placed on the carrier plate and separable from the carrier plate. The side of the carrier plate facing the object stage is an upper surface, and the reverse side is a lower surface. The side of the object stage facing the carrier plate is a lower surface, and the reverse side is an upper surface. The object stage and the carrier plate are respectively provided with magnetic blocks that magnetically attract each other. When the object stage is placed in a predetermined area on the carrier plate, the suction of the magnetic blocks automatically positions the object stage relative to the carrier plate, thereby achieving the technical effect of blind positioning. The present invention can be applied to test analyzers for specific proteins, cholesterol, heme, routine urine test, dry biochemical test, etc. The present invention has the advantages of convenient operation, time and effort saving, high efficiency and the like. Meanwhile, the present invention is simple in structure and low in cost, and is suitable for wide promotion.
