ABSTRACT:
The serum transfer cup is nestable in two different size blood collection tubes such as a 13 mm diameter sample tube and a 16 mm diameter sample tube of the same axial length. The serum transfer cup includes a flange stepped down from a top edge of the cup by a distinctive axial distance that permits ultrasonic identification of the presence of the serum transfer cup regardless of which sample tube nests the serum transfer cup. The serum transfer cup has a higher elevation in the 13 mm sample tube than in the 16 mm sample tube, and the different flange heights can be detected using ultrasonic signals. Thus ultrasonic measurement of the flange position of the nested serum transfer cup identifies the presence of different serum transfer cups in the 13 mm sample tube and in the 16 mm sample tube, and also identifies the 13 mm and 16 mm sample tubes with the nested serum transfer cups.
