Globe Scientific 5504 Polystyrene Nesting Sample Cups, 13mm Dia, 30mm Height, 1ml Capacity (Pack of 1000);

The nesting sample cup is used when smaller sampling is necessary. It is used in conjunction with other test tubes or original blood collection tubes. To use, simply transfer the sample from the original collection tube into the nesting cup. Then, place the nesting cup inside the original collection tube. The nesting cup "rides" along with the originally labeled/barcoded tube in the analyzer. This procedure saves time by eliminating the need to re-label the smaller sample.
