Designed for use in conjunction with other test tubes or original blood collection tubes when smaller sampling is necessary.

• Polystyrene (PS)
• Excellent clarity
• Temperate Range: –10 to 50 °C
• Non-sterile

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.
