Vacutainer

A 4ml Vacutainer produced by Becton Dickinson is utilized for blood sample collection via vacuum technology. The vacuum mechanism draws blood from the vein. To ensure accurate measurements, I returned the tube unharmed and referred to BD's images for designing the internal dimensions. Although the accuracy may be within +/- 1mm deviation, I will update if I can dismantle a tube for improved precision.
