BD Vacutainer® PPT™ is a closed system allowing separation and storage of undiluted EDTA plasma in the primary blood collection tube. It is intended for the purposes of molecular diagnostic testing.
PPT™ is an evacuated, sterile blood collection tube that contains an inert gel and spray-dried K2EDTA anticoagulant for achieving plasma separation. When the sample-filled tube is subjected to centrifugation, the gel migrates and forms a physical barrier between the plasma and most of the cellular elements. Since the tube uses spray-dried K2EDTA as opposed to liquid additives, the plasma obtained is undiluted.
Features
- When the tube is centrifuged, the separation gel migrates and forms a physical barrier between the plasma and most of the cellular elements
- Spray-dried K2EDTA anticoagulant (as opposed to a liquid additive) is used so the plasma obtained is undiluted
- The PPT™ tube can be transported without removal of the plasma, due to the stable, inert separation gel
- Centrifugation should take place within two hours after blood collection for optimum results
