BD Vacutainer plasma preparation tubes are used for the collection of venous blood, which upon centrifugation separates undiluted plasma. These are used in molecular diagnostic test methods or other procedures where an undiluted plasma specimen is required. BD PPT tubes are available in plastic only and contain spray-dried K2EDTA and a separation gel that forms a barrier between the plasma and most of the cellular elements, allowing for transportation of BD PPTTM tubes without removal of the plasma. A pearlescent white cap can identify BD PPTTM tubes. Centrifugation should take place within two hours after blood collection for optimum results.
- Mixing recommendation: plasma preparation tubes should be gently inverted 180° and back 8-10 times
- Centrifugation instructions: 1100-1500g for 10 minutes at 25°C room temperature
