Most centrifuges are not well suited to create PRP. This is because most centrifuges are designed to fit the vacutainers manufactured by Becton Dickinson (BD). Unfortunately, vacutainers are not FDA cleared as class II medical devices for creating PRP. In reality, vacutainers are class I medical devices intended for testing purposes only. Not only are vacutainers and other test tubes illegal to use for PRP preparation – they are also dangerous. Becton Dickinson says on their own website that all of their vacutainer tubes may contain endotoxins! So, please don’t put your patients and your medical license at risk – choose a centrifuge that is designed to fit class II medical devices that are FDA cleared for PRP preparation.
