A tiny device with a huge impact – Tulip Crowns change the centrifuge game. The Crown is designed to keep syringe contents in a virtually anaerobic atmosphere during centrifuging. Simply attach a Crown to the syringe plunger, harvest, then twist the plunger off. The Crown also has a bonus, self-sealing extractor port for cleanly removing contents from any layer of centrifuged tissue. Patent-Pending.
