Glass systems cannot perform reliably at these temperatures – having the potential to fracture and lose container closure integrity. Polypropylene (PP) systems can perform well at these temperatures – but they are opaque, which prevents visual inspection. At the International Society for Cell Therapies Annual Meeting, Montreal, Dr. Alex Lyness, Manager, Research & Technology, addressed this in a poster entitled: Evaluation of a Novel Cyclic Olefin Polymer Container System for the Cryopreservation of Adherent and Suspension Human Cell Types.

The performance of container systems comprising Daikyo Crystal Zenith^® cyclic olefin polymer (COP) vials was evaluated. Not only are COP vials break-resistant and completely transparent, this research demonstrated that COP vials enabled recovery of two different cell types (bone marrow and umbilical cord-derived) equal to PP systems. Further research is ongoing.
