The CellSeal® vial is different, like your therapy. It’s radical. It’s disruptive. The CellSeal vial is unlike conventional bags and stoppered or screwcap vials because of its unique design. It is created from USP class VI materials chosen specifically for their resistance to chemicals, durability under true cryogenic temperatures, and maximum cell recovery upon retrieval.

This difference in the design means you get:

  • Consistency: uniform freezing and thawing profile
  • Durability: fracture resistance
  • Safety: heat sealed to prevent contamination
  • Usability: maximum recovery
  • Flexibility: multiple fill ports and sizes
  • Scalability: choice of manual or automated filling
