  • Non-reactive with virtually all chemicals and biologics, including DMSO and DMF
  • Large label pocket allows easy readability of content information
  • ISO-compliant FEP spike port with septum protected from external contamination by an integral tear-open tamper evident cover (allows for safe, quick and gentle removal of cells)
