Safecore™ bag-in-plate (cassette) design
  • Plates protect the bag and lines by adding impact resistance, suppressing wrinkles and restricting degrees of freedom
  • Excellent bag-to-plate contact provides higher robustness and more uniform freeze/thaw, plates compress the bag reducing ice bulging formation
  • Container assembly is tool-free and intuitive for minimum risk during production assembly
Maximum Robustness down to -80°C
  • Materials selection based on characterization of physical and thermal properties across wide temperature range to ensure suitable use for the intended application
  • Handling and shipping qualification built on deep understanding of mechanical stresses occurring during lifecycle for high confident performances against real-world environment
  • Storage and shipping operations down to -80°C, multiple freeze-thaw cycles, shipping qualification according to ASTM D4169 at Assurance Level 1 method
Simplified Operations
  • Plates are transparent with bag chamber fully visible for product inspection
  • Configurable with various connector/disconnector technologies, easy wipe down
  • Sample bag compartment to store/ship sample bag, label adhered to the shell for full product traceability, label placard for end-user labelling
Shipping Solution
  • Celsius® Box Shipper, qualified according to the most restrictive regulations for shipping containers
