Mobius® PureFlex™ Film Technology


PureFlex™ Single-use process container films are flexible, robust and chemical resistant materials used in the construction of our single-use process containers, including Mobius® assemblies and NovaSeptum® sterile sampling products.

Single-use containers made with PureFlex™ films are employed throughout the biopharmaceutical production process and are free of animal derived components.

PureFlex™ Plus Film

For particularly demanding applications often encountered in large volume operations (>500L), the additional robustness of PureFlex™ Plus film may be required to assure single-use process container integrity. This film is also suitable for use throughout the manufacturing process.

More Details
  • Fluid contact material: Made of ultra low-density polyethylene (ULDPE), which is identical to PureFlex™ film and maintains the same extractables profile.
  • Gas barrier: Made of polyethylene vinyl alcohol-copolymers (EVOH), which is identical to PureFlex™ film and maintains the same gas barrier properties.
  • Outer layers: Constructed of a linear low density polyethlene (LLDPE) that increases the film's resistance to leak formation through abrasion, puncture, stretching, and tearing.
