RoSS.pFTU Large-Scale Hybrid

The Hybrid Freeze and Thaw Platform freezes and thaws larger volumes of drug substances in both single-use bioprocess containers and bottles. All in one: plate-based freezing of single-use bags, protected in RoSS shells, and air flow freezing of bottles control cold chain management of valuable liquids in both primary packagings.

RoSS.pFTU large scale with its hybrid option is compatible with single-use bags and bottles from all manufacturers and of all sizes up to 400L and beyond.

Advantages of controlled plate-freezers

Dark blue spots indicate a higher cryoconcentration. 
Fast & controlled freezing with a plate freezer enables a homogeneous freezing result.

Hybrid Freeze & Thaw platform system for freezing and thawing of larger volumes of drug substances in both, single-use bags and bottles.

  • Capacity 
    • Single-use bags: Up to 220 L and more, depending on bag type
    • Bottles: Up to 160 L and more, depending on bottle type
  • Freezing type
    • Plate-based freezing and thawing unit for single-use bags, protected in RoSS shells.
    • Freezing and thawing with air flow for bottles, protected in Bottle CCUs.
  • Usage for mid to large scale batch sizes. Scale-up for late phase studies or commercial production
  • Primary packaging independent: any bag vendor, any size. Bag or bottle.
  • Best product stability results for mABs and BDS
  • GMP-compliant, automated, at highest possible speed and accuracy
  • Freezes down to -90°C

Controlling freezing and thawing of bottles

The combination of the hybrid RoSS.pFTU Large Scale and the use of CCUs (cryo control units) for bottles enables homogeneity during freezing. CCUs are attached to single-use bags and bottles for cryogenic applications with airflow in air turbulence or blast freezers to control homogeneity and pressure at the last point of freeze.


Cryo Control Unit for Bottles

  • Insulation material made of styro foam
  • Vendor agnostic and applicable to all available types and sizes of bottles
  • Covers the bottle cap during freezing applications with air turbulence (blast freezing)
  • Avoids volcano cryoconcentration effect or bulging enabling homogeneous freezing results

Efficient freezing and thawing of vaccines with single-use technologies

The global distribution of any medical substance requires more than what meets the eye. Before a vaccine can finally be shipped, it needs to be safely processed and contained. Single use technologies offer a number of advantages that cover the entire biopharmaceutical process, including development, manufacturing and logistics.
