Celsius® FFTp: Compact SU Containers Perfect for Horizontal Plate Freezers

Designed for horizontal plate freezers, Celsius® FFTp (Flexible Freeze and Thaw for Plate Freezer) offers all the advantages of the Celsius® FFT with the unique bag-in-shell system, but with a flatter, more compact design to fit perfectly to the surface of the plate freezer, maximizing the heat transfer for uniform, fast and reproducible freeze and thaw processes, alleviating the concern of cryoconcentration. With Celsius® FFTp, you can bring the Sartorius standard of quality to your existing freeze and thaw infrastructure.

Protect bulk drug substance

Unique bag design, with secured tubing stowage, protects high-value BDS and ensures uniform freezing and thawing

Simplify freezing and thawing operations

Pre-assembled containers are designed with the end-user in mind, facilitating filling operations

Designed for horizontal plate freezers

Fast and reproducible thermal cycling combined with the monitoring and control of critical process parameters removes the risk of cryoconcentration

Facilitate shipping and handling

Celsius® FFTp can be shipped in pre-qualified single-use box shippers for simple frozen transfer

A Complete Container Assembly for Horizontal Plate Freezers

Celsius® FFTp is purpose-designed for horizontal plate freezers and engineered for reliable performance in conventional cold chain environments. The container system effectively protects bulk drug substance without compromising versatility. It’s easy to fill and, with its purpose-designed box and bulk shippers, it’s easy to transport.

Celsius® FFTp with Safecore™ Technology

Celsius® FFTp with Safecore™ Technology freezing containers feature an innovative cassette design, bringing together a semi-rigid bag composed of two polyester plates and a bag assembly protected by a surrounding shell. The plates secure the bag and lines by adding impact resistance, suppressing wrinkles and restricting degrees of freedom. The excellent bag-to-plate contact provides higher robustness and more uniform freeze and thaw.

Manufacturers that use Celsius® FFTp with Safecore™ Technology benefit from:

  • A flexible solution that can be used with horizonal plate freezers, working within existing infrastructure
  • Proven performance down to -80°C
  • Simplified operation, with an integrated line management system for secured tubing, pinch-clamp and connector stowage
  • Pre-qualified shipping solutions for safe international transportation
