Whitepaper: RoSS.pFTU - Controlled scalable freezing

As one of the most essential parameters in terms of achieving control over freezing & thawing bulk, the freezing rate has been considered and evaluated in different tests. Using the ice front growth speed as a leverage had a significant impact on controllability and, as a result, on protein quality.

Whats makes our freeze-thaw platforms so special?

Fully automated
Fully-automated freeze & thaw process, at highest possible speed and accuracy. CFR Part 11 and GMP-compliance as a further milestone for the biopharma manufacturers. Freeze/thaw recipe for lab scale also transferable for large scale.
Unrestricted Scalability
Fully scalable and compatible with all batch sizes and bags from all established manufacturers – you will only require one single system from the lab to blockbuster production. From 10mL up to 50L bags and a batch size of up to 500L and more you can scale-up or down as required.
Flexibility
Compatible with single-use bags of all established manufacturers, sizes and capacities. Hybrid version of plate freezers to freeze & thaw vials, bottles and single-use bags in one platform possible. Or blast freezing technologies for controlled rate cryogenic down to -170°C.
Safety
Taking the safe and controlled freezing of high-value biopharmaceuticals to a new level: A tamper-evident closed system with optimal freezing kinetics leads to proven product viability and a freezing process with best stability results for mABs, BDS, CGT, ADCs, viral vectors or any other vaccine.

Advantages of controlled rate plate freezers

To demonstrate the effects of cryoconcentration with different freezing techniques, Naphthol Blue Black was used as a visual marker. The intensity of the blue coloration indicates the concentration of dissolved substances within the frozen solution.

Slow uncontrolled freezing (A)
The bag frozen in a static freezer shows uneven solute distribution. Dark blue areas, especially in the lower regions of the bag, highlight significant cryoconcentration.

Fast controlled freezing (B)
The bag frozen using our plate-based controlled rate freezer shows a uniform distribution of solutes. The result is a consistent, light-blue hue with a distinct white line through the center indicating minimal cryoconcentration.

The close contact between freezing plates and liquid substance within the plate freezer significantly speeds up the freezing process, resulting in homogeneous freezing with controlled ice front growth from the bottom and top preventing the effects of cryoconcentration.

Frequently asked questions

What is the difference between a blast freezer and a plate freezer?

+

While blast freezers use cold air that is blasted on products that are yet to be frozen, plate freezers work via direct contact between the cooled plates and the products.

What is plate freezing application of refrigeration?

+

The fields of application of plate freezers are manifold, since they are able to deliver a very consistent and fast freezing process. Therefore, they are, for instance, an essential tool in biopharma industry, where the quality of highly delicate products needs to be maintained when bringing them to ultra-low temperatures.

What is a pharmaceutical-grade freezer?

+

A pharmaceutical-grade freezer is a freezer that is designed to freeze and store pharmaceutical substances – for instance vaccines – in a secure and efficient manner. In order to be able to cope with the high fragility of these products, there are several aspects in which they differ from ordinary kitchen freezers.

What is a medical freezer?

+

Medical freezers are specifically designed to store medical substances. Since these goods come with specific needs, the according devices have to meet several criteria that set them apart from ordinary household freezers.
