Our customers trust in us:

3SBio Inc.

The combination of a bag agnostic robust secondary packaging (RoSS®) and the scalable plate based freeze/thaw technologies convinced us to select Single Use Support. It not only matches all our requirements, it is also safe, easy to navigate and flexible to single use bags from any supplier.


Thanks to a fortunate coincidence, we got in touch with Single Use Support. Not only have we found a more than solid single-use solution for our main problem thanks to their product RoSS®, but we now have access to a clever and 100% safe drug substance logistics system.


Having partners such as Single Use Support in place will be one of many essential components as we scale our operations to deliver high-quality programs and vector production services to our clients.

Advantage of the high density ultra cold storage platform RoSS.FRDG

  • Great relief for ultra cold room storage capacities due to its high storage density and stackability of RoSS shells
  • Seamless transitions between deep-freezing (RoSS.pFTU) and shipping (RoSS.SHIP) or thawing in an end-to-end process
  • High degree of flexibility in-plant due to its portable use
  • strong helping hand in-plant to prevent staff from carrying heavy loads manually
  • Another way out from incompatibilities of technologies due to its tailored design


  • Insulated container for long-term cooling of drug substances in RoSS Shells
  • Ease of use for loading: place loaded Trolleys or Racks as a whole inside
  • Space for 1 pallet or one rack. Alternatively, RoSS can be loaded in shelves.
  • GMP compliant alarm management
  • Temperature monitoring
  • Modular system: stackable, movable, shippable. Flexible storage location.
  • Ultra Low Freezer: Holds desired temperature down to -80°C
  • Place your RoSS shells into shelves or in racks and trolleys to load RoSS.FRDG
  • Compatibility to RoSS single-use technologies
  • Contains up to 300L of drug substance
  • Amount of condensation depends on temperature, humidity and other factors

What are ultra cold freezers?

Ultra cold freezers, also known as ultra low temperature freezers or ULTs, are refrigerated that are designed to achieve temperatures as low as -40 to -86° C. They represent a significant component in the supply chain of various products, including most innovative biologics.

What are ultra low temperature freezers used for?

Ultra low temperature freezers are designed to achieve extremely low temperatures, required for example for a safe storage of many biologics.

What is the coldest freezer you can buy?

While cold freezers achieve temperatures of -40 °C or lower, ultra cold freezers usually operate at temperatures between -40 and 86 °C. Thus, they are able to meet lab requirements, where temperatures around -85 °C have to be achieved.

Introducing the next level of single-use freezing and thawing technologies

While the auto load function is a fantastic new tool, the well-established utilization of advanced single use technologies facilitates a safe and protected handling of highly valuable and sensitive drug substances throughout the entire process. The RoSS.pFTU freeze thaw platform contributes to a safe journey and warrants the bottle’s or single use bag’s intact arrival at its final destination, keeping its precious contents protected from biocontamination and other damages. Furthermore, the plate freezer unit is scalable for volumes of up to 200 l and offers the option of user-specific regulation and adaptation.


Single-use technology & the implementation in biopharma

Single-use technologies, which reduce the risk of cross-contamination of high-quality bulk drug substances, are becoming increasingly popular in the pharmaceutical industry. You can find out the reason for this in the blog post!
