What makes RoSS® so special for biopharma logistics?


Scalability – RoSS® is the basis for the highly effective end-to-end process solutions BULK.STREAM & SEED.STREAM. RoSS® and RoSS.KSET offer minimal storage volume and maximum strength. The RoSS® basis constitutes an industry standard for single use bags.

100% protective

Safety – thanks to the use of clever material setup the single use bag has a 100% protective shell. RoSS® stands for a safety upgrade for the biopharma process chain.

Single Use Bag Independent

RoSS® shells are available for all established single use bag manufacturers and filling volumes. Single-use-bag agnostic RoSS® fosters flexibility and 100% compatibility – no system change required.

High Storage Density

RoSS shells can be stacked one over another leading to huge savings in cold storage rooms and shipping costs and is easy to handle. RoSS® maximizes your storage density and minimizes your worries of requiring storage space.

How can RoSS® be 100% secure for single use bags?

The well tried-and-tested single use bag gets its 100% secure and compact shell.

In the first place, the single use bag will be covered by soft 3D foam, which provides a protective embedding as well as damping in case of vibrations.

Furthermore, the volume of the bag or of the liquid contained within can be expanded during the freezing process. This allows for a perfect adaption, which in turn maximizes the protective effect.

The frames of the RoSS® unit are made of heavy duty plastic that withstands even the lowest temperatures and makes up the static frame of RoSS®. Apart from the guide rails for the stainless steel top and bottom, the frame contains ergonomically shaped grip plates for safe and intuitive handling.

The RoSS® top and bottom are made of high quality stainless steel with the following three advantages:

  1. Maximum durability and strength.
  2. When in direct contact with the bag, these features offer the ideal basis for an effective initial and ongoing freezing process. Furthermore, they enable a consistent and gentle defrosting or thawing process.
  3. Thanks to the right compounds, tolerances and material strengths of the stainless steel top and bottom, the RoSS® construction allows for only minimal vibration.
    It also reduces the tension in the structure of the single use bag and offers shock absorbent protection.

Facts about the RoSS® shell:

  • Adjustable for all 2D single use bags (e.g. PALL, Thermofisher, Entegris, Sartorius, …)
  • Robust, closed and tamper-evident construction
  • 3D foam offers additional space and protection for the sensitive compound of the raw bag and tubing – complete immobilization <0 °C / <32 °F
  • Space for sterile connectors and long hoses
  • Space for satellite samples / ID bags
  • Steel plates on the top and bottom for consistent and quickest possible freezing and defrosting times
  • High density, which means a reduction of required freezer space capacity
  • Resisting vaporized hydrogen peroxide for decontamination without any long-term damage, visual changes or changes in the contact angle.
  • Easy handling during the recycling process – no composite materials
  • Bag can be visually checked/inspected after filling and before dispensing

Beneath its absolutely hard and robust shell, the oyster too embeds its pearl in a flexible and soft environment.

    The single use bag Shell & Protection System: RoSS®

    The single use bag is a tool that is indispensable in the “drug substance logistics” for the pharmaceutical industry. The reasons are simple: In biopharma, the entire process – from downstream to the fill & finish process – can be managed by using disposable bags. In fact, many biopharma processes are no longer imaginable without single use bags. Their compatibility, the various available sizes and capacities, small storing volume and immediate availability are powerful deciding factors.

    Advantages of single use bags in biopharma:

    • The single use bag is an industrial standard.
    • Single use bags require hardly any storage space and are cost effective.
    • Single use bags are available in various sizes and filling quantities.
    • Thanks to the different connectors, the system compatibility of single use bags is multifaceted.
    • Single use bag manufacturers can supply large quantities.
    • Single use bags are easy to dispose of after use.
    • Reduce the risk of loss of drug substance.
    • Tamper-evident packaging to avoid unnoticed manipulation or contamination.

    Why does a single use bag require a shell system?

    Single use bags have many advantages – but also potential disadvantages. The bags, which are made of thin plastic, are filled with liquid. In order to safely transport the liquid and protect its “functionality”, it is frozen prior to being shipped and then thawed before draining. (This is called the “freeze-thaw process of drug substance” and/or “cold-chain logistics“.) During shipping, the single use bag and its content may be exposed to shocks and tremors that may impact both the bag and its content. With a frozen bag container system like the RoSS® Shell-System developed by Single Use Support Gmbh, integrity issues, material loss and leakage or breakage of single use bags can be more or less eliminated. In other words, the process called “loss of drug substance” can be minimized. As a load kit for single use bags, RoSS® considerably increases patient safety!

    Why is it sensible to test single use bags prior to filling?

    We assume that the bag is located in 100% safe and protected surroundings – in other words, in the RoSS® Shell-System. Shocks, warehousing and integrity issues can be ruled out as possible causes for “loss of drug product”. 
So why is it sensible to test single use bags prior to their filling with “drug substances”? Upon delivery, disposable bags can exhibit minor material deficiencies or faults that can hardly be detected and thus go unnoticed. Considering the value of the contents of a single use bag it is more than reasonable to test the bag with regards to its full functionality prior to filling. What is the content’s value? “Drug substances” usually require many years of development and come at a certain price.

    A person or an institution on the other side of the world may be waiting desperately for exactly that substance for a certain treatment. Considering this urgency, one can understand the importance of ensuring the integrity of single use bags – even more so as it can be done in less than a minute thanks to the MITS.2D® System developed by Single Use Support GmbH. With its seemingly limitless flexibility, the single use bag is an almost invincible tool.

    It does have its weaknesses – but those can be compensated easily. And just like this, a disposable bag turns into a pearl that is thoroughly protected by the oyster. With the right choice of ecosystem for the single use bag, “loss of drug substance” will slowly but surely become a thing of the past.

    Process safety and the supply chain remain undisrupted, thus ensuring the patients’ safety.

    Protective single use system for CAR-T and other cell & gene therapies: The RoSS.KSET

    Single use bags have become a mainstay in the pharmaceutical logistics process, all the way from downstream to the fill & finish process. It’s area of application also range to ATMP and regenerative medicine: They are the ideal solution for small volumes required in cell & gene therapy approaches, such as CAR-T.

    Advantages of single use bags in biopharma:

    • Industrial standard.
    • Compact and cost effective solution.
    • Available in various sizes and filling quantities.
    • Easy to dispose of after use.

    Since single use bags are made of thin plastic they allow for ideal freezing results, yet, at the same time, they are sensible and require protection from external impact to reduce integrity issues, material loss and leakage or breakage.

    Effective protection with a soft core and a tamperproof shell

    Highly sensitive cell and gene material used for personalized therapies in ATMP such as CAR-T requires sterile and safe handling. In order to protect the valuable goods throughout the logistics process, the single use bag is embedded in a soft core made of 3D foam, which is then encased by a compact and tamperproof, highly dense stainless-steel sleeve.

    While the soft foam dampens external shocks, the stainless-steel shell adds an additional layer that is both impact-resistant and offers stability. For added functionality and safety, the RoSS.KSET is lockable, while product-specific data can be viewed through an inspection window, allowing for maximum transparency and easy handling.

    Advantages of RoSS.KSET at a glance:

    • Compatible with bags from all established manufacturers, ranging from 1mL to 500mL in volume
    • Compatible with any L2 DEWAR/Shipper
    • Fully immobilizes bags and tubings at < 0°C / 32°F
    • Offers space for satellite samples, ID bags and vials
    • Expandable foam core adjusts to size fluctuations during freezing/thawing
