RoSS® Shell | Protection of single-use bags

The RoSS® Shell is the solution for Robust Storage and Shipping of biopharmaceuticals. It is a robust case designed to protect 2D single-use bags of any size and vendor in any process step. The shell is optimized for transport, freeze and thaw steps, in which manufacturers see product loss of around 1.5% with traditional methods. In over 300,000 RoSS® Shells sold the product loss was <0.001%.

100% Protection

RoSS® stands for Robust Storage and Shipping. Our protective shell system is adapted from the oyster and has numerous advantages. 

Due to a smart combination of materials, the single-use biocontainer has a 100% protective shell. The shells protect bags of any size and from any manufacturer. As closed tamper-evident system RoSS is stackable to increase storage density. 

For particularly small volumes, such as in cell and gene therapy, RoSS.KSET is the perfect option.

Single Use Bag Independent

RoSS® shells are available for all established single-use bag manufacturers and filling volumes. Single-use bag vendor-agnostic RoSS® shells 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.

Facts about the RoSS® shell

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. No product loss due to maximum durability and strength
  2. Ideal characteristics for an effective freezing and defrosting or thawing process
  3. Available for every single-use bag

More details:

  • Unique functionality and patented system
  • Adjustable for all 2D single-use bioprocess container (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

Can a sample bag be placed in RoSS®?

Yes, sample bags for various sizes, from small to several 100 ml, can easily be placed in RoSS®. This provides tamper-evident protection for the sample bag (or ID).

Upon request, RoSS® Systems are available for sample bags exclusively.

Can RoSS® be partially filled?

Yes, any partial filling volume is possible with the patented RoSS® technology. The most recent data sheet with all RoSS® versions and details regarding partial filling is available in the download area or via our contact form.

Which freezing technologies is RoSS® compatible with?

RoSS® is basically compatible with all standard freezing technologies, from static (lab) freezers to blast freezers and plate-based freeze-thaw units. For a scalable process and maximum product quality, we recommend the latter. Read more about Freeze-Thaw.

Which clean room categories can RoSS® be used in?

In any. In case of uncertainties, please contact Single Use Support GmbH.

Is the RoSS® Shell System tamper-proof?

There is a variety of options to seal RoSS® tamper-evidently (labels, cable ties, …) in order to make any unwanted opening of RoSS® evident.

Can a RoSS® unit be reused?

Generally, RoSS® is very robust and thus reusable – however, in order to guarantee the highest possible protection, we advise against it.

Do sterile connectors fit in RoSS®?

Yes. You can put a single-use bioprocess container with long tubing and sterile connectors into our RoSS® shells. In this video we will explain how easy this works.

Is RoSS® suitable for N2 applications?

Yes, RoSS® is suitable for temperatures up to -200°C (-328°F).

How does a CCU (Cryo Control Unit) work?

We developed a system called Cryo Control Unit (CCU) which is an insolation material styro foam piece that covers the shoulders of the single-use bioprocess container and the shell. CCU is meant for enabling the use of RoSS® shells in standard lab freezers or in blast freezers.

Should I fill the biocontainer inside the shell or outside the shell?

Yes, both options are possible. Either fill the bag and place it in the RoSS® System or place the empty bag in the system and fill it with a fully automated filling system, compact and with little air. Learn more about RoSS.FILL.
