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.

More solutions


RoSS.FILL CGT | Fill-Filtration

Fully automated platform system for aseptic filling of multiple small single use bags. Special designed for use in cell & gene therapies with batch sizes at low volumes. With its high filling accuracy, the platform provides filling for up to 36 bags with one rack - having the option to attach more racks.


ROSS.KSET | Protecting small single-use bags

RoSS.KSET offers the protection for drug substances with volumes less than 250 mL. The shell is robust, closed, safe and sterile – most suitable for cell and gene therapies or clinical studies.

For larger volumes, RoSS can protect one or multiple single-use bags in one shell.


RoSS.pFTU Lab-Scale

Compatible with single use bags of all sizes and manufacturers. Our lab scale freezer is the perfect solution for studies conducted in labs and, above all, if you want to start a controlled and scalable freezing process.


RoSS.PADL | Homogenizing Solution

RoSS.PADL is a scalable platform for cooling your single-use bag whilst gently massaging it to ensure there is a homogenous mixture of the solution. With the RoSS.PADL multiple cooling and massaging mechanisms can be placed side by side with one control system.
