Fully automated bulk filling & draining.


RoSS.FILL is a flexible platform for the allocation and distribution of bulk drug substance in single use bags that are integrated in the RoSS® system. The liquid path is fully disposable and can accommodate a multitude of sterile compound- and segregation options.

With a filling speed of 200 liters per hour, the RoSS® units on the rack are filled in a fully automated manner. Single use bags of all established manufacturers and of different sizes and capacities are compatible. The scalability is limitless.


  • Fully automated filling and draining system for single use bags
  • Filling of up to 200 liters of substance in less than 1 hour
  • Accuracy of +-10 ml for 10 liters with individual weighing cells
  • Modular system with separate control unit and pumping station as well as storage rack made up of RoSS trays filled with single use bags
  • Option to take samples
  • Optional MES integration


Fully automated, effective filling & draining process – what more could one wish for?

We see issues with integrity of Single Use Systems in the biopharma world. Potentially, the MITS.2D technology is able to help address Endotoxin and Bioburden issues properly. Sterility is key for some applications very close to the patient in Fill and Finish facilities. Midterm, MITS.2D might be able to mitigate the risk of biocontamination in these process steps also.

We were looking for a solid shipping solution for our single use bags. None of the available solutions to date offered reassuring solutions.
Thanks to a fortunate coincidence we got in touch with SUSupport. Not only have we found a more than solid 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.

The Single Use Filling System - RoSS.FiLL

When developing the BulkStreams, our focus was on developing a logistics process for single use bags.  Why? The single use bag has its established role in modern biopharma.
The entire “drug substance logistic” process can be managed with a single tool - the single use bag. It boasts a range of advantages, from compatibility in the handling process to a range of available volumes to extremely low storage capacity and immediate availability - to name just a few of the countless arguments in favor of the single use bag.

And this has driven us to develop a  100 % safe logistics process around the single use bag. Obviously, we have not forgotten about the fill & drain process either und have developed a fully automated single-use bag filling system, the RoSS.FILL, which allows for maximum flexibility and scalability of both the filling and draining process. Volumes of up to 200 L can be filled in less than an hour. Furthermore, the entire filling path is fully disposable, thus warranting an absolutely sterile fill & drain process.

And this is what makes our single use filling system truly stand out:

RoSS.FILL is the perfect single use filling system for all companies in the biopharmaceutical industry that are already using single use containers or are planning to do so. It is compatible with all single use bags from established manufacturers, which means that you can use any single use bag with our Bag filling System. You only need one system for filling and draining: RoSS.FILL.

All the advantages of our single use filling system at a glance:

• compatible with single use bags of all established manufacturers
• unrestricted scalability and flexibility
• 100% sterile filling and draining
• fully automated filling and draining of single use bags
• fast filling at a rate of up to 200 L per hour

Our single-use filling system is a modular system with separate control and pump units as well as a storage rack for RoSS trays containing single use bags.  The RoSS trays act as a protective shell for the single use bags throughout the entire process from downstream to fill & finish.

The single use bag is embedded in a 3D foam layer, which in turn is secured by a high-quality stainless steel shell. Thus, if the single use bag is contained in a RoSS® shell system, we expect external and mechanical impact to be eradicated as a reason for “loss of drug substance”.
