Unprecedented flexibility to fill well

Automated Bulk Drug Substance Filling Systems fully embedded in end-to-end process streams.

Several surveys have shown that more than the half of CMOs and Biopharma manufacturer still use manual filling to dispense and aliquot drug substance into primary packaging, such as single use bags and bottles.(1) Manual handling comes along with a higher potential risk of “human error”. With 7 out of 10 cases, human error is the biggest cause of operational errors.(2)

Automated filling systems are recommended by many market experts to reach the next level in drug substance management. Many users are starting to have initiatives for automation that proves the overall trend towards automated filling of drug substances.

7 reasons why RoSS.FILL outperforms

Automated systems, in general, help to reduce both contamination risks and the risk of human errors. Among all available systems for automated filling of drug substance RoSS.FILL, as bulk filtration, filling and draining platform for primary packages such as single use bags, bottles and vials, outperforms over its competitors with regards to several product characteristics.

1. Limitless Scalability

RoSS.FILL opens doors to unprecedented scalability in terms of both, number of bags and size of bags. For example, per rack it deals 100 single use bags with each 500mL or also 20 single use bags with each 20L and is therefore suitable for small volumes of cell and gene therapy, mABs or other early phase studies, but also for commercialized bulk drug substance. It is even possible to attach a second filling rack or more to the control unit which allows dispense and filtration of 400L or more of drug substance in one batch run.

2. Configurable for unprecedented process flexibility in bulk fill systems

Not only the option to attach additional bag or bottle filling racks to enlarge the batch volume size, but also flexibility in consumables is limitless. RoSS.FILL allows users to attach different manifold systems, pump and sampling tubings, bulk filtration filters and bag. The customized supply by Single Use Support and options to easily and quickly reconfigurable to different processes are well accepted among its customers and partners.

3. Resolving complexities in bulk filtration

A reservoir of knowledge and expertise at Single Use Support and its partners has relieved customers their worries – also with regards to filtration of bulk drug substances during filling process. Single Use Support literally filters complex influences to consider into hands-on and effective solutions.

4. Unrivalled throughput and speed

200 liters of bulk drug substance within 60 minutes helps the industry to skyrocket the efficiency and creates resources to improve the performance whilst reducing product loss through a closed and automated process system. On top of that, holdup volume is limited to only few ml due to the smart manifold design and construction of the platform.

5. Reliable availability with fast delivery

Tired of waiting for single-use bags with volatile lead times? Pave your way to independent reliability with Single Use Support and debottleneck your supply chain with fast delivery times from concept to shipment.

6. Independence of size and type of primary packaging and consumables

Choose your preferred single use container – Single Use Support takes care of the rest. The same applies to consumables e.g. single-use tubing assemblies

If you do not have preferences, we help you find the most optimal solution based on your requirements.

7. Part of an End-to-End solution

It will be of bigger importance to break free from silo thinking and to streamline the production environment. The risk of product loss will be diminished once the whole ecosystem from downstream to fill and finish is covered from one hand and the primary packaging is protected robustly through its whole journey.

This already is reflected in our BULK.STREAM process, which covers all relevant touchpoints: from testing, to filling, freezing, shipping, thawing and draining to fill the vials and syringes. This approach will be crucial to guarantee a controlled manner of transportation and will eliminate any chances of incompatibilities or damages.

There is no relevant difference in the following standard product characteristics for automated filling and filtration systems:

  • Designed for single use bags, bottles and vials
  • Flow rate: 0,04L/min to 12L/min
  • Dispense Accuracy: +/-10g for 1000-2000ml (depending on dispense rate)
  • Consumables adaptable: all manifolds, filtration, connectors
  • Compliance: 21 CFR Part 11
  • Software: developed to GAMP5, HMI based PLCs
  • Commissioning & Maintenance: FAT & SAT included. IQ/OQ, Training and Maintenance/Support optional
  • Staff Training: on request
  • Contamination risks: Low. When granting a closed system, contamination risks can be drastically reduced.
