The increasing variety of single-use bag systems presents operators with new challenges. Different bag geometries mean more containers, higher costs, and an increased risk of errors.

A container for many bags – Less complexity in cleanroom environments

Single-use technologies have established themselves as the standard in biopharmaceutical production. At the same time, the diversity of different bag manufacturers also increases the complexity within production processes. Different geometries, connection situations, and dimensions often require multiple manufacturer-specific containers to be maintained.

This system diversity causes additional investment needs, increases storage requirements, and complicates standardization within GMP-regulated production environments.

Against this background, INEX – solutions GmbH has developed the Agnotainer® container concept, which is specifically designed for greater flexibility and less complexity through adjustable side walls.

Challenge: System diversity in single-use production

Modern biopharma plants often use single-use bags from different suppliers. Operators deliberately avoid dependence on a single supplier and need the flexibility to use alternative systems.

In practice, this often results in multiple container solutions per volume class. The consequences:

– Increasing investment costs
– Additional storage space requirements
– More complex logistics processes
– Higher documentation effort
– Increased risk of misallocations

Especially in GMP environments, standardized procedures can make a significant contribution to process safety.

Standardization instead of manufacturer dependence

The INEX Agnotainer® takes a different approach. Instead of maintaining multiple containers for different bag systems, the concept allows for flexible accommodation of various bag geometries within a volume class.

Adjustable side walls adapt to different single-use bag dimensions. At the same time, a variably positionable bottom connection point ensures optimal integration into the respective process.

This can significantly reduce the number of required containers, so that the need drops to 2 containers for 4 volume classes (100 l, 200 l, 500 l, 1000 l). For operators, this means more flexibility in procurement, storage, and production planning.

“Many companies want to make their supply chains more robust while simplifying their process landscape. This is exactly where the INEX-Agnotainer® comes into play,” explains Frank Servay, Business Development Manager at INEX and responsible for the Life Science sector.

Developed for modern bioprocesses

The INEX Agnotainer® was specifically designed for the requirements of sensitive production environments. Two adjustable side walls enable flexible accommodation of different bag formats. A front access door facilitates handling, cleaning, and inspection. Additionally, the stackable design supports space-saving storage and efficient use of cleanroom and storage areas.

If needed, the container can be supplemented with additional components, such as load cells or connections for electric tow tractors. This allows for the realization of individual process requirements.

GMP-compliant materials and tested quality

Made from stainless steel 304L, the INEX-Agnotainer® meets high requirements for corrosion resistance and hygienic design. Two defined surface variants are available:

– Glass bead blasted with a roughness < 1.2 µm
– Brushed #4 finish with a roughness < 0.8 µm

The GMP-compatible construction of the INEX Agnotainer® supports use in GMP-close production areas.

International certifications and approvals

In addition, INEX – solutions has extensive experience in stainless steel plant construction for regulated industries, as well as numerous certificates and international approvals.

“Our customers expect not only flexibility but also traceable quality and reproducible processes. That’s why hygienic design and manufacturing quality are at the core of our development,” states Heiko Hackel, Sales and Product Manager for Bioprocess at INEX – solutions GmbH.

Less Capex, Opex, and logistics effort

Besides technical advantages, standardization also offers economic potential. Fewer containers mean lower investments, reduced inventory levels, and simpler material flows.

Furthermore, the risk of mix-ups decreases. This can contribute to the stability and safety of production processes. Especially in times of volatile supply chains and increasing demands for production flexibility, this aspect is becoming increasingly important.

ESG and sustainability

Sustainability aspects are also playing an increasingly important role in the life sciences industry. Reducing the number of containers can decrease material usage, storage space requirements, and logistical efforts.

The higher benefit of a standardized solution also supports resource-conserving production concepts. At the same time, the reduced number of containers can help make internal processes more efficient.

Thus, the Agnotainer® addresses not only economic requirements but also ESG goals in resource efficiency and sustainable production.

Conclusion: More flexibility for biopharma production

The growing diversity of single-use systems presents new challenges for operators. With the Agnotainer®, INEX pursues a standardization approach that consolidates different bag geometries within a single platform.

The result is reduced complexity, lower investment needs, and greater flexibility, while maintaining high suitability for GMP-close production environments.

Outlook

As the use of single-use technologies continues to spread, the demand for standardized yet flexible solutions also increases. Topics such as supply chain security, multi-sourcing concepts, and reducing complexity are gaining further importance in biopharmaceutical production.

The trend in biopharma production is increasingly moving toward standardization, supplier independence, and higher process flexibility. Solutions that integrate different single-use systems within a single platform will become even more significant in the future.

Container solutions that combine various bag systems within a standardized concept help operators make their processes more robust, economical, and future-proof. The trend is moving away from manufacturer-specific single solutions toward flexible and scalable concepts.

The focus of INEX – solutions GmbH remains unchanged: high-quality, process-safe, and individually tailored stainless steel solutions for sensitive applications. With many years of experience in stainless steel plant construction and a clear commitment to quality “Made in Germany,” the company supports customers in implementing future-proof production concepts.
