At Eckert & Ziegler, our cassettes go beyond standard solutions; a large part of our resources is dedicated to the production of customized Modular-Lab cassettes according to customer-specific requirements, as well as the contract manufacturing of cassettes and components for third-party manufacturers. This is complemented by the development and automation of processes at customer request.

In our previous article, we provided insights into our cassette production in Berlin, presenting the processes, special features and challenges involved in meeting the highest requirements when manufacturing components for the GMP-compliant production of radiopharmaceuticals.
In this article, we will explore the core elements of cassette and process development along with our contract manufacturing services.
The quality of the materials used is crucial for the performance and safety of Modular-Lab synthesis cassettes. At Eckert & Ziegler, we collaborate with trusted manufacturers whose materials meet the highest standards.
All materials used are certified to comply with the highest regulatory requirements. Customers can choose from proven standard materials and specific solutions, including cartridges, tubing, and other components. These can be predefined by the customer or sourced by Eckert & Ziegler according to the specifications.

Eckert & Ziegler offers individualized adaptation of synthesis cassettes to existing system configurations – or optimizes system configurations to suit the desired cassette.
Our comprehensive process development can be implemented in two ways:
– Confidentiality-First Design: Customers can maintain intellectual property confidentiality, sharing only essential details for development.
– End-to-End Development: Close collaboration with customers to design cassettes, systems and processes
We ensure reliability through a comprehensive quality and delivery framework. Customer-specific needs can be addressed with tailored quality and delivery agreements, which among other things may include:
– Additional validations or customized test plans
– Retain backup sample definitions
– Audit rights
Thanks to our broad logistics network and experienced team, production and delivery can be carried out according to defined cycles and customer timelines.
The complete control over our production facilities in Berlin allows for quick implementation of changes and adjustments. This enables a high level of responsiveness, beneficial in addressing short-term requirements due to component discontinuations by manufacturers or the tracking of modifications by change management.

By closely integrating development and production at Eckert & Ziegler, we ensure that customers receive solutions tailored to their specific needs. Depending on the customer’s preference, there are two possibilities for realizing the project:
– We Design: Eckert & Ziegler develops the cassette design based on process requirements and transitions it into production
– You Design: Customers provide the final cassette design and commission the production at Eckert & Ziegler.
The Process – From Initial Request to Delivery
1. Request for Quotation: Submission of customer requirements.
2. Consultancy: Technical support as required.
3. Development: Joint preparation of specifications.
4. Test Cassettes: Provision and iterative optimization.
5. Production: GMP-compliant manufacturing and quality control.
6. Shipping: On-time delivery to the customer.
Eckert & Ziegler is built on flexibility. This is made possible by standard materials from renowned suppliers, which enable quick and easy reordering. System-independent solutions, i.e. development and production without direct Modular-Lab or Eckert & Ziegler system affiliation, enable the implementation of complex special solutions, e.g. for semi-automated handling. Finally, we also offer contract manufacturing for third-party systems. This adaptability allows the implementation of any customer-specific solution.

In addition to the continuous optimization of existing processes, Eckert & Ziegler is constantly working to set new standards. In the future, comprehensive technical solutions and tools will be used to accelerate production and quality control processes and further improve the quality. Examples of this include meeting new pharmaceutical requirements by implementing stricter cleanroom conditions or AI-supported quality control, which increases the efficiency of visual inspections.
With 15 years of experience in the development and production of synthesis cassettes, Eckert & Ziegler is your reliable partner for tailored solutions. From material selection and process development to production, we deliver everything you need – flexibly, efficiently and ready for GMP environments.
