Future-proof production: Robotics, AI, and barrier technologies for maximum safety

Maximum safety and minimal contamination risks – barrier technologies play a crucial role in the production of aseptic dosage forms to meet the increasing requirements of the new Annex 1. The expanded use of isolators, the reduction of glove interventions, and innovative simulation methods optimize production processes and enhance product safety. Our solutions offer a well-designed combination of advanced robotics, AI-driven error detection, and precise process simulation to ensure the highest sterility standards.

Increased use of isolators for maximum process reliability

The new Annex 1 requires the increased use of isolators in critical areas to minimize manual intervention and thus increase process reliability. These must guarantee Class A conditions in the cleanroom and ensure a unidirectional air flow in order to meet the requirements.

Suitable isolator solutions are part of Optima's turnkey expertise – because isolators in themselves are complex process systems that must form a unit with the filling and capping machine. 

Reducing Glove Interventions in Isolators

Minimizing glove interventions in isolators is a key objective of Annex 1—both for planned interventions, such as aseptic setup, and for unplanned interventions related to troubleshooting.

According to Annex 1, glove interventions are only permissible if they are justified based on a risk assessment within a Contamination Control Strategy (CCS).
Each installed glove represents a certain inherent risk, but the actual risk of glove interventions depends on multiple factors:

  • Frequency of interventions per glove position
  • Location of the glove port on the isolator
  • Timing within the process sequence
  • Duration of the glove intervention at a specific position

For example, a glove intervention in the dosing area, near open containers, presents a significantly higher risk than an intervention after capping, where containers are already sealed.

Stopper intervention – solved with robotics and AI

  • Robotic systems nearly eliminate the need for glove interventions.
  • A robotic arm equipped with an autoclaved tool and picker, combined with optical error detection, identifies misoriented stoppers, isolates them, and removes them fully automatically without efficiency loss.
  • Autonomous path planning: A digital twin calculates the robot’s potential movement sequences in advance to ensure maximum safety.
  • The robot cannot access “no-go zones,” preventing interference with First Air principles.

Glove integrity testing with RFID technology and wireless connectivity

Annex 1 requires regular integrity testing of glove ports using leak tests—conducted minimally at the beginning and end of each batch.

Optima provides specialized glove testing systems to verify glove integrity. Measurement data is transmitted wirelessly to the batch protocol for documentation. The correct assignment of the test disc, glove port, and glove is ensured via RFID technology, guaranteeing clear traceability of test results and glove interventions.

Simulation: a holistic approach to the complete system

According to Annex 1, airflow in critical production areas must be visually represented and documented in detail.

Optima uses state-of-the-art simulation methods to model these airflows. These simulations enable the early identification of potential improvements, ensure the First Air principle is maintained, and can seamlessly integrate into our customers' Contamination Control Strategy (CCS).

Our expertise at a glance
  • Airflow simulations for visualization and documentation in accordance with Annex 1
  • Smoke Studies "At Rest" and "In Operation" during qualification
  • Simulations for all critical system areas under the isolator as a unified entity
  • Early identification of optimization needs in turnkey lines
  • Development & optimization of the decontamination cycle based on CFD study

Transfer of equipment, materials, and components into class A cleanroom

According to Annex 1, all required materials and components must be sterilized or treated through a validated decontamination process before being transferred into Class A. The introduction and removal of materials should be spatially separated or, if this is not possible, temporally separated to avoid cross-contamination.

RTP ports for transfer in cleanroom class A

RTP ports for transfer into class A cleanroom:

  • Different variants for opening RTP ports from the outside:
  • Manual operation
  • Motorized, fully automated solution
  • Avoidance of glove interventions and manual processes
     

Automated handling system for transferring the sorting vessel in high-speed systems:

  • A swivel arm picks up the autoclaved sorting vessel with a lid from a position before the isolator and transports it to the designated position in the system with open doors.
  • No handling by operators in critical areas of the sorting vessels
