Custom Inspection Systems for Other Pharmaceutical Products
Automated Inline Inspection of Cartridges, Primary Packaging and Packaging Components
Pharmaceutical products and primary packaging differ considerably in terms of geometry, material, surface properties, closure and manufacturing process. The inspection requirements are therefore equally diverse: dimensions must remain within defined tolerances, components must be assembled correctly, and visible defects or contamination must be detected reliably.
OCTUM develops custom machine vision and AOI systems for pharmaceutical applications that are not covered by the modular vial.inspect or ampoule.inspect solutions. These applications include cartridges, pharmaceutical containers, stoppers and closure components, tubs, trays, nests and visible seal characteristics.
Each inspection solution is adapted to the product, relevant quality characteristics, known defect types, product variants, cycle time and available installation space. Cameras, lenses, lighting, inspection software, product handling, machine communication and reject handling are considered as one coordinated system.
Depending on the application, inspection results can be documented, linked to product, batch, work-order or process data and made available for quality assurance and process analysis.

OCTUM transfers proven machine vision concepts to new products, primary packaging and production processes. Which characteristics can be inspected reliably is evaluated using the actual product, relevant defect characteristics and real process conditions.
Inspecting Cartridges Inline
Cartridges can be inspected from several perspectives during manufacturing, assembly or packaging. Depending on the product and process, possible inspection tasks include:
- Overall length, diameter and contour
- Stopper position and visible seating
- Presence and position of closure components
- Crimping and visible closure characteristics
- Tilting and assembly deviations
- Visible damage and surface defects
- Print, human-readable text and 1D and 2D codes
- Product and variant verification
The system design takes the cartridge format, glass colour, surface reflections, relevant tolerances, product handling and available inspection window into account.
Inspecting Visible Seal Characteristics on Tubs, Trays and Nests
For sealed tubs, trays, nests and comparable packaging units, the machine vision system can inspect visible characteristics of the cover and sealing zone.
Possible inspection characteristics include:
- Presence and correct position of the cover
- Path and visible completeness of the seal
- Interruptions and irregularities within the visible sealing zone
- Wrinkles, inclusions and visible contamination
- Damage to the cover, tray or edge area
- Contour and position of the packaging components
- Print, human-readable text and codes
The optical inspection evaluates visible seal characteristics. It does not replace physical leak testing, seal-integrity testing or seal-strength testing.
Inspecting Trays, Nests and Packaging Components
Trays, nests and other packaging components can be inspected for completeness and correct loading before subsequent processing, filling or packaging operations.
Possible inspection tasks include:
- Correct number and arrangement of products
- Presence and completeness of components
- Position and orientation
- Correct product and packaging variant
- Visible damage and foreign characteristics
- Labels, print, variable text and codes
The inspection station is adapted to the packaging format, product arrangement, machine cycle and intended reject strategy.
Inspecting Pharmaceutical Containers and Closure Components
OCTUM develops application-specific inspection stations for pharmaceutical containers, stoppers, caps, crimp components and other closure components.
Typical inspection tasks include:
- Presence and completeness
- Correct closure or component variant
- Position, orientation and visible seating
- Contour, geometry and dimensions
- Visible scratches, cracks, breakage and deformation
- Visible particles, stains and deposits
- Print, OCR, OCV and code inspection
Transparent, reflective or structured surfaces place particular demands on lighting, lenses and image acquisition. Technical feasibility is therefore evaluated using actual sample parts.
Is Your Pharmaceutical Application Not Listed?
Many inspection applications require an individually configured solution. The decisive factor is not simply the product designation, but whether the relevant quality characteristics are optically visible and can be evaluated reproducibly under real production conditions.
Together with the manufacturer, OCTUM evaluates product geometry, material, defect characteristics, tolerances, product variants, cycle time, available installation space, interfaces and documentation requirements. For new or particularly demanding applications, a feasibility study using known-good parts, known-defect parts and, where appropriate, limit samples is recommended.

Surface, Defect and Contamination Inspection
Depending on the material, contrast, defect size and image resolution, the camera system can detect visible scratches, cracks, breakage, chips, deformation, foreign particles, deposits, stains and other deviations. The achievable detection limit is determined for the specific application.
Adapted to the Product, Defect Characteristics and Production Process
A robust inspection solution results from the coordinated interaction of image acquisition, product handling, evaluation software, machine communication and reject handling.
When designing the system, OCTUM considers factors including:
- Product geometry and accessible inspection surfaces
- Material, colour, transparency and reflection
- Relevant defect characteristics and required detection limits
- Tolerances and measurement requirements
- Product variants and format changes
- Machine cycle and available inspection window
- Installation space and environmental conditions
- Triggers, encoders and other process signals
- Connection to the PLC, machine and higher-level systems
- Pass/fail decisions, reject handling and reject verification
- Operator interaction, recipe management and format management
- Storage and transfer of inspection data
- Maintainability, serviceability and expandability
Depending on the application, different camera technologies, lenses, lighting methods and evaluation algorithms are used. The appropriate components are selected based on actual products and the defect characteristics that need to be detected.

Inspection Systems for Regulated Pharmaceutical Processes
In pharmaceutical manufacturing, it may not be sufficient simply to identify defective units. User access, changes to inspection programs, quality-relevant inspection results and system events may also need to be managed in a traceable manner.
Depending on the intended use, requirements arising from GAMP 5, EU GMP Annex 11, EU GMP Annex 15 and 21 CFR Part 11 may be relevant to the inspection system and its integration into the quality process.
Depending on the project, OCTUM systems can incorporate functions including:
- User, role and access management
- Audit trail
- Controlled recipe and format management
- Version and change history
- Storage of inspection and event data
- Product, batch and work-order assignment
- Data integrity and traceability
- Interfaces to machine controls, MES and other systems
- Documentation supporting qualification and validation
Regulatory requirements apply to the operator, the intended use and the respective quality and validation concept. An inspection system alone does not establish regulatory compliance. However, it can provide technical functions and documentation that support qualification, validation and quality processes.
2. Evaluate Technical Feasibility
For new or demanding applications, OCTUM examines known-good parts, known-defect parts and, where appropriate, limit samples under realistic conditions. Image quality, feature contrast, defect detectability, camera technology, lenses, lighting and evaluation methods are assessed.

Which Pharmaceutical Products and Primary Packaging Can OCTUM Inspect?
OCTUM develops inspection systems for cartridges, pharmaceutical containers, stoppers, caps, crimp components, tubs, trays, nests, covers and other pharmaceutical product and packaging components.
For vials and ampoules, OCTUM provides the modular vial.inspect and ampoule.inspect solutions. Syringes and syringe components are inspected using application-specific syringe.inspect systems.
Can Visible Seal Defects Be Detected?
Yes. Under suitable image acquisition conditions, the system can detect interruptions, wrinkles, inclusions, visible contamination and deviations in position or contour within the sealing zone.
The optical inspection evaluates visible characteristics only. It does not replace physical leak testing, seal-integrity testing or seal-strength testing.
Is 100% Inline Inspection Possible?
Depending on the product, inspection characteristics, machine cycle and system design, the inspection system can be engineered to inspect every unit within the production process.
Technical feasibility and the detectability of each relevant defect characteristic are evaluated for the specific project.
Can Dimensions and Geometrical Characteristics Be Inspected?
Yes. Lengths, diameters, distances, heights, contours, angles and other geometrical characteristics can be measured without contact and compared with defined tolerances.
Resolution, part presentation, tolerances, reference parts and measurement system capability requirements are evaluated for the specific application.
Can the Inspection System Be Integrated into an Existing Production Line?
Yes. OCTUM integrates machine vision and AOI systems into both new machines and existing production lines.
Available installation space, product handling, machine cycle, control interfaces, operator interaction, reject handling and data requirements are considered during system design.
Are OCTUM Systems Suitable for Regulated Pharmaceutical Applications?
Depending on the project, functions such as user and access management, audit trails, controlled recipe and format management, data integrity, traceability and documented inspection results can be incorporated.
The specific system configuration depends on the intended use and the operator’s validation concept. The inspection system alone does not establish regulatory compliance.
When Is a Feasibility Study Recommended?
A feasibility study is particularly valuable for new products, small or low-contrast defect characteristics, transparent or reflective materials, tight tolerances, demanding cycle times or limited installation space.
It provides a reliable technical basis for selecting the camera technology, lenses, lighting, image quality and evaluation methods before implementation.
