As pharmaceutical manufacturing becomes increasingly automated, package inspection needs to keep pace with production demands. Container closure integrity testing (CCIT) and seal inspection are important parts of pharmaceutical packaging quality, particularly for products where package integrity is critical.
Automated inspection can help manufacturers increase testing capacity, reduce manual intervention, and create a more consistent and traceable inspection workflow.
PTI provides automated inspection solutions designed for different package formats and applications, including VeriPac LPX, E-Scan RTX, and Seal-Sensor PQX.
Why Is Automated Inspection Important for Pharmaceutical Manufacturing?
Manual inspection can require operators to handle samples, initiate tests, record results, and move products through different stages of the inspection process. As production volumes increase, these activities can limit testing capacity and introduce additional opportunities for operator-dependent variability.
Automated inspection can streamline these repetitive activities by combining testing with automated sample handling and result collection.
Depending on the application, automation can help manufacturers:
- Increase testing capacity
- Reduce manual sample handling
- Improve consistency
- Reduce operator-dependent variability
- Automate result collection
- Improve data traceability
- Support production-line inspection
The goal is not simply to make testing faster. It is to create a controlled and scalable inspection process that can support modern manufacturing requirements.
What Are PTI's Automated Inspection Solutions?
PTI's automated inspection portfolio includes three key solutions:
- VeriPac LPX – automated package and container closure integrity testing
- E-Scan RTX – automated CCI testing for parenteral products (pre-filled syringes)
- Seal-Sensor PQX – automated pouch seal inspection with built-in conveyor for easy handling
Each solution combines automation with a specific PTI inspection technology to address different package and application requirements.
How Does VeriPac LPX Support Automated CCIT?
VeriPac LPX is an automated package integrity testing solution based on PTI's Vacuum Decay technology. The system is designed to automate package integrity testing while reducing manual sample handling. For suitable applications, automated handling can move samples through testing and separate accepted and rejected products.
VeriPac LPX can support applications ranging from laboratory and batch release testing to production environments, helping manufacturers increase inspection capacity while maintaining quantitative, non-destructive testing.
How Does E-Scan RTX Support Automated CCI Testing?
E-Scan RTX is a fully automated container closure integrity testing solution designed for pre-filled syringes. The system uses PTI's HVLD technology together with automated robotic handling. Syringes can be automatically moved through the testing process and directed to the appropriate pass or reject location.
E-Scan RTX is designed for applications ranging from laboratory testing and batch release to high-volume production. Its automated workflow can reduce manual handling while providing rapid test results.
How Does Seal-Sensor PQX Support Automated Seal Inspection?
Seal-Sensor PQX is a fully automated pouch seal inspection and handling system. It uses PTI's Seal-Sensor Airborne Ultrasonic technology to inspect pouch seals online. The system incorporates automated handling and can identify defective seals and remove rejected pouches from the production process.
For manufacturers requiring high-volume pouch inspection, this provides an alternative to relying solely on manual or sampling-based seal inspection.
How Can Automated Inspection Support Batch Release?
Batch release involves the review of multiple quality attributes before a product can be released. Package integrity testing can become part of this workflow, particularly when large numbers of samples need to be tested and reviewed.
Automated inspection can support the process by:
- Increasing testing capacity
- Reducing manual handling
- Providing consistent test execution
- Generating clear test results
- Capturing test data electronically
- Improving traceability and data availability
PTI's VeriPac LPX and E-Scan RTX can support batch release applications where appropriate.
However, automated inspection does not independently determine whether a batch can be released. The final release decision remains subject to the manufacturer's quality system, procedures, acceptance criteria, and applicable regulatory requirements.
The benefit of automation is that it can make the inspection portion of the quality workflow more efficient and scalable.
What Should Manufacturers Consider When Selecting an Automated Inspection Solution?
The appropriate automated solution depends on the package, product, inspection objective, and production environment.
Manufacturers should consider:
- Package format: Size, shape, materials, and closure design can influence solution selection.
- Product characteristics: Product properties can affect the suitability of a particular inspection technology.
- Inspection objective: Requirements may include package leak detection, CCIT, or pouch seal inspection.
- Production requirements: Testing volume, throughput, handling, and line integration should be considered.
- Data requirements: Electronic data collection and traceability may be important for quality operations.
- Validation: The selected inspection method and automated system must be demonstrated to be suitable for the intended application.
No single automated inspection solution is appropriate for every package.
What Are the Benefits of Automated Inspection?
When appropriately implemented, automated inspection can provide manufacturers with:
- Increased inspection capacity
- Reduced manual handling
- More consistent testing
- Automated product handling
- Integration with production workflows
- Reduced operator-dependent variability
These capabilities can be particularly valuable for manufacturers managing high production volumes or seeking to reduce testing-related bottlenecks.
Conclusion
Automated inspection can help pharmaceutical manufacturers improve package testing efficiency by increasing inspection capacity, reducing manual intervention, and providing more consistent and traceable results.
By combining these automated solutions with PTI's inspection technologies, manufacturers can create scalable workflows for laboratory testing, batch release, at-line inspection, and production environments.
Automation does not replace quality controls or the manufacturer's batch release process. Instead, it provides a way to make package inspection more efficient while maintaining the testing and quality requirements of the specific application.
