Package Integrity Testing Using VeriPac Series

Package Integrity Testing Using VeriPac Series

Medical devices and pharmaceuticals products are manufactured with zero tolerance to defects. For this reason, manufacturers give top priority to quality control procedures and regulatory standards. This is to make sure that products maintain the quality standards required for their intended use.

Packaging plays an important role in maintaining product quality and ensuring the product reaches consumers defect-free. While selecting the right packaging material is important, testing integrity of packages also holds high relevance. Traditionally, destructive testing methods like Dye Ingress and Water Bath were popular Container Closure Integrity Testing (CCIT) techniques. However, in recent years, the industry has moved towards deterministic methods to achieve more precise, reliable results.

How PTI's VeriPac Series ensure package integrity?

PTI 's VeriPac series are non-destructive, non-subjective test systems ideal for leak testing high-risk applications that require extreme levels of test reliability and accuracy. This technology uses an ASTM approved vacuum decay leak test method F2338, which is listed in ISO 11607, USP <1207>. It is an FDA recognized consensus standard for package integrity testing. Using cutting-edge innovation, VeriPac inspection systems provide repeatable, sensitive, and more robust detection of defects. VeriPac testers feature the patented PERMA-Vac manifold system and dynamic test modes that provide the ability to test a wide range of package formats including flexible, rigid and semi-rigid packaging. Apart from package integrity testing, VeriPac technology can also be used for stability studies, clinical trials, quality assurance testing and statistical process control (SPC).

Technology Overview

The test method is initiated by connecting VeriPac leak testers to a test chamber that is specially designed to contain the package being tested. The package is placed inside the test chamber to which a vacuum is applied. Using a single or dual vacuum transducer technology, the level of vacuum as well as the change in vacuum over a predetermined test time are monitored. The variations in absolute and differential vacuum indicate the presence of leaks and defects within the package. The sensitivity of a test is a function of the package design, the package test fixture and critical test parameters of time and pressure. Test systems can be designed for manual or automatic operation. This inspection method is suitable for laboratory offline testing and production applications for QA/QC statistical process control. The test cycle takes only a few seconds, is non-invasive and non-destructive to both product and package.

Benefits of VeriPac series

  • Deterministic, quantitative test method.
  • Defect detection down to 0.034 cc/min.
  • Highest level of repeatability and accuracy.
  • Cost-effective with rapid return on investment.
  • Simplifies the inspection and validation process
  • Results proven superior to dye ingress.
  • ASTM test method and FDA standard
  • USP <1207> Compliant.

Evaluating Quality Control Solutions for Parenteral Products

Evaluating Quality Control Solutions for Parenteral Products

Parenteral preparations are defined as solutions, suspensions, emulsions for injection or infusion, powders for injection or infusion, gels for injection and implants. They are sterile products intended to be administrated directly into human bodies. Parenteral drug products are expected to be free from microorganisms, pyrogenic substances as well as other visible particles. Contaminated parenteral drug products can cause serious health concerns to the patient. Hence, sterility assurance and package integrity testing are of paramount importance in parenteral drug manufacturing. Read on to know more about parenteral products package testing methods offered by PTI.

Parenteral products package testing methods:

1. Vacuum Decay technology

Vacuum Decay technology is a non-destructive Container Closure Integrity test method primarily used to detect leaks in package seals. Proven to be the most practical and sensitive vacuum-based leak test method, Vacuum Decay technology is capable of identifying leaks in sealed rigid, semi-rigid and flexible packaging made of non-porous or porous materials. It provides reliable, accurate and repeatable test results that ensure deterministic package testing and leak detection. Vacuum Decay technology has established itself as a non-destructive alternative to traditional test methods like Water Bath and Dye Ingress, making it a practical solution for leak detection in the Pharmaceutical and Medical Device industry.

How does Vacuum Decay technology work?

The principle behind Vacuum Decay technology is simple and it challenges container integrity based on fundamental physical properties. The test begins by placing sample packages in a closely fitting evacuation test chamber, which is equipped with an external vacuum source. Based on the test sample and level of sensitivity required, a pre-determined vacuum level is chosen for the test. The next step involves evaluating the test chamber and test system dead space for a pre-determined period. Differential pressure transducers are used to monitor changes in vacuum levels for a specified period. A pressure increase beyond the predetermined pass/fail limit indicates container leakage.

Benefits of Vacuum Decay technology

  • Non-destructive package inspection system
  • Accurate and reliable results
  • Definite pass/fail result based on quantitative test data 
  • Accommodates multiple packaging formats
  • Eliminates destructive, subjective testing methods
  • Effective in detecting even minute leaks
  • ASTM Test Method F2338, FDA Consensus Standard and USP 1207 compliant
  •  

2. MicroCurrent HVLD Technology

PTI’s Microcurrent is patent-pending unique CCI technology that has revolutionized the conventional high voltage leak detection method. It is a non-invasive and deterministic container closure integrity testing method that is effective across all parenteral and biologic products including low conductivity liquids such as sterile water for injection. The Microcurrent HVLD test method is highly effective in detecting the presence and location of pinholes, micro-cracks, stopper/plunger leaks, non-visible leaks under crimping and many other defects across applications like pre-filled syringes, vials, cartridges, ampoules, BFS, bottles and pouches. A unique mode of Microcurrent HVLD uses about 50% less voltage and reduces the exposure of product and environment to less than 5% of the voltage when compared to conventional HVLD solutions. The E-scan HVLD series is a leading solution of sturdy container closure integrity test equipment.

Benefits of MicroCurrent HVLD technology

  • Non-destructive & requires no sample preparation
  • Deterministic & non-invasive
  • Highly effective across all parenteral products
  • High levels of sensitivity, accuracy and reliability in results
  • Offline and 100% online inspection at high production speeds
  • Simplifies the inspection and validation process
  • Referenced in Chapter USP 1207 Guidance for CCIT
