Vacuum Decay

Vacuum decay has been substantiated as one of the most practical and sensitive vacuum-based leak detection method. This test most gives a reliable, reproducible and accurate quantitative result and a pass or fail determination. The ASTM F2338 standard vacuum decay test method was developed using PTI’s VeriPac instruments. It is also listed in ISO 11607 and referenced in United States Pharmacopeia Chapter on CCI.

High Voltage Leak Detection (HVLD)

PTI packaging and inspection systems revolutionized the conventional HVLD method and introduced a groundbreaking new technology for the integrity testing for all parenteral and biological products including low conductivity liquids such as sterile water for injection (WFI).

Helium Leak Detection

Helium leak testing is defined as the act of finding leaks in different types of enclosed or sealed systems using helium as a “tracer” gas and its concentration is measured as it escapes due to leakage. A vial, consisting of a container and elastomeric closure, is a good example of a package system. A vial is helium-filled & is subjected to vacuum.

Airborne Ultrasound

A strong seal is not necessarily an airtight one, and the flow of gas or liquid through the seal (leak) is just one type of seal defect. As such, there is a fundamental challenge to any leak testing method, whether it is a fish tank-bubble, vacuum deferential, or helium test: none of these methods detect non-leaking seal defects.

Pressure Decay

Various applications like plastic bottles and containers food, beverage and pharmaceutical industries require online leak detection of empty containers before filling and sealing process. Leak testing is also an essential step to assure complete container integrity.

Force Decay

The VeriPac 410 inspection technology platform combines the sensitivity and reliability of PTI’s vacuum decay technology while introducing a force-based measurement to enhance results. The 410’s force decay technology is capable of measuring force from the surface deflection of a package during a normal vacuum based test cycle.
