PTI Inspection Systems PTI is a global leader in package testing equipment for the medical device and pharmaceutical industries.  We offer inspection systems for package leak testing, seal integrity and container closure integrity testing (CCIT). Our technologies exclude subjectivity from package testing, and use test methods that conform to ASTM standards. PTI’s inspection technologies are deterministic quantitative test methods.  We specialize in testing solutions for porous and non-porous pouches, Tyvek packaging, Tyvek pouches and Tyvek lidded trays.  PTI offers the entire solution including test method development and equipment validation.

PTI offers two primary technologies to inspect medical device packaging; vacuum decay and airborne ultrasound.  Both technologies aim to offer quantitative and deterministic test results to evaluate package quality.  The two technologies are vastly different in function and performance.  Vacuum decay is focused on package integrity and detection of leak paths.  Airborne ultrasound is focused on seal inspection and seal quality.  Contact us to learn more.

Tyvek® gives the premium microbial barrier protection for sterilized medical instruments and pharmaceuticals. Apart from protecting the medical devices and pharmaceutical products from physical damages, medical and pharmaceutical packages also should provide an effective microbial barrier and help to maintain the sterility of the products. Bacteria and viruses with sizes varying from 0.002 to 100 microns are a constant threat to pharmaceuticals and medical devices which in turn can be hazardous to the patients.

PTI's Seal-Scan® and Seal-Sensor® are non-contact airborne ultrasonic testing technologies.  In order to use ultrasonic inspection effectively, it must be possible to place the seal in a direct line between a pair of transducers and move it (or move the transducers) along the seal. The ultrasound is transmitted and reflected at the transition from one media to the next. The greater the acoustic difference between mediums (most evident at a gas to solid transition) the more sound is reflected and the less sound transmitted through. The variation of the material thickness has only a minor effect.

Class III medical devices have a unique set of requirements and package characteristics that need a comprehensive approach to selecting the right inspection method.Advanced approaches for quality assurance of these leading-edge treatments may be needed for a variety of reasons.

PTI has developed a new standard for protecting, storing and presenting data generated from its line of non-destructive leak testers in the form of a software package called PTI Ethos.

VeriPac FLEX Systems are versatile non-destructive package inspection systems designed for pouches and other flexible packaging.

VeriPac 355 is a non-destructive micro leak detection system for container closure integrity and package integrity testing for a wide range of products and packaging formats. This system is specifically designed to test containers for gas leaks for dry products (lyophilized vials, powder filled) as well test for liquid leaks (non-protein based liquid filled vials, prefilled syringes). The VeriPac 355 can be incorporated into protocols at any point in the handling process as it is non-destructive and requires no sample preparation. With the capability to detect leak rates as low as 0.2 cc/min, depending on packaging specifications, the VeriPac 355 is the optimal non-destructive quantitative test method for many pharmaceutical and food applications.

Seal-Scan® is an Airborne Ultrasonic Technology (ABUS) that inspects and analyzes pouch seals non-destructively offline.  Seal-Scan® is a deterministic, quantitative, high resolution method that inspects pouch seals for defects and seal integrity for consistency.  Testing is non-destructive, non-invasive, and requires no sample preparation. Seal-Scan® provides advanced digital imaging software tools for process control which offers in-depth seal quality analysis.

The VeriPac 410 utilizes a combination of vacuum decay technology and differential force measurement to identify defective packages. Multiple packages can be tested in a single test cycle, and the 410 identifies which package or cavity is defective. 

Complementing the high cost of medical device manufacturing, there is a high value placed on the sterility and quality of the final product which are the main reasons for successful integration of Seal-Scan® airborne ultrasound seal inspection for medical device packaging.
