Potomac is a leader in laser drilling of calibrated holes for leak testing applications.
Potomac is able to laser drill micro-holes into glass and polymer vials/ampules for the purpose of leak test hole system validation. A range of hole sizes can be created in order to replicate defects in vials for use when calibrating leak detection devices. Depending upon the wall thickness of the vial/ampule, hole sizes can be as small as 1µm. In addition to vials, foil and blister packs can also be laser drilled. Potomac Photonics is ISO 13485 certified and we have drilled hundred of thousands of packages for the pharmaceutical, food and medical industries.
Leak testing or Container Closure Integrity Testing (CCIT) is an assay that evaluates the adequacy of container closure systems to maintain a sterile barrier against potential contaminants. Contaminants that could potentially cross a container closure barrier include microorganisms, reactive gases, and other substances (USP <1207>). Container closure systems should maintain the sterility and product quality of sterile final pharmaceutical, biological, and vaccine products throughout their shelf-life (Ewan, S. et al., 2015).
Container closure systems consist of primary packaging components and secondary packaging components (USP <1207>). Primary packaging components are those components that come into direct contact with the product, such as a glass vial or syringe. While, secondary packaging components are those components that are vital to ensure correct package assembly, such as aluminum caps over stoppers (USP <1207>). (Source: America Pharmaceutical Review)
