Inspection targets closure integrity between the rubber stopper and aluminum crimp seal.

Inspection focuses on microleaks or pinholes along fused edges and vent channels of each cavity.

Leak testing focuses on detecting microcracks and incomplete tip seals in the fused glass area.

Leak testing evaluates sealing at the rubber stopper and crimp interface to ensure containment.

Integrity testing emphasizes welded ports, seams, and heat-sealed edges where leaks may occur.

Leak detection focuses on cap seal tightness and bottle neck closure performance.

Inspection checks for leakage through the plunger seal, needle hub, and tip cap junctions.

CCIT verifies vacuum retention and stopper compression following lyophilization and crimp sealing.

Testing ensures seal integrity at the nozzle and cap interface under pressure or vacuum stress.
