AI Technical Summary

Technical Problem

Conventional inspection booths struggle to reliably inspect liquid biological products with low fill volumes due to the meniscus creating a blind volume, obstructing the view of particles suspended in the fluid.

Method used

A method and assembly that orient the container upright and utilize a line-of-sight redirection member, such as a mirror or beam splitter, positioned below the container to direct the inspector's view through the bottom wall, combined with polarizers and illumination, allowing inspection of the container's interior.

Benefits of technology

Enables effective inspection of particles in liquid biological products by overcoming the obstruction caused by the meniscus, ensuring comprehensive visibility and reliability in identifying defects.
