Onion Skin Ampoule Filling and Sealing

A manufacturer of drug and explosive detection equipment for law enforcement, hazmat teams and educational systems.

Cozzoli were approached about a need for filling onion skin style ampoules. These ampoules would be part of a mobile detection system, where after swabbing a potentially contaminated area, the swab is inserted into the pouch and the ampoules are crushed. The chemical inside of the ampoule mixes with the swab and will detect if any drug or explosive residue is present.

This application would require the ampoule to be filled with a small and very precise amount of liquid, then flame sealed.

This was a perfect application for our FPS series ampoule filling and sealing MonoBlock. The application required the filling of 6.70mm x 60mm onion skin tubes with .10 mL -.40 mL of liquid. This would have to be done at a production rate of 45 -50 ampoules per minute. Due to these requirements, the FPS1-OS-SS was chosen for the job.

Our FPS series monoblock fills and seals a variety of ampoule shapes and sizes, at speeds of 15-120 ampoules per minute and a fill accuracy of +/- .5%.

With the fill volume requirements being so small, a peristaltic pump was added in order to feed the liquid into the machine. A peristaltic pump is typically used for very precise filling applications, as well as applications where the liquid is clean/sterile and cannot come into contact with any exposed pump components.
