PennTech offers a uniquely simple, yet effective, method of loading pharmaceutical vials into the depyrogenation tunnel. The key here is to keep positive control over the vials at all times.
Unlike “reverse funnels” and timing screws, vials are collected from the vial washer into a “pack” before gently being pushed into the tunnel by an oscillating pushing block.
No format parts are required and the pushing motion is part of the vial recipe in the PLC. This is essentially a set-it-and-forget-it automatic process requiring no operator intervention.
Automatic Gate Height Setting: The three chambers of the tunnel are separated by gates. The height is automatically set by the PLC as part of the vial recipe.
DOP Testing: HEPA filters are tested for efficiency by the “DOP” test procedure. Each chamber of the tunnel has provisions to conduct the DOP test.
Particle Counting: Each chamber is equipped with a pipe below the filters to allow for particle counting
