Inspection station for examining sterility test, media fill trials or for visible particles in
filled vials, ampoules or Prefilled Syringes
(PFS)
Apparatus1
- Vertical matte black panel
- Vertical non-glare white panel next to black
panel
- Adjustable lamp holder with shaded, white
“daylight” source and …a diffuser (…two 13W
fluorescent tubes, each 525 mm (20.7 in) in length
is suitable). …illumination at the viewing point is
…between 2,000 and 3,750 lux for clear glass ampoules or vials. Higher values are preferable for
coloured glass and plastic containers.
- under a maintenance plan to check lux. (Note lamp output can drop 50% in 12months)
Recommended procedure
- Gently swirl or invert each individual container, making sure that no air bubbles are introduced, and
observe for about 5 seconds in front of the white panel. Repeat …in front of the black panel.
- Record the presence of any particles or in the case of sterility testing or media fill trials, any
turbidity. Repeat the procedure for all containers.
