Empty bottle inspection equipment can help ensure the safety and quality of a bottle-filling operation. Bottles may need to be inspected for variation in size, shape, and color, for the presence of foreign objects, for breakage, or for the presence of residual liquid. The bottle finish, capping-thread, inner and outer sidewalls, may also require an inspection to ensure compliance with quality standards. Considerations for selecting the right equipment include the size, shape, and material of the bottles, production speed, and other relevant inspection parameters. Bottle inspection equipment is widely used in the food industry to ensure compliance with quality control procedures. In the pharmaceutical industry vial, ampoules and bottles are inspected to ensure product safety.
