Pharmaceutical Manufacturer Utilizes Checkweighers To Identify Inaccurately Filled Product

Sanofi Aventis

In no other industry is the need for product quality and process reliability as critical as in the pharmaceutical industry. Sanofi-Aventis is the global leader in core medical areas, such as diabetes/metabolism, the cardiovascular system, thrombosis, the central nervous system, internal medicine, oncology and prevention through progressive vaccines. METTLER TOLEDO checkweighers check vital insulin: in the Injectables Division, where liquid drugs such as different types of insulin or drugs for emergency medicine are produced, the packaged medical compounds are subjected to final checks using a dynamic checkweigher.

The in-line checkweigher separates packages with missing or empty vials. The smallest vial has a net capacity of just 1 ml with a fill weight of just 1 g. Over 20 different drugs in a variety of package sizes are packed on this production line with a throughput of up to 400 packages per minute with an accuracy of 0.3 g. Defective product packages which have been under or overfilled, as well as packages that are not correctly aligned i.e. askew, are sorted by two separate air jets into separate collection containers.
