Checkweighers improve Sanofi-Aventis productivity

Sanofi-Aventis is the global leader in core medical areas. 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 from METTLER TOLEDO. The XS2 checkweigher separates packages with missing or empty vials at very high line speeds. The smallest vial has a net capacity of just 1 ml with a fill weight of 1 gram. 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 grams.

Gliding limits are based on the nominal weight of the pharmaceutical products


As the weight of all the individual package components can vary from batch to batch, the "gliding limits" function is used to take these fluctuations in weight into account by defining variable upper and lower limits. This enables medium and long-term fluctuations against the mean value to be recorded and remedied. Long-term tare fluctuations can therefore be compensated using these newly calculated tolerance limits. The removal of the defective products under the "gliding limits" option is based solely on the nominal weight of the pharmaceutical product.

Optional automatic IPC check (in-process check)

The METTLER TOLEDO checkweigher also supports the IPC check required in the pharmaceutical industry. Quality control spot-checks must be performed on a regular basis for documentation reasons. These "spotcheck products" are sorted by the checkweigher at the touch of a button. Extensive product tracking between the checkweigher's infeed and outfeed conveyors is an X-Series standard feature. This allows the active, continuous tracking of products which is required in the pharmaceutical industry.

"Process reliability plays an extremely important role in the production of pharmaceutical products. Our medicines save lives. Insulin is a vital substance and market demand must be met. It is essential, therefore, that the availability of our products is always guaranteed", says Stephan Koll, responsible for production in the Injectables Division. "We opted for the METTLER TOLEDO checkweigher because it meets our standard component requirements in full" continues Koll.

Through the use of many standard components, METTLER TOLEDO can always guarantee the availability of spare parts for enhanced productivity. Furthermore, the stringent service demands of a modern and critical pharmaceutical company are fulfilled thanks to the efficient METTLER TOLEDO service network.
