Laser coding system for glass syringes

An innovative laser-coding system enables glass containers for parenteral use to be clearly coded at the glass syringe manufacturer and tracked from production to customer.

The process was developed and tested under production conditions by a team of experts from Roche Diagnostics, Schott forma vitrum, Schott-Rohrglas, Seidenader Vision and Vesdo. The proof of concept for large-scale production is now available and the process ready for implementation

An innovative laser-coding system enables glass containers for parenteral use to be clearly coded at the glass syringe manufacturer and tracked from production to customer.

The laser-coded containers meet cleanroom standards and no additional chemicals or materials are required for coding. The laser-coding system can also be integrated into existing filling systems.

The process was developed and tested under production conditions by a team of experts from Roche Diagnostics, Schott forma vitrum, Schott-Rohrglas, Seidenader Vision and Vesdo. The proof of concept for large-scale production is now available and the process ready for implementation.

Various tests have shown that the laser coding causes no micro-cracks and has no effect on the mechanical stability of the glass, says Schott. The process can safely code each container with an individual 2D data matrix code, making it 100% readable. To guarantee readability of the code on the curved glass surface of the syringe, the team has developed dedicated algorithms and test methods.

The laser-coding concept also offers a documentation tool that can provide a trail for each container including information such as: place of production, fill date, expiration date or day of use. The code is tiny - only 2x2mm. The 2D data matrix code allows for the indexing of a database record containing data related to the individual item, such as drug specification, dosage, production line and batch. This record can have more data added during the lifecycle of the product.

The process can be used for syringes as well as vials, cartridges and ampoules.
