Pyrex® Class A Cylinders

Pyrex^® Class A cylinders are printed with a Trace Code so that the item can be traced back to the point of production.

With this service you can quickly and easily use the Trace Code to call up a batch certificate that gives the date of production and compliance with ISO4788.

Simply key in the batch number found on the product. The batch number is located at the top of the cylinder for example 241.12 or 13.01.
