It goes without saying that GEISSLER is certified according to DIN EN ISO 9001 : 2015. Furthermore, only certified companies are approved as suppliers. Both our products and our production methods are subject to constant control. Great emphasis is placed on occupational safety and environmental compatibility. The imprint of batch numbers ensures the traceability of each ampoule back to the raw glass.
Forward and backward traceability down to the individual component is standard practice for our products.
