The shelf life can only be guaranteed for sealed and adequately stored items. The storage conditions can also be found in the operating instructions in the section "Technical data".
The exact expiry date is indicated on the product label in the following format: YYYY-MM-DD, where the exact expiry date is always the 28th of the month. This format follows FDA recommendations for the Unique Device Identification (UDI) system.
The shelf life of 8 years of our epQuality™ Consumables relates to the technical material properties of our products. The limited shelf life of 5 years for the higher purity grades (e.g., sterility) refers to the products’ purity, as it may be more strongly influenced by packaging and storage conditions than the material properties.
