All of the qualification solutions start with a 2 year expiration date from the time they were made and we have validated data to support this expiration. The date of manufacture and the expiration date are both printed on the COA provided with the product.
You can use these solutions with full confidence right up to the expiration date given and beyond if your SOP allows it. If you require a longer expiration date than what is shipped to you, it can be prepared as a custom made item but the lead time is about 6-8 weeks. MicroSolv will ship no less than six months before an expiration date as a matter of routine as most customers consume these solutions in less time.
