CPI International recognizes the growing importance of solid phase extraction, and we offer a wide range of SPE products to meet even the most specialized need. Among these products are our own patent-pending disks for single-phase and our patented multiple-phase disks. These disks solve several technical problems that have plagued SPE for years, will run samples that no other SPE product is capable of and cost less than competing disks. That’s one example of the innovation and value you’ll discover in our complete range of SPE supplies.
