Our Continuous Flow Centrifuge (CFC) utilizes an innovative centrifugation technology that is EPA-approved for the concentration of Cryptosporidium from surface water samples and, is particularly effective with highly turbid water. In November 2004, our CFC received an EPA Tier 2 approval, making it available to all laboratories that provide Cryptosporidium testing under the Long-Term 2 Enhanced Surface

Water Treatment Rule.
