Since receiving accreditation in 1999, our goal is to be the first choice in microbiological proficiency testing. Our dedicated staff of experienced microbiologists are the perfect team to administrate PT studies and manufacture microbiological standards for drinking water.
Analysts prefer full volume standards because they best simulate typical drinking water samples.
We ship our ColiPT sets FedEx overnight for Tuesday arrival. The due date for test results is 2 weeks later at which time that study is closed. The day after a study closes, the True Values are posted to our website. Click here to view the current True Values. Every participant receives a personal Test Results Report .
