For Clients: Submissions

The Center for Environmental Sciences and Engineering (CESE) at the University of Connecticut is a full-service research and analytical chemistry facility, supporting the needs of academic, government, commercial, and non-profit organizations.

CESE Environmental Chemistry Laboratories benefit from a comprehensive capacity to conduct physical and chemical analyses of bioactive compounds including cannabinoids and persistent or nontraditional environmental pollutants in biological tissues, surface and ground waters, sediments, soils, and hazardous waste. The state-of-the-art laboratories are staffed by experienced professionals that provide timely analytical results of a high quality, under the umbrella of a comprehensive quality management system, certified by the State of Connecticut Department of Public Health.

How It Works

How to Submit Samples

There are several options for transporting your samples to the lab for testing. Clients can physically bring samples to the lab on the UConn Storrs campus or send them via courier using next-day service (UPS or FedEx) to: 3107 Horsebarn Hill Rd, Unit 4210, Storrs, CT 06269

To ensure sample integrity, store samples in a cooler with ice packs until they are delivered to the lab. All samples shipped to the laboratory should be frozen prior to shipment or shipped in a cooler with ice packs.
Regardless of the method you choose, all samples must be accompanied by a completed chain of custody (CoC) form . This form contains spaces for the client to provide the required information to correctly handle and process your samples. Required information includes sample identification; location, date, and time of collection; preservation type; required turnaround time; sample matrix; and analytical tests. The labs may not accept sample submissions with incomplete CoCs. Please contact the laboratories with any questions on how to fill out the CoC.
