Since we opened our doors in 1987, our commitment to accurate analytical reporting and unequalled customer service has set the foundation for our continued growth. Over the years, our philosophy has remained the same: provide superior customer service, take care of our employees, and respect our environment.

Pat Chem Laboratories (PCL) uses the latest laboratory information management software (LIMS) to track every sample. At any time, we can tell you exactly where your sample is in the testing process. With PCL Web Connect, our customers have 24/7 access to their reports via secure access with unique logins. Our high-tech lab is equipped with the most advanced technology in the industry and the expansive sample receiving and storage area can handle projects of any size.

The majority of our client base is in California, but we provide analytical services to companies throughout the USA, and even overseas.
