Industrial Hygiene Laboratory Chain of Custody (CoC) Forms

Ensuring the integrity and traceability of every sample entrusted to us is paramount, and our CoC forms are a key part of that commitment. Our CoC forms are standard forms designed to capture vital information about each sample, including its origin, handling instructions, and any specific client requirements. By completing these forms accurately and comprehensively, you not only help streamline the processing of your samples but also contribute to the integrity of the entire testing process.

We encourage you to provide advanced notice of your projects and sample shipments. By doing so, you enable us to allocate resources effectively, minimize turnaround times, and deliver results that meet your expectations.

Thank you for choosing us as your partner.
