What Are Extractables and Leachables?
Extractable and Leachable (E&L) testing is critical for ensuring the safety of pharmaceutical products, packaging, and medical devices. Extractables are compounds that can be extracted from a material under extreme conditions, while leachables are those compounds that migrate into the product under normal usage conditions. At ResolveMass Laboratories, we offer comprehensive E&L testing to ensure regulatory compliance and safeguard patient health.
