Our Services

Perritt Laboratories is an ISO/IEC 17025–accredited, cGMP-compliant testing laboratory specializing in child-resistant packaging evaluations and microbiological testing for regulated industries. As a specialized contract testing lab, we help pharmaceutical, consumer product, and packaging companies deliver safer, compliant products backed by scientifically rigorous data.

Once testing is complete, we deliver a detailed, defensible report that provides the technical documentation required for successful regulatory submission.

Child-Resistant Package Testing

We evaluate packaging performance under real-world conditions and strict procedural control to verify that designs are child-resistant while maintaining accessibility for adult users.

Microbiological Testing

Beyond packaging, our microbiology division provides comprehensive testing aligned with USP, EP, and JP compendial methods.

Precision Testing Backed by Over 50 Years of Expertise

Since 1973, we have played a defining role in the development and evolution of U.S. child-resistant testing standards. Our team has decades of hands-on experience with global regulatory requirements, including CPSC 16 CFR 1700, EPA 40 CFR 162, ISO 8317, EN 14375, and CSA Z76 standards. This deep historical knowledge allows us to guide clients through complex compliance challenges with clarity, accuracy, and confidence. From raw materials and in-process samples to finished goods and environmental monitoring, our scientists deliver precise, dependable results that stand up to audit scrutiny.

Industries Served

We provide microbiological & child-resistant packaging testing services to a wide range of customers, from start-up & virtual companies to some of the largest names in the pharmaceutical industry.
