Our Story

When our founder Dr. David Levowitz was with the Dairy Manufactures Department of Rutgers University, NJ, he saw the need for an agency which would promote quality in dairy & food production.  In 1936, he established New Jersey Dairy Laboratories for that purpose.  As our lab grew so too did our reputation for quality as we gained recognition across the country for being ahead our time and unique in pioneering carefully standardized analytical testing methods & control systems.  In the late 70s, our new owners dropped “Dairy” from our name as we began to offer pharmaceutical, environmental & water testing services.  Then in 1989, we moved to our current location in New Brunswick, NJ.

Quality — the essential element in analytical testing since 1936

Today, NJ Labs specializes in analytical chemistry and microbiology testing for the pharmaceutical, nutraceutical, dietary supplement, cosmetic, dairy & food industries.  Our privately-owned FDA & DEA inspected; certified full-service contract analytical testing laboratory continues its mandate of following strict CGMP regulations.  Our team of scientists also continue to build upon a legacy of developing and validating methods for raw materials and finished products established by our founder over 80 years ago.

So, if you are looking for an analytical testing lab whose essential element is quality:

Message from Our CEO

As the CEO of NJ Labs, I am thrilled to be part of a cutting-edge, highly competitive industry that is constantly evolving. Not only do new technologies advance at incredible rates, but the science itself is continually in flux. Just when you think that steady ground has been reached, a new breakthrough technology or medication emerges that overturns prior assumptions. The caveat here is that in this kind of environment, the need to stay competitive and reduce cost is often prioritized at the expense of quality with the end consumer often being forgotten.

At NJ Labs, our clients will always be our priority and compromising on quality is not an option. I strongly believe compromising on quality puts both our clients and ultimately the end consumer at risk. To help our clients remain innovative and competitive while meeting rigorous compliance requirements, we have continued to grow our expertise and to develop quality systems grounded in transparency, integrity, and honesty.

For example, over the past several years, we have completed major improvements to our facilities and laboratory equipment. We have also grown our staff by over 100 percent to accommodate stringent testing criteria. And we have rigorously trained all our employees on our extensive instrument inventory. We also routinely collaborate with manufacturers to stay ahead of the information and technology curve. We have developed an extensive library of internal Standard Operating Procedures (SOPs) and continue to expand our test capabilities and methodologies in analytical chemistry and microbiology.

Most recently, we have delved into the uncharted territory of CBD, cannabis, and hemp testing; taking on the challenge of using complex instrumentation to validate and analyze samples for heavy metals, potency, microbiology, and toxins in a CGMP facility. NJ Labs will continue to pursue the potential of this growing industry.

For over eighty years, we have continued to grow with our clients to meet their research and development needs while addressing the aggressive increase in demands from regulatory bodies. We are prepared and excited to be a part of our clients’ growth and progression as we continue into the 21st century.
