TMBS

High Quality Biological Supplies for Engaging Science Education, Empowering educators and researchers with live specimens, preserved materials, and custom lab kits delivered with precision and care.

Trans-Mississippi Biological Supply (TMBS) began in 1936 with a simple yet powerful mission: to bring high-quality biological supplies into the hands of educators and researchers. Over the years, we’ve evolved and grown, but one thing has remained constant—our passion for inspiring the next generation of scientists. When our current owner took the helm, they brought with them decades of experience and a heartfelt dedication to education. Today, TMBS is proud to serve schools, universities, research institutions, and STEM programs nationwide, helping them deliver hands-on science experiences that spark curiosity and foster understanding.
