Pioneering Excellence in Decalcification

For over five decades, Apex Engineering Products Corporation has been the trusted name in rapid decalcification solutions for laboratories worldwide.

Our Story

Founded in 1966 in Illinois, Apex Engineering Products Corporation began with a simple mission: to develop superior decalcification solutions that save laboratories time without compromising specimen quality.

Our founder recognized that traditional decalcification methods were slow and often damaging to delicate tissue structures. Through years of research and development, we created RDO—an innovative formula that decalcifies bone and tooth specimens in hours rather than days.

Today, RDO is trusted by thousands of histology laboratories, medical schools, research institutions, and forensic facilities around the world. Our commitment to quality and innovation remains as strong as ever.
