HHAC Labor Dr. Heusler
Your GMP contract laboratory

HHAC Labor Dr. Heusler was founded in 1992 in Stutensee near Karlsruhe as an independent service laboratory. Since then, the laboratory has been able to establish itself as a constant player in the field of chemical-physical analysis for the pharmaceutical industry. In step with our entrepreneurial growth, our range of services has also expanded over the past three decades.

Today, it ranges from release testing and stability testing to method development, validation and transfer as well as GMP consulting and includes synthetic APIs as well as herbal active pharmaceutical ingredients in solid, semi-solid and liquid preparations. As an external laboratory for the testing of medicinal products, we are of course registered in accordance with §67.1 AMG, hold a manufacturing license for human and veterinary medicinal products and are inspected by our competent authority on a regular basis.
