Bioengineering AG's headquarters are based out of Wald, Switzerland since 1972 and the North American subsidiary is located in Pasadena, California. We manufacture bioreactor and fermenter systems from 2L bench scale glass, to pilot, to full production plants, with vessel volumes of up to 150,000 L in stainless steel. These are all manufactured under the same Swiss quality and attention to detail you've come to expect from Swiss engineered products for over 50 years.
