SRI’s high-quality equipment is used worldwide for biotechnological processes such as medicine and vaccine production. Equipment requirements in the biotechnology industry are extremely strict, even exceeding those in the pharmaceutical chemistry industry. For reasons of cleanability and optimal drainability, our customers generally demand electropolished interior finishes. Most equipment we manufacture features a cooling and/or heating mantle as well as a welded insulation housing. Due to our designs all connections are guaranteed leak free. Usually, our customers opt for high-gloss polished exterior finishes – as for bioreactors, they are often set up in a separate cleanroom.
