Over 35 years of experience
Founded in 1989, Constant Systems Limited is now well into its fourth decade of operations and is still very much dedicated to the design, manufacturing and maintenance of high-pressure cell disruption equipment, which has built a reputation on reliability, reproducibility, efficacy, and consistency.
