VDS Optilab has been manufacturing HPLC columns in all common and special sizes and with almost all available separation phases since 1987. The high quality of its products has impressed customers in the fields of research and development and quality control, from universities and regulatory agencies to large groups in the chemical and pharmaceutical industry. The merger with Muder & Wochele GmbH in 2002 enabled both customers and companies to benefit from the know-how and expertise of both companies.
