DUCHEFA Biochemie B.V. was founded in 1989 as a sister company of our first company, DUCHEFA Farma B.V., which has been selling pharmaceutical raw materials, chemicals and additives to dispensing pharmacists, hospitals and wholesalers, since 1968. These products are used for the preparation of medicines for human use, so therefore the quality level maintained by our company must meet the highest (G.M.P.-) standards. Sensitive to the wishes of a growing population of customers, DUCHEFA started to attract customers from other, non-pharmaceutical based markets.
Because of this, the foundation of DUCHEFA Biochemie B.V. was a logical step in developing our business to new levels, and a special supply program for in vitro plant tissue and cell culture laboratories was set up. As it was founded in a country with a long-standing history in agriculture and growing of flowers as well as international trade, it goes without saying that DUCHEFA Biochemie B.V. specialises in chemicals and media used in plant biotechnology. Now, some decades later, these and many new products find a world-wide application and are used in leading institutes within universities, as well as plant cell- and tissue laboratories alike.
Our product range is mainly composed of media, growth regulators, antibiotics, gelling agents, substrates, and chemicals for plant molecular biology and seed health testing. Today's general catalogue comprises of more than 180 full-colour pages in which over 400 products used in plant biotechnology are presented. These pages are livened with some 100 full-colour pictures, provided with kind permission by customers from all over the world, among who are many renowned laboratories. The catalogue also contains a product range for phytopathological usage, comprising of more than 20 media for testing pathogens on seeds of various crops. In 2006, Prepared Plates ready to use were added to this range of media. These Petri dishes are available with all presented phytopathology media.
