Quality Assurance System and Product Management

Based on dispenser technology that has been cultivated since our establishment in 1944, the history of Nichiryo's pipettes started from the first micropipette "Justor" launched in 1975, and now it keeps evolving further as "Nichipet series" under ISO9001-based quality assurance system in addition to considerable technological and sales experiences.

IVDD (98/79/ec) Directive Obtained For In Vitro Diagnostic Devices

IVDs (in vitro diagnostic medical devices) comply with EU Directive 98/79/EC. IVDs are a subgroup of medical products whose market access, specifications, and market oversight are under regulatory control. Our pipettes have been self-declared as a CE-marking IVD device and are manufactured and sold in accordance with the requirements of the European Union under appropriate control. If pipettes are used at medical facilities in the EU or for medical purposes (including accessories) in the EU, products with a CE mark on the pipette must be used. In addition, as a recent trend, Asian countries are increasingly requiring CE marking of pipettes in accordance with the requirements for CE marking, and this is becoming a global standard.
