Laboratory glassware. Single-volume pipettes1 Scope This International Standard specifies metrological and constructional requirements for volumetric pipettes with one mark (total delivery) and for volumetric pipettes with two marks, both of which are adequate for general laboratory purposes. The details specified are in conformity with the principles of design and construction of volumetric glassware given in ISO 384. NOTE For graduated pipettes, see ISO 835. For piston operated pipettes, see
