Type II-N pipettes, which are adjusted for delivery of a liquid from any graduation line down to the jet, where the nominal capacity is represented by the highest graduation line.
Type III-N and Type III-W pipettes, which are adjusted for delivery of a liquid from the zero line at the top to any graduation line, where the nominal capacity is obtained by delivery down to the jet.
Two classes of accuracy are specified, Class A pipettes being of higher accuracy than Class B pipettes. Type III-N pipettes are only Class B while Type III-W pipettes are only Class A.
