Abstract
A duplex pipette comprises a housing, a pair of cylinders separately formed in the housing to extend substantially in parallel to each other, first and second piston members each having a lower end portion slidably received in one of the cylinders and a handle portion projecting outside the cylinder, and a pair of pipette tips mounted on the lower end of the housing by way of a connecting member, each of the pipette tips having a passage which communicates one of the cylinders with the outside of the housing. The connecting member is arranged so that the distance between the distal ends of the pipette tips can be changed. One of the piston members is arranged to be movable separately from the other piston member and the other piston member is arranged to be movable only together with said one piston member.
