A pipet for transferring fluids of the present invention includes a distal tip, a barrel portion with an exterior surface, and a proximal neck. The pipet has a hollow bore. There are graduation markings on the exterior surface of the barrel portion for determining a volume of a fluid contained in the pipet. The graduation markings have a longitudinal and a radial orientation about the barrel. The pipet of the invention further includes a proximal mark for indicating the radial orientation of the graduation markings on the barrel that allows an operator to mount the pipet in a pipetter with the packaging open only at the neck end of the pipet in the most favorable orientation for use. |
