Abstract: A pipette tip includes a main body having an upper end, a lower end and a sidewall extending between the two ends. A bore extends axially through the main body between the upper and lower ends. The lower end has a bottom surface in which is formed a central opening that communicates with the axial bore to allow the passage of fluid therethrough. The bottom surface is formed with at least one groove that may be concentrically disposed or spirally disposed about the central opening. The at least one groove acts to inhibit fluid passing through the central opening from at least partially flowing along the outer surface of the sidewall from the central opening toward the upper end of the main body of the pipette tip.

Abstract translation: 移液管尖端包括具有上端，下端和在两端之间延伸的侧壁的主体。 孔在上端和下端之间轴向延伸通过主体。 下端具有底表面，其中形成有与轴向孔连通以允许流体通过的中心开口。 底表面形成有至少一个凹槽，其可以围绕中心开口同心地设置或螺旋地设置。 所述至少一个凹槽用于阻止流经中心开口的流体至少部分地沿着侧壁的外表面从中心开口朝向移液管尖端主体的上端流动。
