Abstract: An apparatus (10) for dispensing liquid in conjunction with an array of pipette tips (14), where each pipette tip (36) includes a socket portion (42). The liquid dispensing apparatus (10) includes tubes (25), each including a barrel (28) and a lower end (33), and a nozzle (34), each nozzle (34) having a shoulder (68) and a mouth (44) configured of appropriate diameter to enter into the socket portion (42) of each pipette tip (36), and form a liquid-tight seal therewith. A bottom plate (24) includes a number of through-holes (72) through which each of the nozzles passes (34). The through holes (72) are of larger diameter than the nozzles (34) so that limited lateral movement is allowed. A second embodiment (100) is convertible, so that separation of upper (73) and lower boundaries (75) may be decreased such that the upper boundary (73) contacts the shoulders (68) of said nozzles (34), to hold the nozzles (34) in fixed position, for use with pipette tip arrays (96) which are not bound together in fixed spatial relation to each other, but which are themselves allowed limited lateral movement. Both embodiments (10, 100) may further include a shucker plate (50) such that when the shucker plate (50) is made to travel away from the bottom plate (24) by an ejection mechanism (85), the pipette tips (36, 97) are pushed off of the nozzle mouths (44).

Abstract translation: 一种用于与一系列移液管尖端（14）一起分配液体的装置（10），其中每个移液管尖端（36）包括一个插座部分（42）。 该液体分配装置10包括管25和喷嘴34，每个管包括一个筒体28和一个下端33，每个喷嘴34具有一个肩部68和一个嘴部 44）具有适当的直径以进入每个移液管尖端（36）的插座部分（42），并与其形成液密密封。 底板（24）包括多个通孔（72），每个喷嘴通过该通孔（34）。 通孔（72）的直径大于喷嘴（34）的直径，从而允许有限的横向运动。 第二实施例（100）是可变换的，使得上部（73）和下部边界（75）的分离可以减小，使得上部边界（73）接触所述喷嘴（34）的肩部（68），以保持 与固定位置的喷嘴（34）一起使用，用于与移液管尖端阵列（96）一起使用，这些移液器尖端阵列不以彼此固定的空间关系结合在一起，而是本身允许有限的横向移动。 两个实施例（10,100）还可包括折板（50），使得当通过弹出机构（85）使折板（50）远离底板（24）行进时，移液管尖端（36 ，97）被推出喷嘴口（44）。
