摘要： 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).
