Abstract: The pipetting method is directed to mounting and ejecting a disposable pipette tip. The pipetting system has one or more tip mounting shafts with an upper locking section and a lower sealing section. The upper locking section has outwardly extending lobes spaced around the mounting shaft and located above a stop member. The lower sealing section on the tip mounting shaft is located below the stop. As the mounting shaft is inserted into the collar of the disposable pipette, the collar distorts out of round and engages the lobes on the upper locking section of the tip mounting shaft. Contemporaneously, the lower sealing section of the mounting shaft seals against the barrel of the disposable pipette tip.

Abstract: In one aspect, the invention relates to a pipette tip mounting shaft configuration and a disposable pipette tip having a matching configuration. The mounting shaft includes a locking section located above a lower sealing section. The locking section has outwardly extending locking lobes located above a stop member and a lower sealing section located below the stop member. In certain embodiments, the diameter of the mounting shaft below the stop member is reduced in order to lessen insertion and ejection forces, which is particularly helpful for hand-held multi-channel pipettors. In these embodiments, the lower sealing section contains either a frustoconical sealing section, or an annular groove and a sealing ring, such as a flouroelastomeric O-ring seal. When the mounting shaft is fully inserted into the collar of the mating disposable pipette tip, the tip locks onto the mounting shaft. The bore of the pipette tip includes a circumferential shelf or shoulder separating its upper collar from the tip sealing area which is located below the circumferential shelf. The tip collar preferably includes a locking ring located at or near the upper opening for the mounting shaft. The dimensions of the collar, and in particular the distance between its circumferential shelf and the locking ring, are selected to match the dimensions of the mounting shaft between the stop member and the upper end of the locking lobes, thus locking the pipette tip in a secure, reliable position and orientation while using ergonomic insertion and ejection forces. The locking lobes preferably include a ramp portion that gently flexes and distorts the pipette tip collar out of round as the mounting shaft is inserted in the pipette tip, rather than stretching the tip collar. The circumferential shelf on the pipette tip between the tip collar and the barrel isolates the sealing area at the upper end of the barrel from distortion, thus facilitating reliable sealing engagement between the lower sealing section of the mounting shaft and the sealing ring in the upper end of the barrel of the pipette tip.

Abstract: A pipette tip mounting shaft includes outwardly circumferentially extending locking lobes over which the pipette tip collar is mounted. The locking lobes preferably include an inclining ramp portion that gently flexes and distorts the pipette tip collar out-of-round as the mounting shaft is inserted into the pipette tip, rather than the stretching tip collar. Each locking lobe also includes a declining ramp portion which extends upward along the mounting shaft. The peak of the lobes is preferably curved. When the pipette tip is fully mounted on the mounting shaft, a locking ring on the inside surface of the tip collar engages the declining ramp of the lobes to provide an over-center engagement, however, the required ejection force is small.

Abstract: A liquid sample or liquid reagent reservoir kit employs a reusable reservoir base and disposable liners made of a clear transparent plastic material. Graduation marks are located on the sidewall surface of the basin in the reusable reservoir base, and are calibrated to measure liquid volumes in a disposable liner placed within the reusable reservoir base. The transparency of the clear disposable liner allows the liquid volume graduation marks on the sidewall of the basin in the reusable base to be observed through the disposable liner. The disposable liners are configured so that the liners can also be used as a cover. The geometry of the disposable liners facilitates tight nesting of stacked liners to facilitate shipping as well as storage on the laboratory bench top.

Abstract: A disposable pipette tip having that is configured to mount on a tip mounting shaft having a locking section and a separate sealing section. The locking section has outwardly extending locking lobes circumferentially spaced around the mounting shaft and located above a stop member that separates the lower sealing section from the upper locking section. The collar flexes out of round when it is mounted over the locking lobes on the mounting shaft. The circumferential shelf on the tip isolates the tip barrel from distortion to enable robust sealing in the barrel below the shelf.
