Abstract
Pipetting containers, such as reservoirs, reservoir liners, microplates, PCR plates, microtubes and PCR tubes, include anti-vacuum channels on the bottom wall of the receptacle to prevent a pipette tip vacuum engaging the wall during aspiration. The groupings of anti-vacuum channels are located on the bottom surface facing upward into the basin that holds liquid samples or reagents. The anti-vacuum channels also lower the required working volume for pipetting and reduce liquid waste.
Claims9
A pipetting container comprising:
- a receptacle for holding liquid reagents or samples for pipetting, the receptacle having a bottom wall, and at least one grouping of interconnected anti-vacuum channels on an upper surface of the bottom wall and exposed upwardly into the receptacle in which liquid sample or liquid reagent is held for pipetting;
- wherein the upper surface of the bottom wall of the receptacle is hydrophilic;
- and
- further wherein the container is a disposable liner that is configured to sit in a reusable base, and said liner comprises multiple upstanding walls that separate the container receptacle into multiple separate basins with each upstanding wall having a bottom end that is sealed with the bottom wall of the container receptacle, and further wherein the upper surface of the bottom wall includes multiple groupings of interconnected anti-vacuum channels on the upper surface of the bottom wall in each of the multiple separate basins.

A pipetting container comprising:
- a receptacle for holding liquid reagents or samples for pipetting, the receptacle having a bottom wall, and at least one grouping of interconnected anti-vacuum channels on an upper surface of the bottom wall and exposed upwardly into the receptacle in which liquid sample or liquid reagent is held for pipetting;
- wherein
- the upper surface of the bottom wall of the receptacle is hydrophilic;
- the container is a laboratory tube having a cylindrical sidewall and a single grouping of interconnected anti-vacuum channels on the upper surface of the bottom wall;
- at least a portion of the upper surface of the bottom wall is flat, and the portion of the upper surface of the bottom wall with the single grouping of interconnected anti-vacuum channels is flat except for the interconnected anti-vacuum channels;
- the single grouping of interconnected anti-vacuum channels on the bottom wall contains a first pair of perpendicular and intersecting channels with the intersection of the channels defining a center point for the grouping, a second pair of perpendicular channels rotated 45° from the first pair, said second pair of channels being aligned to intersect at said center point but interrupted in the vicinity of the center point, and at least one circular channel that intersects each of the channels of the first and second pair of perpendicular and intersecting channels;
- the at least one circular channel comprises an inner circular channel and an outer circular channel and each of the inner and the outer circular channels intersects each of the channels of the first and second pair of perpendicular and intersecting channels;
- and
- the pipetting container further comprises additional channels extending from the inner circular channel through the outer circular channel.
