Abstract
A pipetting reservoir kit includes a base, a disposable liner, and a lid. The disposable liner includes anti-vacuum channels on the bottom wall to prevent a pipette tip vacuum engaging the wall during aspiration. The groupings of anti-vacuum channels located on the bottom surface of the liner face upward into the basin that holds liquid samples or reagents. The groupings of anti-vacuum channels are spaced in an array 4.5 mm apart for a 384 pipetting head and 9 mm apart for a 96 pipetting head. The anti-vacuum channels also lower the required working volume for the liner and reduce liquid waste.
