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.
