Abstract
In a pipette device, a suction device applies suction to a pipette tip to draw liquid into the pipette tip. A porous plastic plug is mounted in the pipette tip to prevent contamination of the suction device by the liquid sample. The median pore size in the porous plastic plug ranges from 3 microns to an upper limit which varies with the hydrophobicity of the material of the plug.
