Abstract
A pipette tip assembly includes a pipette tip having a first open end adapted to receive a pipette tip mounting shaft of a pipette, a second open end, and an open channel therebetween. The assembly also includes a mixer disposed in the channel, the mixer including at least one porous mixing device. The at least one porous mixing device includes a three-dimensional lattice defining a plurality of tortuous, interconnecting passages therethrough, and has physical characteristics to sufficiently mix first and second fluids drawn or expelled through the mixer, which characteristics include a selected one or more of mean flow pore size, thickness and porosity.
