Abstract
A lid for a well plate is provided. A pin penetrates the lid and projects downwardly into a well of the well plate. An electrical charge is applied to the pin and an electrical charge of opposite polarity is applied to an electrically conductive portion of a corresponding well, generating a small flow of electrical current and corresponding electrical fields within the well. Charged materials, such as DNA, selectably are attracted to the pin and segregated from the liquid sample.
