ELECTROPIPETTOR AND COMPENSATION MEANS FOR ELECTROPHORETIC BIAS

A channel (140) is divised into portions (142, 144). The sidewalls of each channel portion (142, 144) have surface charges of opposite polarity. The two channel portions (142, 144) are physically connected together by a salt bridge (133), such as a glass frit or gel layer. The salt bridge (133) sepa...

More Information
Summary:A channel (140) is divised into portions (142, 144). The sidewalls of each channel portion (142, 144) have surface charges of opposite polarity. The two channel portions (142, 144) are physically connected together by a salt bridge (133), such as a glass frit or gel layer. The salt bridge (133) separates the fluids in channel (140) from an ionic fluid reservoir (135). To impart electroosmotic and electrophoretic forces along the channel (140) between parts A and B, respectively. Additionally, a third electrode (137) is placed in the reservoir (135).</SDO AB>
