The CHEM-CLAMP is designed to be a dedicated instrument for Voltammetric and Amperometric Recording. Although the internal design of the CHEM-CLAMP is similar to low noise Patch and Whole cell clamps designed by Dagan Corporation, the price is kept down by including only features needed for Voltammetric and Amperometric Recording.
