【発明の名称】化学溶液に高圧電流を供給する装置
Document Type and Number:
Japanese Patent JP2848599
Kind Code:
B2
Abstract:
A transfection high-voltage controller for directing high-voltage currents to a suspension of cells and DNA comprising a control section, a power store, and a high-joule switch. Under control of the control section, the high-joule switch directs a high-voltage current from the power store to a load such as a cuvette. The high-joule switch comprises a semiconductor controlled rectifier (SCR) having a gate coupled to the control unit for triggering the device, an anode for receiving the high-voltage current from the power store, and a cathode for delivering the high-voltage current to the cuvette. A current sink may be connected to the anode of the SCR to render it non-conductive a predetermined time after the high-voltage current appears at the cathode. Multiple SCRs may be connected in series to support voltages over 3,000 and currents in excess of 125 amperes, and a trigger control unit may be attached to the gate of each SCR in the series to effect simultaneous or serial triggering of the group.
