ER230 HV Sequencer
THIS PRODUCT IS NO LONGER AVAILABLE. It has been superseded by the ER430 HV Sequencer.
*********************************************************************************************************************
The ER230 sequencer provides two independently controllable high voltage channels suitable for microchip electrophoresis, or electrokinetic chromatography. It can also be used a voltage source for micro reactors and mixers based on EOF pumping.
A second unit can be piggybacked on the first giving up to four high voltage channels operating on the one clock (ie all pulses are accurately synchronised).
Multiple units (or pairs of units) can be operated as virtual RS232 devices using a serial protocol over a USB connection and compatible software such as LabVIEW, WinWedge, or HyperTerminal.
