The ECM® 2001 is a multi-purpose Electro Cell Manipulation generator capable of producing a proprietary AC waveform for benign dielectrophoretic alignment of cells, and a square DC waveform for cell fusion. Electrofusion is carried out by applying both the AC and DC pulse waveforms. Microsecond switch-over time from AC to DC allows for highly efficient fusion. After fusion, the AC pulse reapplication maintains compression of the cells following the DC pulse for the rounding off process; resulting in a higher number of hybrids. The 1 MHz AC pulse aligns cells together in “real time”, saving time (seconds vs. hours) in comparison to PEG methods. Blastomeres and oocytes can also be aligned to the correct position for better fusion accuracy during nuclear transfer and embryo manipulation.

  • Versatile Platform System
  • Microprocessor Controlled Precision
  • Wide Range of Parameters


Utilizing the ECM® 2001 for standard mammalian cell transfections is simple; the AC feature is turned off and the DC mode is set as a square wave electroporation device. The range of voltages and pulse lengths that can be programmed, coupled with the ability to carry out up to 9 pulses per experiment, make this an extremely versatile system for any lab.
