ePatch

The new tiny amplifier designed for high quality patch clamp recordings in both voltage clamp and current clamp modes

The low-noise amplifier, the pulse generator and the digitizer are included within the small headstage (only 42 x 18 x 78 mm) that can be directly installed to the micromanipulator mounting plate and powered by the USB port of a laptop without the need of any external bulky digitizer and control unit.

Applications

EZ Patch - the new ePatch software interface

EZ Patch software is the new patch-clamp electrophysiology software developed and released by Elements for easy control of the ePatch amplifier. EZ Patch allows:

  • Customizable user-friendly Windows-format interface
  • Real-time display of voltage and current digitized data
  • Parametric voltage protocols editor
  • Automatic or manual control of compensation settings
  • Membrane parameters estimation to keep track of cell health
  • Real-time data analysis (C-fast – estimation, noise, I/V graph, current histogram, etc.)
  • Digital LabBook
  • Data output saving formats: .abf
  • Available for Windows and Mac OS

Discover how easy it is to use EZ Patch by watching the demo videos in the Videos section below.
