ePatch

The world’s smallest integrated patch clamp amplifier and data acquisition system for whole-cell and single-channel recordings.

A very low noise one channel amplifier enabling high bandwidth acquisitions for voltage-clamp measurements.

The miniaturized ePatch amplifier integrates in a small headstage the low-noise amplifier, the pulse generator and the digitizer into only 42 x 18 x 78 mm and it is connected directly to the USB port of a laptop without the need of any other external bulky digitizer and control unit.
