EX-1 Single Channel & EX4-400 Quad Channel

Differential Extracellular Amplifiers (CORNERSTONE Series)

The EX4-400 and EX1 Amplifiers are ideal for all non-human applications which require single or multiple channel AC or DC amplification with High and Low frequency filtering. With the optional differential headstage, the EX4-400 and EX1 are perfect single or multi-channel extracellular amplifier systems with gains of 10 to 20,000.
