EX1
The Dagan EX1 Amplifier is 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 EX1 is perfect single or multi-channel extracellular amplifier systems with gains of 10 to 20 000.
