Dagan IX 1

Einkanal-intrazellulärer Vorverstärker
Beschreibung

 

The IX 1 is a single channel microelectrode preamplifier designed to serve a wide variety of applications including: Intracellular recording; Extracellular recording; Teaching application requiring ease of use.  The 1X1 is a complete instrument with DC current passing capability, filtering, and electrode impedance testing.

Features

  • Small Box Headstage with choice of five current ranges
  • Buzz with independent amplitude control to facilitate cell penetration
  • Small size takes up less space, yet is uncluttered, easy to use, with well defined controls
  • Optional ×1000 Voltage Gain AC Coupled Headstage for extracellular recording (Model 8024-15).
