Remote Headstage Easily mounted in any manipulator, this small probe, containing the first stage of amplification, includes a microelectrode holder, which plugs directly into the probe input
Battery Power Four 9V alkaline batteries power the Electro 705 for approximately 500 hours giving a super clean, low noise source of power making the Electro 705 the quietest amplifier available. Batteries can be easily tested by the press of a button.
Capacitance Compensation Corrects for loss of rise time caused by the presence of electrode capacity. Up to 50pF of electrode shunt capacity may be neutralised.
Driven Guard Shield Stray capacitance can be further reduced by placing the driven guard shield (included) over the microelectrode holder at the input end of the probe.
Tickler Circuit A momentary oscillation that helps achieve cell penetration.
Electrode Resistance Test The Electro 705 provides a 1nA electrode test current. Electrode resistance is monitored at the 1X output as a voltage (1mV/M).
Probe Test Port Allows the convenience of testing the amplifier's intrinsic noise and gain without cumbersome external test hookups. Gate leakage current can also be adjusted with minimum effort.
Baseline Position Control Adds or subtracts up to 300mV to the headstage output, allowing artifact voltages such as liquid junction potentials to be nulled prior to recording.
Differential Output Two Electro 704's can be connected in tandem to create an optional differential amplifier probe system.
