Model 3100 Intracellular Electrometer The Model 3100’s uses an advanced capacitance “Ringer” for clearing electrode tips and enhancing the membrane penetration of neurons. The Ringer’s amplitude and frequency of the pulsed oscillations sent to the electrode can be adjusted. Low pass filtering combined with a line frequency notch filter are available for the researcher to diminish extraneous frequencies and external line noise. The current injection system allows for both internally generated and externally generated current. This current can be set for continuous or momentary injection. The sum of the current can be gated by an external TTL logic signal source. The small size of the amplifier and its remote power supply offer the advantage of placing the amplifier near to the experimental set up. For example, the amplifier can be placed within a Faraday cage with minimal power-line interference. he Model 3100’s uses an advanced capacitance “Ringer” for clearing electrode tips and enhancing the membrane penetration of neurons.
