MODEL 3100 INTRACELLULAR ELECTROMETER

The Model 3100 Intracellular Electrometer is a simple to use low cost full function intracellular amplifier. Research quality recordings made possible by an instrument you can purchase on a teaching budget.

The amplifiers current compensation circuit includes a dual-transient control that provides extremely precise adjustments to transient suppression during membrane recordings. Its DC balance control eliminates the need for an external bridge or a differential input oscilloscope. The DC offset control can eliminate up to ±1V of offset.

An internal square-wave generator supplies a 100Hz current pulse to determine electrode resistance. Capacity compensation can adjust up to 35pF of electrode capacitance. Additional stray capacitance can be reduced by using the driven shield connector on the head stage probe.

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.

MODEL 1700 DIFFERENTIAL AC AMPLIFIER

The Model 1700 Differential AC Amplifier contains 4 independent amplifier channels in a single enclosure enabling the researcher to record multiple signals simultaneously. Each channel contains a high-gain, low-noise differential stage followed by low-pass, high pass, and notch filters. A connection is also provided for a stimulator input so that recording or stimulating through the same electrode is possible without having to change cabling.

Standard gain settings are x100, x1000 or x10,000, but they can be modified to meet your specific requirements. High and Low Pass filters are 2nd order Butterworth filters, and like the gain, the standard settings can be modified to meet your needs if required.

The Model 1700 Differential AC Amplifier is designed for use with low impedance (<1.5 MΩ) electrodes, and is therefore suitable for use with suction, nerve cuff, hook, surface, and simple metal electrodes. Optional record only headstages are available for situations where you would like to record from electrodes with higher impedances such as those used when recording neural spike action potentials.
