Model 3100

Intracellular Electrometer (A-M Systems)


The Model 3100 Intracellular Electrometer is a simple to use, low cost intracellular amplifier.  It comes equipped with a small and light weight probe measuring 1.1 cm in diameter by 5.6 cm long and weighing only 10 grams.

The dual-transient control provides extremely precise adjustments to transient suppression during membrane recordings.  The DC balance control eliminates the need for an external bridge or a differential input oscilloscope.  The DC offset provides electrode offset control up to ±1 V.  An internal square-wave generator supplies a 100 Hz current pulse to determine electrode resistance.  It is also useful to adjust capacitance compensation.  Capacity compensation can adjust up to 35 pF of electrode capacitance.  Additional stray capacitance can be reduced by using the driven shield connector on the head stage probe.
