920000 Model 3100 Intracellular Electrometer Matrix The syringe holder firmly holdsModel 3100 Intracellular Electrometer The Model 3100s uses an advanced capacitance Ringer for clearing electrode tips and enhancing the membrane penetration of neurons. The Ringers 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
