Biological Amplifiers

详情

Main features The CRS-INT is designed to measure QT, evoked potentials and single cell membrane potentials in "in-vitro" conditions. The amplifier exhibits low noise, high resistance and low capacitance. It consists of two items, as INT amplifier and a preamplifier (head stage). The task of preamplifier is to enable the impedance connection between the electrode and the end-amplifier (x1 amplification). The INT amplifier makes the checking functions (resistance measurement, capacitance compensation), the *0 folds amplification and helps monitoring the insertion of the electrode with the built in sound generator. The *-digit LED display enables to read the mV values during the entire experiment (except of the resistance value). Parameters of INT amplifier Input resistance: *0¹² ohm Amplification: 1x, *0x Bucking: ±**0 mV Impedance measurement: ****0 M ohm Calibration signal: **0 Hz square wave Insertation monitor: audio Display: *-digit LED Parameters of pre-amplifier Input resistance: *0 G ohm Amplification: X1 Input capacitance: 0–*5 pF (compensated) Housing: aluminum Cable Length: *0 mm, shielded O.D.: *5 mm Microelectrode holder connector: standard 2 mm I.D.
