ISO-80

Overview

Benefits

• Ultra quiet DC power supply
• Intrinsic low susceptibility to ground loops
• High signal to noise ratio due to remote head stage
• Small footprint
• Stimulation/histological marking current

Applications

• Amplifying bio-potentials using metal microelectrodes
• Brain slice field potentials
• EAG (Electroantennogram)
• ERG (Electroretinogram)
• Monitor extracellular nerve action potentials
• Use for cell marking, stimulation or electrode cleaning
• In vivo cortical recording

ISO-80 Isolated Bio-Amplifier With Active Probe

The ISO-80 provides low noise AC coupled amplification and offers excellent recording performance for monitoring extracellular nerve action potentials in vitro and in living animals. The ISO-80 is provided with a remote headstage (1 m cable) which incorporates an electrode impedance test function and a constant current stimulator. The constant current stimulator can be used for cell marking, stimulation or electrode cleaning. Typical applications include measuring EMG, EEG, extracellular and action potentials in vitro or in vivo. The ISO-80 system is DC isolated from the subject ground and employs state of the art electro-magnetic shielding for improved noise rejection. The amplifier employs both high pass and low pass filtering with gain from 100 to 10,000. The lowest low-pass setting is 5 Hz and the upper passband is 10 kHz.

• Battery powered, rechargeable
• High pass and low pass filtering
• Active remote headstage
• AC only amplification
• Electrode impedance test function
• Electrode current generation with polarity select
• Variable output positioning
• The ISO-80P replacement probe does not need the ISO-80 to be sent in for calibration
