Details

The bridge amplifier module BA-01M is a wide bandwidth high impedance intracellular amplifier for recordings with sharp microelectrodes or suction (patch) pipettes. Currently, BA amplifiers are used in vertebrate (rat, mouse, cat, fish etc.) and invertebrate (leech, crab, snail, insect etc.) neurons, muscle cells, other excitable tissue and plant cells.

The BA-01M EPMS module has the same specification as the BA-01X 19″ stand-alone device except that it has only one current input range (1 nA/V), only one potential output (x10 mV), only one bridge balance range (0-1000 MΩ) and no oscillation shut-off.

Bridge amplifiers are also available as 19″ stand-alone devices.
