npi electronic ISO-STIM 01B

The ISO-STIM stimulus isolation unit is designed for the application of extracellular stimuli, e.g. in brain slices. It is able to generate a bipolar stimulus without delay between positive and negative part of the stimulus.

npi electronic ISO-STIM 01B
Adjustable amplitude

The amplitude can be set manually with a ten-turn potentiometer

Adjustable Interphase Gap

Change the length of the gap between stimuli

Complex timing options

Combine with the TMR-01B to create complex stimulation patterns

2 pulse modes: direct input: TTL duration = pulse duration (with bipolar option) trigger input: pulse duration set by internal timer (10 μs ... 10 ms).

Voltage or current output max. 100 V/10 MA unipolar or bipolar.

2 external power supply optionsL line: (input 90 V...240 V AC) battery: ±40 V up to ±100 V (user selectable)
