Stimulus Isolator

Overview:

The ML1101 Stimulus Isolator insulates the output for the ML1001 Electronic Stimulator from ground. This minimizes the area of stimulation to ensure greater precision, while reducing stimulation artifacts and facilitating the observation of evoked action potentials.  The ML1101 can only operate with a stimulator and is configured for use with the ML1001 Electronic Stimulator.

Features:

• Numeric power indication: Indicates the amount of power that goes through the device.
• Constant-voltage/current output of both positive and negative polarity: The device can output the biphasic wave constant voltage that is essential for evoked action potential induction during experiments with cells and other samples.
• Excellent input and output linearity: The output changes linearly with respect to the amplitude of the input signal.
• Built-in over current alarm: An alarm is generated when the electrode resistance of the load is too large for the set current to pass.

Applications:

• Neurophysiology
• Patch clamping
• Extracellular recording
