Neuro Amplifier EX
The Neuro Amp EX (MLT185) is a low noise and high gain device which makes it suitable for all recording environments requiring a wide bandpass (100 Hz to 5 kHz) and a high signal to noise ratio. Animal applications include extracellular recordings from single cells or groups of cells single nerve fiber recordings (split-nerve preparation or human microneurography).
The Neuro Amp EX headstage (included) provides a gain of 100x with a 10Hz High Pass filter. The cable shielding is directly connected to the casing, limiting the need for additional shielding at the input terminals. The device is certified safe for human connection with the supplied MLT185 Neuro Amp EX headstage.
The Neuro Amp EX is also supplied with six male (6) Amphenol connectors for customization of microelectrode adapters for use with the MLT185 Neuro Amp EX Headstage (microelectrodes are not supplied).
The Neuro Amp EX in Conjunction with PowerLab, LabChart or Scope Provides:
- Full electrical isolation from power-line (mains) circuitry to guarantee subject safety
- A low-noise, high-gain differential amplifier specifically designed for recording extracellular potentials
- Software-controlled low-pass, high-pass, notch and mains filters to remove unwanted signal frequencies for particular uses
- Audio output to listen to neural signals.
Please note that the Neuro Amp EX is not suitable for intracellular recording with glass microelectrodes.
