Bio Amps
ECG / EKG, EEG, EOG, & EMG Biological Amplifiers
Overview
ADInstruments Bio Amps are galvanically isolated, high-performance differential biological potential amplifiers optimized to measure a wide variety of biological signals such as ECG / EKG, EMG, EOG, and EEG recordings.
In conjunction with our PowerLab data acquisition system options and LabChart analysis software, a wide range of filters are available for processing biosignals from a variety of research areas such as:
- Autonomic and sympathetic nervous system function
- Cardiovascular disease and myocardial dysfunction
- Muscle activation and fatigue
- Evoked responses and stimulation
- Heart rate variability/arrhythmia
Our Single, Dual, Quad and Octal Bio Amps are supplied with Bio Amp Connection Cables and Lead Wires making them suitable and safe for both human and animal connection. An audio output is also available to help monitor signals.
Accessories suitable for use with Bio Amps include:
- Reusable ECG Electrodes
- Chest ECG Electrodes (suction)
- EEG Flat Electrodes
- ECG Lead Switch Box
- EEG Cap Systems
- Adapter Packs
- Octal Bio Amp Linking Cables
ADInstruments signal conditioners only function with a C Series Front End Interface or traditional PowerLab data acquisition device and therefore are not suitable for use with other data acquisition systems.
Amplifiers to Power Your Biological Data Acquisition
ADInstruments’ suite of Bio Amps are tailored to your acquisition and amplification needs. All amplifiers are galvanically isolated, and made specifically for the acquisition of bio signals such as action potentials and surface voltage fluctuation, powering the acquisition and recording of ECG, EMG, EOG and EEG. High input impedance and common mode rejection ratio (CMRR) support improved noise reduction over ultra-high bandwidth, increasing the ease of experiment setup and data acquisition.
Use your Bio Amp in conjunction with LabChart, a powerful software package that grants users ultimate customization in signal acquisition - from amplitude analysis to signal averaging.
Amplifiers connect to a set of data acquisition modules with PowerLab at the core. This easy integration of analog transducers and signal conditioners promotes a radically streamlined workflow.
