Amplifiers

WPI have 50 years experience of designing & selling biological amplifiers. Whether its intra- or extra-cellular recording, ECG, EMG, EEG...

An amplifier, in simplest terms, is an electronic device that magnifies an input signal. In this case, the amplifier magnifies the small voltage changes in cells or tissues. Not all amplifiers are created equal. The way an amplifier is designed to handle the intrinsic noise of an electronic device and the bandwidth limitations of the amplifier greatly affects the quality and sustainability of the final output signal. WPI has been designing and building amplifiers since 1967. Quality components is the key to our faithful reproduction of an input signal. WPI offers intracellular amplifiers for measurements inside a single cell, extracellular amplifiers for measurement in interstitial fluid (outside a cell), transducer amplifiers for pressure, force displacement, temperature measurements and more.

The purchase of a low-noise amplifier pays dividends in the end. WPI’s amplifiers were engineered for the bio-medical researcher. While 20-30μV of noise is common in bio-amplifiers, WPI’s DAM series amplifiers generate 0.4μV RMS (root mean squared) at 0.1-100Hz. (That’s equal to about 2μV peak to peak.)
