EMG pre-amplifiers

Motion Lab Systems offers the widest range of EMG and biological signal amplifiers of any manufacturer and can provide custom solutions if required.

All preamplifiers are manufactured to the highest standards in a GMP inspected facility and use only materials that meet current FDA standards for bio compatibility. All of our preamplifiers are made from biocompatible materials and are latex free.

All preamplifiers feature a fixed gain, high input impedance, high common mode rejection, and include high and low pass filters. Each preamplifier is available with one or more different connector and wiring options - details of the connections and pinout can be found here. The preamplifiers support a number of different input options, including fine-wire and discrete Ag/AgCl disposable gel electrodes.

It is most important to note that all Motion Lab Systems Preamplifiers do not offer any electrical isolation functions as this is a feature built into our EMG systems - there is a direct electrical connection between the preamplifier ground connection and the connector.

Please contact us for price and availability - most standard x20 and x300 gain preamplifier designs are in stock and can be shipped on receipt of a purchase order or payment via credit card.

Obsolete Preamplifiers

The Z03 and Y03 designs are intended for our older MA-100 and MA-200 system when ordered with the appropriate connector. If you do not see your specific preamplifier listed here then please check our preamplifier cross reference page to see if a substitute is available.

Custom Designs
Our preamplifier designs are flexible and can be modified to suit your special applications or unique requirements - please call us call for a quotation with information about the gain and bandwidth required. Single unit and quantity pricing on request.
