Molecular Devices Axon™ Digidata® 1550A plus HumSilencer™


Axon™ Digidata® 1550A plus HumSilencer™

For a variety of electrophysiology recordings including single-channel recordings, whole-cell voltage- and current-clamp recordings, intracellular sharp electrode recordings, extracellular field potential recordings in ion channel, neuroscience, nanopore, voltammetry studies.   
The Axon™ Digidata® 1550A plus HumSilencer™ Adaptive Noise Cancellation brings a new level of simplicity to your electrophysiology workflows. Blending the precision and quality of the Axon Digidata 1550 with fast, hassle-free 50/60 Hz line-frequency noise elimination, the Digidata 1550A frees you from the anxiety of this often unanticipated issue. Experiments can move forward more reliably and small biological signals no longer remain obscured by noise now that you have the ability to eliminate line-frequency noise in less than one second and with only a single click.   
What Is the HumSilencer Feature?   
The HumSilencer feature is advanced technology that learns the local line-frequency noise patterns and associated high-frequency harmonics and removes them from the incoming signal in a filter-free way. Controlled through a simple ON/OFF check box in the Axon AxoScope or Axon Clampex software, the HumSilencer is easy to use, enabling (or disabling) subtraction of line-frequency noise from your signal with a single click.
