Can we help you?

The dPatch Integrated Digital Patch Clamp Amplifier is a computer-controlled single- or dual-headstage system optimized for both single-channel and whole-cell recording applications.

The resulting design represents a complete rethinking of how to best reduce noise and preserve signal to get the cleanest recordings possible, at a bandwidth that far exceeds anything else on the market. The dPatch amplifier system's digital architecture uses state-of-the-art methods in signal processing, such as field-programmable gate arrays (FPGAs) and Arm Core processors – technologies unavailable when the leading amplifiers in the market were designed well over 20 years ago. The processing power of this design FINALLY enables fully integrated dynamic clamp, as well as digital capacitance and resistance compensation. The included SutterPatch® Software facilitates data acquisition, mangement and analysis with an intuitive and easy to learn interface.

Available in either a single- or dual-headstage configuration, the dPatch amplifier system’s architecture makes swapping headstages, or adding a second one to a single-headstage unit, a plug-and-play operation. The two headstages are independently configurable for either voltage clamp or FastFollower™ current clamp.

Currently available:

  • Event Detection Module: A deconvolution algorithm that excels at detecting miniature synaptic events even on a noisy background.
  • Action Potential Analysis Module: Phase plane plot, timing and waveform statistics.
  • Camera Module: An easy way to document the identity and condition of the recorded cell.


While the dPatch System is ready for cutting-edge research, its feature set makes it immediately valuable in any lab setting.

Ground Point

The Ground Point GP-17 provides reliable, low resistance connections for a star ground configuration, the proven method to avoid ground loops in any electrophysiology setup. Accepts 9 banana plugs + 8 bare wires up to 10 gauge or banana plugs. The baseplate mounts directly on imperial or metric air table tops with the included ¼-20 and M6 screws. Made of solid, machined brass with plated banana/clamp connectors.

dPatch Expansion Panel

Quartz Pipette Holder

While polycarbonate is a proven material for patch pipette holders, it undergoes significant thermal expansion. Uneven warming may lead to motion of the pipette tip and is often incorrectly perceived as drift in the micromanipulator. Quartz has a significantly lower thermal expansion coefficient and virtually eliminates thermal drift. (Link to video: Minimizing thermal expansion with the Sutter Instrument Quartz Pipette Holder)


  • Hardware architecture enables all data conversion to be performed near the preparation, well away from known noise sources, such as power supplies and high-speed digital circuitry.
  • Voltage clamp and true current clamp modes with smart switching between modes to avoid current artifacts
  • Three choices of headstage feedback elements to optimize both single-channel and whole-cell recording

See for technical details. Preliminary experiments indicate that SutterPatch Software runs on these computers, both under Igor Pro 8 and 9, and with each of the Sutter Amplifier Systems connected. However, as with each new technology, we cannot fully exclude incompatibilities. 3 USB 3.0 ports are compatible with USB 2.0 High Speed specifications. Slower USB 2.0 ‘full-speed’ ports, which are sometimes found on older Windows PCs or USB add-in cards, are not supported. To check for High Speed USB 2.0 or USB 3.0 on a PC computer running Windows, look in the Control Panel > Device Manager > Universal Serial Bus controllers section for “Enhanced” host controllers. As this does not provide any mapping information to the computer’s physical ports, and there can be a mix of USB port versions, you should check individual USB ports for USB 2.0/3.0 High Speed operational performance. As a visual indicator, USB 3.0 ports are often color coded blue. USB hubs are not supported. USB add-in cards, even if they formally meet High Speed or Super Speed specifications, are not recommended. They are often architecturally configured as USB hubs and may lead to intermittent transfer errors that are hard to troubleshoot.
