Available in either a single- or dual-headstage configuration, the dPatch amplifier’s architecture makes swapping headstages, or adding a second one to a single-headstage version, a plug-and-play operation. The two headstages are independently configurable for either voltage clamp or true high-speed current clamp. Data is streamed from each headstage in parallel and fully synchronized.

5 Mhz Sampling Rate, Up To 22-Bit Resolution

One unique feature with dPatch is the headstage data sampling system. Each headstage is continually sampled at 5 MHz. Output filtering has thirteen settings between 100 Hz and 1 MHz. A resolution of 18 bits is achieved at 1 MHz. For lower filter settings, automatic downsampling increases resolution while optimizing data rates. At a bandwidth setting of 1 kHz, the dPatch system provides a signal resolution of better than 22 bits.

Optimal noise performance in both the capacitive and resistive feedback ranges

When other products remove thermal energy from the headstage circuitry, it in turn heats up the headstage housing. That leads to thermal drift of the pipette and other, cumbersome side effects. One of the development goals of the dPatch headstage was achieving a comparable noise performance at room temperature, without the need for a cooled headstage. In the two resistive feedback modes, the dPatch amplifier is even quieter than any of the competitor systems.

Built-in data acquisition system means no third-party digitizer

Using a multiplexer-free design, the dPatch provides 8 fully differential analog input channels, 4 analog output channels, and 16 digital outputs (TTL). All I/O channels are sampled continuously (200 kHz for analog inputs, 250 kHz for analog and digital outputs) and available through the user interface.

Sutterpatch Software

The dPatch amplifier, in combination with SutterPatch software, has been engineered to automatically capture and store all amplifier settings, stimulus information and external experiment parameters, and associate them in time with the raw data traces. This includes all amplifier and acquisition settings, as well as timing and progress of the experiment. Fully integrated computer control of the amplifier stages means that the acquisition software is aware of the internal state of the amplifier and digitizer at all times and can track any changes that may occur. This is independent of whether a change is triggered automatically or initiated by the user.

Tracking Of Other External Data

In addition to status changes in connected hardware that are automatically tracked, the researcher can manually trigger tags to document events like stimulus application using instruments not connected to the amplifier.

Information about environmental parameters and a more detailed specification of sample properties can be recorded and stored with the raw data. A total of over 600 metadata attributes are supported. Examples include: animal species, genotype, date/time when a cell sample was prepared, recording solutions, pipette resistance, hardware properties, and detailed information about stimuli applied.

Data Visualization and Analysis

SutterPatch software has been designed to simplify the navigation and analysis of complex datasets. The scope window supports multiple view modes in both two-dimensional and an innovative three-dimensional display. The 3D view is particularly useful during assay development. Built on top of the latest version of the proven Igor Pro platform, SutterPatch combines native Igor Pro functionality with a wealth of features that are tailored to electrophysiology applications. Both the newcomer and the experienced user of patch clamp programs will feel comfortable using SutterPatch software.

Application modules provide focused functionality for particular applications.
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.

Pipette Holders

 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)
Note: Quartz is fragile and may crack or shatter on impact. Treat your quartz electrode holder with the same care you would with any optical component.

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.

Operating systems installed within virtualization software platforms such as VMware and Parallels are not supported.
