1. Patch Clamp equipment

HEKA offers six patch clamp amplifiers. Each instrument is suitable for both whole cell and single channel recordings. All amplifiers include voltage clamp and current clamp mode, filters, capacitance compensation, and series resistance circuitry. The software controlled EPC 10 family patch clamp amplifiers set the highest standard for electrophysiological data acquisition systems; and in combination with our PATCHMASTER software, they are best suitable for complying with GLP rules and FDA regulations. A data acquisition system for patch clamp experiments consists of an amplifier, an interface with AD/DA converter, a computer and software. Below you find our recommendations for complete data acquisition systems to be connected to a computer. See our brochures for details.

1.1 Computer Control of EPC 10 Patch Clamp Amplifiers

  • On Windows operating systems, the EPC 10 family of patch clamp amplifiers are supported by our acquisition software packages PATCHMASTER and TIDA 5.x.
    TIDA does not yet support the new USB amplifiers and LIH 8+8 interfaces!
  • On Mac OS 9 and Mac OS X , the EPC 10 family of patch clamp amplifiers are supported by our new multichannel acquisition/stimulation software package PATCHMASTER. The new "Intel Macs" (Mac Pro) are supported by Patchmaster 2.30 or above !

    Voltammetric Amplifier EVA 8

    The EPC 8 - successor of the EPC 7 - is a stand-alone amplifier with manual controls. The following functions can also be controlled by software: gain, mode, filter setting, and phase tracking. As stand-alone amplifier, it can be combined with any data acquisition system. In order to use the software-controlled functions, it must be driven by our software PATCHMASTER or TIDA in combination with the LIH 8+8. Alternatively, an user can write his own software to control the amplifier and connect the EPC 8 to a computer board with 16-bit parallel port.

    The EVA 8 is a stand-alone voltammetric amplifier for microelectrode technology with manual controls. The following functions can also be controlled by software: gain, mode, filter setting.

    2. Computer System Requirements (Macintosh and PC)

    The computer configuration depends on the actual needs of your experiments, e.g. sampling rate and duration of continuous data acquisition. While the recommended computer configuration is sufficient for most patch clamp experiments, the configuration may have to be extended for more demanding experiments. For fast continuous data acquisition it may be necessary to temporarily write data to RAM rather than directly to disk. This option requires a RAM size large enough to accommodate the data in memory. Furthermore, a well equipped computer reduces the time required for data storage, and also makes data analysis more convenient. If you intend to run other programs simultaneously with our data acquisition software, e.g. for photometric measurements, a fast computer can help to avoid timing problems. For external data storage, CD writer, ZIP disks or optical disks are recommended --> Computer configuration.
