The EPC 10 USB amplifiers are available with one (EPC 10 USB), two (EPC 10 USB Double), three (EPC 10 USB Triple) or four (EPC 10 USB Quadro) amplifiers. This hardware product line is fully integrated with HEKA's data acquisition LIH 8+8 AD/DA interface. The interface utilizes USB 2.0 and high speed processing technologies. The advanced integration of the EPC 10 USB with the interface and software minimizes total recording noise, eliminates compatibility problems and reduces additional equipment expenses and set-up time.
The digital control of all amplifier functions has been designed with two advantages in mind. Firstly, as the computer controls the functions of the amplifier, the data acquisition program can access and store variables that describe all of the settings during an experiment. Secondly, computer control allows the user to highly automated the experiments.
These include automatic switching (e.g, switching between the settings for establishing a seal or those for single channel recording) and also the automatic adjustment of capacitance transients cancellation and series resistance compensation. In fact, digital control of every adjustable parameter in the amplifier circuitry is implemented, including the calibration adjustments.
The EPC 10 USB is a complete data acquisition system, which can be controlled with HEKA's PATCHMASTER or PATCHMASTER NEXT software. A DLL (dynamic link library) is available to allow access of the system from a custom written application. The EPC 10 USB patch clamp amplifier, combined with a computer and PATCHMASTER or PATCHMASTER NEXT software is equivalent to a fully equipped setup, which includes a patch clamp amplifier, a digital storage oscilloscope, a variable analog filter, a sophisticated pulse generator, and a fully featured data acquisition and analysis system.
