Our Flagship Electrochemical Probe Scanner ELP 3

The HEKA ELP 3 is an Electrochemical Probe Scanner with integrated inverted microscope optics. It is the perfect platform to be used with biological samples in SECM and SICM experiments.

The HEKA ELP 3 system combines the ElProScan with Transmitted Light Imaging and Fluorescence Imaging techniques in one instrument. Transmitted light imaging or fluorescence imaging can be performed simultaneously to the scan process.

The HEKA ELP 3 system provides a motorized focus drive which can be easily controlled during the scan process via a joystick. Manipulations on the focus can be performed without touching the scan setup.

The HEKA ElProScan is an integrated system, which allows control of all components by one software program and it consists of scientific grade hardware components to achieve optimal performance. The HEKA ElProScan is the only system which can perform measurements in an extremely wide current range up to 2 A. It also operates as a standard (Bi-)potentiostat/Galvanostat, thus, making it usable for many other electrochemical applications also.

Low current preamplifiers allow high-resolution low-noise recordings in the low pA range. The HEKA ElProScan features a positioning system with a large travel range and a resolution in the nanometer range. No compromises have been made with respect to the mechanical setup components to guarantee high accuracy and reproducibility.

The whole ElProScan system is controlled by our well established POTMASTER software and the embedded ElProScan extension. POTMASTER is a data acquisition program that provides sophisticated tools for waveform generation, data review and editing as well as online analysis.
