Working with biological cells and tissues

The HEKA ELP 3 is an Electrochemical Probe Scanner with integrated inverted microscope optics. It enables the work with live biological tissues and cells. Special electrochemical cells allow the work under physiological conditions.

The HEKA ELP 3 system combines electrochemical scanning probe techniques, such as SECM and SICM with optical microscopy, fluorecence imaging and calicium imaging. With a combination of these techniques new insights in the fields of biophysics, neurochemistry, electrophysiology and biochemistry can be gained.

The HEKA ElProScan is an integrated system, which allows control of all components, electrochemical experiments, microscope and optical detection system by one software. This guarantees perfect synchronization.

The HEKA ElProScan uses the Ultrapotentiostat PG 611 USB with external preamplifier for low current low noise recordings to even detect the smallest signal changes. For people who prefer to use our patch clamp amplifier EPC 10 USB, we have customized solutions.

The HEKA ElProScan features a positioning system with a large travel range and a resolution in the nanometer range. High precision is achieved by closed-loop linear encoders. The inverse microscope can be equipped with research-grade scientific cameras and illumination systems.

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.
