    • Rod / disc (6 mm diameter).
    • Thin film deposited on flat substrate (using a wire clip).
    • Membrane (using a wire clip).

Photo-electrochemical single & double sided cells

photoelectrochemical-double-sided-cells

These are horizontally mounted single and double chamber photoelectrochemical cells. These units allow for a variety of methods in order to carry out measurements in 2 or 3 electrode settings.

The structure is gas-tight with gas inlets and outlets that can be used to bubble the solution and vent gases from the chamber.

Typical applications include: basic photochemistry, photolysis water splitting, photoinduced charge separation and photocorrosion.

Optical fiber spectro-electrochemical flow cell

optical-fiber-spectro-electrochemical-cell
This is a horizontally mounted, multi-purpose spectroelectrochemical cell designed to be coupled to a light source and spectrometer (UV-Vis, NIR, IR) via fiber optics. It is capable of obtaining electrochemical and spectral information from a liquid sample or thin-film in systems where a change in the applied potential causes a variation in the observed spectrum.

Spectroelectrochemical cells are used to study the relationship between absorbance / transmittance and electrochemical potential, thereby, they can effectively monitor the optical changes of electrochromic materials in real time.

In-situ spectral acquisition is readily obtained for the detection, identification and characterization of short-lived electrochemically generated species / intermediates, which in turn derives to a detailed investigation of the mechanisms of redox reactions.

Gas Diffusion Electrode X-Ray diffraction electrochemical flow cell

gas-diffusion-x-ray-diffraction-electrochemical-cell

A GDE XRD electrochemical cell is used to efficiently screen and validate GDEs (Gas Diffusion Electrodes) for metal-air batteries, water electrolysis and alkaline fuel cells.

It also enables acquiring X-ray diffraction measurements in-situ.

It is used as an aspirating, thermodynamic electrical analysis reference unit which simulates the Janus arrangement of a GDE in a metal-air battery: one side is freely exposed to the gas and the other side is wetted by the electrolyte.

Electrolyte-gated transistor bottom mount electrochemical cell

electrolyte-gated-transistor-electrochemical-cell

Fixed solution electrochemical cell built to measure the characteristics of an electrolyte-gated (solution-gated) transistor using a liquid or gel electrolyte.

The fabrication of a measured transistor sample can be realised on a rigid or flexible flat substrate (not included in the system) having a conductive thin film source, as well as drain, and a layer of conductive or semi-conductive channel material.

The structure is gas-tight and can be used by bubbling an inert gas through the electrolyte to remove or exclude contaminants such as oxygen and water.

Standard, small, large and double-tank etch cells

double-tank-etch-cells
A common application of electrochemically etched cells is the preparation of a nanocrystalline porous silicon layer on a single crystal Si wafer.

For example, a double-tank etching cell is generally used to produce a porous Si thin film by anodization. The process of forming porous Si is performed in a constant manner by applying a current between two platinum electrodes.

The main process parameters are: current density and etching time. In this cell structure, no additional metal contact needs to be made on the Si-wafer to ensure electrical contact.

Other applications include electropolishing of Si substrates, electrodeposition, and electrochemical characterization.

Bulk electrolysis basic & two-compartment cells

bulk-electrolysis-basic-cells

Standard and two-chamber high-capacity electrolytic cells (also known as constant-potential or controlled-potential coulometric cells) with basic construction.

The structure is gastight.

Typical applications for bulk electrolysis include complete oxidation or reduction of materials, complete synthesis of products by electrochemical processes (small-scale electroforming and electro-separation), partial oxidation or reduction of compounds to alter the proportion of oxidized and reduced species and the study of the complexity of reaction mechanisms (E.g. coupling reactions).

Spectro-electrochemical flow cells

spectro-electrochemical-cells

These are horizontally mounted, multi-purpose spectroelectrochemical cells designed to be utilized with a spectrometer (UV-Vis, or IR). They are capable of obtaining electrochemical and spectral information from a liquid sample or thin-film in systems where a change in the applied potential causes a variation in the observed spectrum.

Spectroelectrochemical cells are used to study the relationship between absorbance/transmittance and electrochemical potential, thereby, they can effectively monitor the optical changes of electrochromic materials in real time.

In-situ spectral acquisition is readily obtained for the detection, identification and characterization of short-lived electrochemically generated species / intermediates, which in turn derives to a detailed investigation of the mechanisms of redox reactions.

Raman Electrochemical Flow Cell

raman-electrochemical-cell
The cell structure combines two traditional scientific techniques, such as electrochemical and Raman spectroscopy, to obtain in-situ chemical data regarding reactions occurring during electrochemical experiments.
 

The structure is gas-tight and can be used by bubbling an inert gas through the electrolyte to remove or exclude contaminants such as oxygen and water (in an external repository).

This system can be used to track dynamic phenomena such as proton concentration variations near the surface while oxidation and reduction reactions take place at the working electrode. In addition, it can also be utilized to identify materials such as carbon, metal oxides, polymers and electrolytes, as well as to determine their structure and distribution. Various metals are appropiate for this assembly as supplementary electrodes, including platinum, gold and silver.

Photo-electrochemical H-cells

photo-electrochemical-H-cells

These are horizontally mounted double chamber photo-electrochemical H-Cells used to study thin film photoanodes and cathodes simultaneously. These units allow for a variety of methods in order to carry out measurements in 2 or 3 electrode settings.

Similarly, and in the case of the photoelectrochemical flow H-Cell, the structure is liquid-tight with electrolyte inlets and outlets, which allow solution flow as well as the emptying of the reaction product from each of the two distinct chambers.

Typical applications include: basic photochemistry, photolysis water splitting, photoinduced charge separation, photocorrosion and CO2 reduction.
