Conductivity cell

This comprises two electrodes and is used measure the conductance of a solution with the help of a conductimeter.

Cuvette
UV / Visible spectroscopic cell

A prismatic container with a specified path length made of glass, silica or polystyrene and used to carry out UV / Visible spectroscopic measurements.

Electrochemical cell

A device comprising two electrodes immersed in conducting solutions.
In the majority of the cases, the electrolyte solutions surrounding each electrode aredifferent and are separated to avoid chemical reactions.
So that the electrical current can circulate, the two solutions are connected by an electrolytic junction, e.g. a salt bridge.

Electrogravimetric cell

A particular cell used in a quantitative method of determining metal ions in aqueous solution based on the electrolytic reduction of the ions one by one.

Electrolysis cell

An electrochemical cell which is used to carry out oxidation reactions at the anode and reduction reactions at the cathode.

Galvanic cell

This is an electrochemical cell capable of producing electrical power.
Oxidation reactions at the anode release electrons spontaneously into the electric circuit.
These electrons are used at cathode to carry out reduction reactions.

Half cells

A galvanic cell consists of two half-cells of different potentials.

Infrared cells

Infrared cell for gases:

Infrared cell for solutions:

Potentiometric cell

Electrochemical cell used to measure the potential difference between two electrodes.
In general, there is a measuring electrode and a reference electrode.
The potential of the measuring electrode of measurement depends on the medium which surrounds it.
The common reference electrodes are the standard hydrogen electrode or, more practically, the calomel electrode.
Reference electrodes are separated from measuring electrodes by an electrolytic junction, e.g. a salt bridge.
In this way the conditions characteristic of the reference electrodes are not compromised by the components of the sample being measured.
