Messzelle

Messzelle is a compact measurement cell used in chemical and electrochemical experiments to hold samples and connect to analytical instruments. The name combines messen (to measure) and Zelle (cell), and in practice denotes a modular chamber designed for precise measurements under controlled conditions.

Typical Messzelle designs include a sealed chamber with electrical terminals for a working, reference, and counter electrode, or a two-electrode arrangement. Volumes range from tens to hundreds of microliters, with options for temperature control, seals, and, in some models, optical access for spectroscopic monitoring.

Operation involves interfacing the cell with a potentiostat or galvanostat. By applying a defined potential or current, the device yields current or potential data used to deduce concentrations, kinetics, or diffusion properties. Careful calibration and electrode conditioning are essential for reproducible results.

Applications include electroanalysis, corrosion studies, sensor development, and educational demonstrations. The modular nature of Messzelle systems allows rapid substitution of electrolytes, samples, or electrodes without reassembling a larger setup.

In terminology, Messzelle appears mainly in German-language manuals and some instrument catalogs; in English, the component is typically described as a measurement cell or electrochemical cell module. The concept parallels standard electrochemical cells and microfluidic reaction chambers.
