ALS ACCESSORIES FOR ELECTROCHEMISTRY
Electrochemical Cell for simultaneous investigations of optical properties and electrochemical redox reactions
Spectro-electrochemical Cells are used for simultaneous measurements of optical and electrochemical properties of a sample. We offer cuvettes for static applications and flow cells for continuous processes or changing electrolytes. A variety of different working and reference electrodes allows a flexible adaption to different measurement tasks.
RRDE-3A Rotator for measurements on rotating disk or ring-disk electrodes
With the RRDE-3A Rotator system measurements on rotating Disk- or Ring-Disk-Electrodes can be performed. The variation of the rotation rate allows to control the hydrodynamic properties and therefore to control the diffusion during voltametric measurements. A variety of materials as working electrodes are available, electrodes with exchangeable disks allow pre-processing of disks or the use of custom materials.
Portable hydrogen generator H2G1 and the Reversible Hydrogen Electrode (RHE) to generate Hydrogen and using the Reversible Hydrogen Electrode as a reference electrode.
The potential of electrochemical reactions is normalized versus the potential of a normal hydrogen electrode. The portable hydrogen generator H2G1 and the Reversible Hydrogen Electrode (RHE) offer an easy to use system to generate Hydrogen in the Reversible Hydrogen Electrode and to use it as a standard reference electrode.
Reference electrodes are used for the majority of electrochemical methods
Reference electrodes are needed for almost all kinds of electrochemical methods. ALS offers a variety of different electrodes for aqueous electrolytes and electrodes for organic media as well as a Reversible Hydrogen Electrode (RHE).
Non-aqueous reference electrodes are used for electrochemical methods in aprotic, organic solvents.

Working electrodes for different electrochemical applications like CV, LSV, and DPV
ALS offers a broad variety of working electrodes with different electrode materials and different dimensions. Micro electrodes for small sample volumes and fast measurements as well as mesh type electrodes with high surface area are available.
Lithographic electrodes for static ring-disk measurements, conductivity electrodes and Interdigitated Array (IDA) electrodes for experiments with small sample volumes
Due to the small dimensions, lithographically manufactured electrodes offer the possibility to measure small sample volumes with low detection limits. These electrodes are available for ring-disk experiments, conductivity measurements, and electrochemical experiments and sensors.
Counter or Auxiliary electrodes for a variety of applications like CV, LSV, or DPV
ALS offers a variety of counter electrodes made from different materials and in different sizes and shapes.
Voltammetry cells with different volumes and a variety of operation modes
The cells offer a variety of applications like CV, LSV, and DPV. Different sizes and volumes allow using small amounts of sample and safe expensive electrolytes. Electrolysis or electrochemical synthesis can be performed in the Bulk Electrolysis Cell. Flat samples dan be measured using the Plate Material Evaluating Cell.
QCM and eQCM cell for flexible use with different Quartz-Crystal-Microbalances
For measurements with Quartz-Crystal-Microbalances QCM or combined QCM and electrochemical methods, eQCM cells are needed. The ALS cells can be flexibly used as static and as a flow mode cell.
Durchflusszellen für die Detektion niedrigster Konzentration in Kombinationen mit HPLC, FIA (Flow Injection Analysis) sowie den Einsatz in der Biosensorik.
ALS offers different flow cells; cross flow cells creating a linear, laminar flow and radial flow cells with a central injection of the sample and a radiale outlet channel. The cells are used for detection in measurement systems like HPLC, FIA and microcapillary/microbore liquid chromatography.
Glassy Carbon products in a variety of different sizes and shapes, like films, plates, powders, and rods used as working or counter electrodes
Glassy Carbon consists of pure carbon with a very unique structure. Due to its outstanding properties it is often used for working or counter electrodes in different applications.
Useful accessories for working and reference electrodes
ALS offers a variety of useful accessories to build, maintain and take care of working and reference electrodes. Using Carbon paste or Silver/silver chloride ink working or reference electrodes can be set up, the polishing kit working electrode surfaces can be cleaned and polished; and the preservative vial prevents reference electrodes from drying out and cracking of the frit.
