Product news

Metrohm provides a wide range of electrodes for almost any application. But how can you find out which one is best suited for your sample/application?

To help you with this question Metrohm offer you charts listing specific samples/applications and the Metrohm electrodes best suited for them. On offer are «Electrodes for pH-measurement» and «Electrodes for titration». The charts are available as A4 sheets and A2 posters. Please find the order numbers below and get your own free copy from your Metrohm sales representative. The charts will also be included in the next issue of our MetrohmInfo.

ElectrophoresisElectrophoresis equipment is used to separate mixtures of protein, DNA or RNA, based on their electric charge, size and other physical characteristics, by passing them through a medium such as a polyacrylamide gel, an agarose gel or a capillary tube. Electrophoresis equipment includes horizontal and vertical gel electrophoresis chambers, isoelectric focusing systems, 2D electrophoresis and capillary electrophoresis instruments. Precast gels with a gradient can be used or gels can be hand cast. Samples are run alongside ladders or markers to identify the approximate size of a molecule. Separated proteins and nucleic acids in the gel can be stained or probed with fluorescent markers and then imaged and detected using gel documentation instruments, transilluminators, densitometers and scanners.

Other meters can also measure the conductivity or dissolved oxygen content of a solution. pH meters, specific ion meters, conductivity meters and dissolved oxygen meters can come as benchtop or portable equipment. A meter’s electrodes can be replaced with easy to clean electrodes or electrodes for difficult media. pH, ion and conductivity meters are typically used in life science research, pharmaceutical testing, food and beverage, environmental and water analysis. Find the best pH meters and electrodes in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.pH and Conductivity MetersIon and pH meters, used for electrochemical techniques and measurements, measure the concentration of specific ions using electrodes (probes) and a meter. Features of ph and ion meters to consider include temperature compensation, auto-calibration, adjustable resolution, measurable range and accuracy. Meters can be handheld, portable, benchtop and modular.TitrationTitration is an analytical technique for determining substance concentration in a solution. For titration consider a manual or automated system, volumetric or coulometric reagent addition and indication by a potentiometer, spectrometer, turbidometer or by the Karl Fischer method. Other features of titration to consider include burettes, reagents, concentration range, reaction time and autosamplers.
