The Ion-Selective Electrodes (ISE) category brings together products designed to measure physical, chemical or mechanical properties and convert observations into data that can be compared, documented and acted upon. In a working laboratory, the category supports more than a single task because it connects preparation, handling, operation and routine maintenance around the same method.
Instrument suitability, calibration and sample preparation all influence whether a result is repeatable and meaningful. A well-matched setup balances measurement range, accuracy and resolution, sample type, and sensor or fixture compatibility, helping the laboratory avoid unnecessary rework, difficult cleaning or premature replacement.
A sound measurement workflow links representative sampling, suitable sensors or fixtures, calibration or verification, controlled testing and reliable recording of results. Looking at the full sequence makes it easier to identify the correct accessories and consumables before the equipment is put into service in research, quality assurance, manufacturing, environmental, education and service laboratories. As part of the Analytical Measurement & Testing Equipment range, these products can be selected with the equipment and consumables used before and after this stage.
Our Ion-Selective Electrodes (ISE) range
Our collection covers when special reagents to use an ion selective electrode, a combination and a mono-ise, these electrodes measure any ion, and calibration frequency for ise, giving laboratories practical choices for routine work and more specialised applications.
When special reagents to use an Ion Selective Electrode
Most ISE measurements require an Ionic Strength Adjustor (ISA) to ensure a constant background ionic strength, allowing the electrode to measure activity accurately as concentration. Before ordering, compare measurement range, accuracy and resolution, and sample type. A product that fits the complete workflow will generally be easier to validate, maintain and reorder. Within the wider method, these products help laboratories produce consistent measurements while keeping calibration, sample handling and documentation aligned. They should be reviewed together with associated consumables, accessories and cleaning requirements.
A combination and a mono-ISE
A combination ISE, like the WTW F 800 BNC, contains both the sensing and reference electrodes in one probe, while a mono-ISE requires a separate reference electrode to complete the circuit. Key differences are usually found in accuracy and resolution, sample type, and sensor or fixture compatibility. These details affect day-to-day usability as much as the main performance specification. Within the wider method, these products help laboratories produce consistent measurements while keeping calibration, sample handling and documentation aligned. They should be reviewed together with associated consumables, accessories and cleaning requirements.
These electrodes measure any ion
Each ISE is specifically engineered with a membrane sensitive to one particular ion (e.g., Fluoride, Chloride, or Sodium); you must select the electrode that matches your target analyte. The most suitable format depends on sample type, sensor or fixture compatibility, and calibration requirements. Laboratories should also confirm how the product will be prepared, used, cleaned or disposed of between runs. In practice, this supports efforts to produce consistent measurements while keeping calibration, sample handling and documentation aligned. It also gives staff a clearer and more repeatable procedure when multiple users or shifts share the same equipment.
Calibration frequency for ISE
For laboratory-grade results, ISE sensors should be calibrated daily or before each measurement series using at least two standards that bracket the expected concentration range. The most suitable format depends on sensor or fixture compatibility, calibration requirements, and data handling. Laboratories should also confirm how the product will be prepared, used, cleaned or disposed of between runs. Within the wider method, these products help laboratories produce consistent measurements while keeping calibration, sample handling and documentation aligned. They should be reviewed together with associated consumables, accessories and cleaning requirements.
