The versatile sensor portfolio ensures the perfectly suited sensor for every application, a match that greatly extends the lifetime of the products. InLab® Sensor Technology Proven Reliability The variety of electrochemical sensors is as diverse as the applications they are used for. Only the right combination of high-quality materials, tried-and-trusted technologies, and the shape of the membrane make a sensor perfectly suited for a specific application. Membrane Glass - The membrane is the pH sensing part of the sensor. Its shape and glass composition are optimized to assure best results for different applications. HA – High alkali glass with low alkali error for high pH values and high temperatures. U – Universal glass for standard applications and small membranes. A41 – highly robust glass particularly resistant to harsh chemicals, suitable for high temperatures. LoT – Low temperature glass with low resistance. Suitable for samples with low temperatures and low ion concentrations. HF – Hydrofluoric acid resistant glass for samples containing hydrofluoric acid (up to 1 g/L). Wetting Cap - Ready to use at any time, easy to handle and spill proof. Perfect to keep the glass membrane hydrated. Junction - The junction is the connection between the reference electrolyte and the sample. Temperature Probe - Temperature compensation included! The pH value of a solution is temperature dependent. Thus, the temperature should be measured with every pH value. Ceramic Junctions - For general applications. Sleeve Junctions - For fast results, best in dirty samples. Open Junctions - For easy cleaning and clogfree measurement. SafeLock™ - For refillable sensors: easy to open for measurement, perfectly sealed for storage and transport. Reference Electrolyte - Liquid electrolytes are typically used for general applications and provide fast results. Polymer or gel electrolytes stand for low maintenance. Shaft Material - The sensor robustness is dependent on the right shaft material. Glass is highly chemically resistant and allows for measurements at high temeratures. When mechanical robustness is key, plastic is the preferred material Reference System - Provides a stable potential against which the pH dependent potential can be compared. ARGENTHAL™ with silver ion trap - For silver ion free electrolyte. No clogging of the junction due to sulfide or protein containing samples or TRIS buffers. SteadyForce™ - Pressurized (3 bar) electrolyte ensures electrolyte flow even in viscous samples and guarantees highly reproducible results. ISM Intelligent Sensor Management - Every ISM marked sensor offers data security and easy handling. Secure and efficient - Calibration data and sensor ID are automatically transferred to the meter. Always up to date - New calibration data are stored in the sensor. Backup certificate guaranteed - Initial factory calibration is stored in the sensor. Conclusive calibration history - The last five calibrations are stored in the sensor. Easy lifetime monitoring - The maximum temperature that the sensor has been exposed to is monitored automatically. General Purpose pH Glass Electrodes Time is Precious Sensors for Fast Results Liquid filled electrodes are reliable workhorses, constructed for efficient pH measurements in daily laboratory use of a wide application range. For more complex sample matrices like emulsions or biological media, electrodes with a sleeve junction are recommended. Electroplating is a common technique used to coat metals in order to add desired properties to them. Strong acids and bases are needed for this process and the robust HA glass of the InLab Routine Pro-ISM is ideal for this application as it covers the whole pH range with an extremely low alkali error.

Specialist Low Temperatures pH Glass Electrodes

Pure Performance Low Temperatures and Ionic Strenght

A special membrane glass and a large membrane surface are typical characteristics for sensors suited for measuring in samples at low temperatures or with low ion concentrations. One of the key areas of application is the measurement of pure water at various levels of purity.

Pure water is a key ingredient in every pharmaceutical production process. The InLab Pure Pro-ISM convinces with a strong performance in weak ionic strength samples.

Reach New Depths Long Sensors

The deeper the container, the more difficult it gets to reach the sample. Sensors with especially long and robust shafts are required for proper pH measurements in very deep or narrow containers

From the chalk board to experimental reactions to ultimately the final formulation. The extra-long InLab Reach sensors are a solid companion during the whole scale-up process in the pilot production

Combined Ion-Selective Electrodes

Catch Them All Combined Ion-Selective Electrode

As various as the range of different ions, as various is the selection of ion-selective electrodes (ISE). The special Click & Clear™ junction allows for an optimal contact of the electrolyte solution and the sample. With the dedicated solutions the sample can be optimally prepared for successful measurement of ion concentration

Quick cleaning and stable measurements The brilliant Click & Clear™ press mechanism allows for quick cleaning and ensures stable readings even in difficult samples

Complete solution Combined ion-selective electrodes have an integrated reference system. No additional reference electrode is needed.
