Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 223 Glass Combination pH/temp. Electrode is designed for low ion concentration samples and titration as well as general water solutions. The electrode is compatible with TRIS buffer solutions. LabSen S-type spear glass membrane - low resistance and high firmness, rendering fully stabilized readings in 15 to 30 seconds, and is yet 10 times stronger than traditional glass membranes, highly resistant to general impact, eliminating the chance of accidental breakage while inserting into food samples. Movable Sleeve Junction - easy to clean, especially suitable for low ionic strength solutions, emulsions, and suspensions. The infiltration rate of the electrolyte can be adjusted by the tightness of the sleeve. Swiss patented pH/temperature combination structure - increases the temperature response time by 40% compared to a conventional isolated built-in thermistor, accelerating ATC and the stabilization process. Compatible with all Apera Instruments meters with BNC and RCA connectors such as PH910, PH9500, PH850, PC8500, and PH820. May NOT work with other brands' meters because the thermistor might be incompatible. (1 per EA )

Built with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 851-1 Glass-body pH Electrode is designed for pH measurement of viscous samples such as skincare products, cosmetics, and coatings. Silver Ion Trap Reference System+Protelyte Electrolyte - The LabSen 851-1 pH electrode adopts a Silver Ion Trap reference system and Protelyte reference solution, minimizing junction clogs. LabSen conical glass membrane - large surface area rendering fast response, and is 10 times stronger than traditional glass membranes, saving the electrode from accidental damage. The electrode uses a BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera MP500) to enable ATC or manually input temperature to realize temperature compensation. (1 per EA )

LabSen® 231 Combination pH Electrode for Wastewater, Suspension, and Emulsion Backed by proprietary Swiss sensor technology and materials, the LabSen 231 Combination pH Electrode is ideal for testing emulsion, suspension, wastewater, and samples containing protein and sulfide. Its 2-pore double junction structure and solid electrolyte make it hard to be contaminated and highly resistant to compression. Long-Life Reference System – The LabSen 231 pH electrode adopts a long-life reference system, which is composed of a glass tube, AgCl and a reference silver wire. The top end of the slim glass tube is stuffed with cotton, which prevents the reaction between AgCl and electrolyte when temperature changes. It improves the stability of reference electrode and prolong the service life of the electrode. Polymer Electrolyte – The polymer electrolyte is in direct contact with test samples. The anti-pressure capacity can reach up to 6 bars, making it ideal for testing suspension and wastewater. Special Glass Membrane – The LabSen 231 pH electrode adopts a Half-Balll glass membrane, which is highly resistent to general impact (the traditional glass bulb membrane is a lot more fragile), and can be tested in high temperature samples (up to 176°F). The electrode is backed up with a 6-month warranty by Apera Instruments. (1 per EA )

Glass-body pH/Temp. Electrode for Strong Alkali and High Salinity Solutions (1 per EA )

Backed by proprietary sensor technology and premium materials from Switzerland, Apera LabSen 841 Glass pH Electrode is designed for high-precision pH measurement of strong alkaline solutions (10-14 pH). LabSen HA Glass Membrane – better accuracy and repeatability in strong alkaline solutions (10 to 14 pH), minimizing alkaline errors. Built tough – The hemispherical glass membrane is 10 times stronger than traditional glass membranes, highly resistant to general impact, saving the electrode from accidental damage. Silver Ion Trap Reference System – On top of the Long-Life reference system, a silver ion trap is added to further prevent junction clog. The electrode uses a standard BNC connector, compatible with any pH meters that use BNC connectors. No temperature sensor is built-in. Users need to have a separate temperature probe (ex: Apera Instruments MP500) to enable ATC or manually input temperature to realize temperature compensation. (1 per EA )
