LabSen 243-6 Refillable pH/Temp. Electrode for Test Tubes and Small Samples (>0.2mL)

• Proprietary pH sensor technology and premium materials from Switzerland
• Low-resistance LabSen semi-micro cylindrical glass membrane, suitable for semi-micro samples (>0.2mL)
• Smallest test volume is 60µL with the use of the semi-micro container (sold separately)
• Long-Life Reference System, improving the stability of the reference and extends the electrode's service life
• No more air bubbles inside the glass membrane thanks to the Swiss blue gel electrolyte.
• Built-in temperature sensor (30KΩ thermistor)

Built with proprietary sensor technology and premium materials from Switzerland, LabSen 243-6 Glass-body Semi-Micro pH/Temp. Electrode is designed for test tubes and small-volume samples (>0.2mL).

LabSen S-type semi-micro glass membrane - 100mm in length and 6mm in diameter, low membrane resistance (<350MΩ), making reliable small-volume (>0.2mL) pH measurement easier than ever, and can be tested in high-temperature samples (up to 212°F).

Long-Life Reference System - 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 the temperature changes. It improves the stability of the reference system and extends the electrode's service life.

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.
