Apera Instruments AI3103 Glass-Body pH Electrode for Small Samples

Features:

• Proprietary pH sensor technology and premium materials from Switzerland
• Low-resistance LabSen semi-micro cylindrical glass membrane, suitable for test tubes and small 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 with proprietary sensor technology and premium materials from Switzerland, LabSen 241-6 Glass-body Semi-Micro pH 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.
• 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 to enable ATC or manually input temperature to achieve temperature compensation.
