LabSen Micro pH Electrode for NMR Tubes

Apera Instruments, AI3161, LabSen 241-180 Micro pH Electrode for NMR TubesFeatures:Proprietary pH sensor technology and premium materials from SwitzerlandLow-resistance LabSen® 180mm x 3mm micro cylindrical glass membrane, ideal for NMR tubes and other slim containers (minimum sample volume: 50 microliters)Long-Life Reference System, improving the stability of the reference and extends the electrode's service lifeBuilt with proprietary sensor technology and premium materials from Switzerland, Apera LabSen 241-180 Glass Micro pH Electrode is designed for micro-volume samples in slim containers such as NMR tubes (minimum sample volume: 50 microliters).LabSen Glass Membrane - LabSen 241-180 pH electrode adopts an ultra-long 180mm micro cylindrical glass membrane (3mm), making NMR tube pH measurement easier than ever. And it can be tested at high-temperature up to 212°F. The low-resistance membrane (<450MΩ) helps you quickly get a fully stabilized reading.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 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 to enable ATC or manually input temperature to achieve temperature compensation.
