Description
The LabSen® 241-180 Micro pH Electrode from Apera Instruments is manufactured using proprietary Swiss sensor technology and materials. It is particularly suitable for use with NMR tubes due to its long tip, but can also be used to measure small sample volumes (min. 50μl) in other thin tubes. With a matching micro container from Apera Instruments (sold separately), samples as small as 15μl can be measured.
LabSen Glass Membrane - With a length of 180mm, a diameter of 3mm and low membrane resistance (<450MΩ), the cylindrical micro glass membrane enables fast and reliable measurements in small containers such as NMR tubes. The electrode can be used at temperatures of up to 100°C.
Long-life reference system - The LabSen 231-180 micro pH electrode uses a long-life reference system consisting of a glass tube, AgCl and a reference silver wire. The top of the thin glass tube is filled with cotton, which prevents the reaction between AgCl and electrolyte when the temperature changes. It improves the stability of the reference electrode and extends the life of the electrode.
- pH sensor technology and materials from Switzerland
- Cylindrical micro glass diaphragm (length: 180mm, ø3mm) with low resistance (<450MΩ) for improved response speed and measurement stability
- Ideal for measurements in NMR tubes and other thin vessels (minimum sample volume: 50μl, in micro container: 15μl)
- Long-life reference system that improves the stability of the reference electrode and extends the life of the electrode
The electrode uses a BNC connector that is compatible with all pH meters that use BNC connectors, such as Apera Instruments PH850, PC850, PH8500, PC8500, PH700, PH910, PC910, PH950, PC950,PH800, PH800, PC800, PH820 and PC820. A temperature sensor is not integrated. For automatic temperature compensation, a separate temperature sensor (e.g. Apera Instruments MP500) is required, or the temperature must be entered manually.
