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.\u003c\/p\u003e \u003cp class=\"\" msonormal\u003eLabSen Glass Membrane - With a length of 180mm, a diameter of 3mm and low membrane resistance (\u0026lt;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.\u003c\/p\u003e \u003cp class=\"\" msonormal\u003eLong-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.\u003c\/p\u003e \u003cul\u003e \u003cli\u003epH sensor technology and materials from Switzerland\u003c\/li\u003e \u003cli\u003eCylindrical micro glass diaphragm (length: 180mm, ø3mm) with low resistance (\u0026lt;450MΩ) for improved response speed and measurement stability\u003c\/li\u003e \u003cli\u003eIdeal for measurements in NMR tubes and other thin vessels (minimum sample volume: 50μl, in micro container: 15μl)\u003c\/li\u003e \u003cli\u003eLong-life reference system that improves the stability of the reference electrode and extends the life of the electrode\u003c\/li\u003e \u003c\/ul\u003e \u003cp class=\"\" msonormal\u003eThe 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.\u003c\/p\u003e \u003cbr\u003e \u003cstrong\u003eTechnical Specifications:\u003c\/strong\u003e \u003ctable class=\"\" table_custom table-bordered table-condensed\u003e \u003ctbody\u003e \u003ctr\u003e \u003ctd\u003eMeasuring range\u003c\/td\u003e \u003ctd\u003e(0 ~ 14) pH\u003c\/td\u003e \u003ctd\u003eElectrolyte\u003c\/td\u003e \u003ctd\u003e3M KCl\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eRecommended operating temperature\u003c\/td\u003e \u003ctd\u003e(0 ~ 100)°C\u003c\/td\u003e \u003ctd\u003eStorage solution\u003c\/td\u003e \u003ctd\u003e3M KCl\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eShank material\u003c\/td\u003e \u003ctd\u003eLead free glass\u003c\/td\u003e \u003ctd rowspan=\"\"\u003eElectrode dimension\u003c\/td\u003e \u003ctd\u003eElectrode (Ø12×60) mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eReference system\u003c\/td\u003e \u003ctd\u003eLong Life\u003c\/td\u003e \u003ctd\u003eMeasuring tip (Ø3×180) mm\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eGlass membrane type\u003c\/td\u003e \u003ctd\u003eS\u003c\/td\u003e \u003ctd\u003eMicrovolume\u003c\/td\u003e \u003ctd\u003e50μl (15μl in micro container)\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eMembrane resistance\u003c\/td\u003e \u003ctd\u003e\u0026lt;450 MΩ (at 25°C)\u003c\/td\u003e \u003ctd\u003eConnection\u003c\/td\u003e \u003ctd\u003eBNC\u003c\/td\u003e \u003c\/tr\u003e \u003ctr\u003e \u003ctd\u003eDiaphragm\u003c\/td\u003e \u003ctd\u003eCeramic\u003c\/td\u003e \u003ctd\u003eCable\u003c\/td\u003e \u003ctd\u003eØ3mm×1m\u003c\/td\u003e \u003c\/tr\u003e \u003c\/tbody\u003e \u003c\/table\u003e \u003cp class=\"\" msonormal\u003e\u003cbr\u003e This electrode has a 6-month manufacturer's warranty.\u003c\/p\u003e","brand":"IDL","offers":[{"title":"1 piece","offer_id":56356565877068,"sku":"28APE190365","price":260.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/779-241-180.png?v=1767082281","url":"https:\/\/www.luminixhealth.com\/fr-be\/products\/labsen-241-180-micro-ph-electrode-for-nmr-tubes-and-small-samples-50l","provider":"Luminix Health","version":"1.0","type":"link"}
