Their precise scaling makes them particularly suitable for titrimetric purposes. The amount of liquid required for titration, but previously unknown, can be read off very accurately after the reaction has been completed. Adjustment is made to drain (''Ex'') for + 20 °C reference temperature. This means that the quantities can be taken exactly according to the scale, since the adhesion of the liquid to the glass was taken into account during calibration. The tolerances for the volume correspond to the error limits of ISO and DIN. DURAN® burettes are available with glass or PTFE keys. Unlike glass keys, PTFE keys do not have to be greased, which simplifies work in the laboratory.\u003cbr\u003e\u003cstrong\u003eFeatures and Benefits:\u003c\/strong\u003e\u003cbr\u003e\u003cul\u003e\n\u003cli\u003eComplies with ISO 385\u003c\/li\u003e\n\u003cli\u003eCalibration is based on the poured out volume (“Ex”) at a + 20 °C reference temperature.\u003c\/li\u003e\n\u003cli\u003eWith circular ring graduations\u003c\/li\u003e\n\u003cli\u003eThe quantity of liquid required for titration, which is unknown beforehand, can be precisely read off once the reaction is complete.\u003c\/li\u003e\n\u003cli\u003eWith Schellbach stripe\u003c\/li\u003e\n\u003cli\u003eThe volume content tolerances conform to accuracy class AS\u003c\/li\u003e\n\u003cli\u003ewaiting time: 30 seconds\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003eApplication: Titration, Volumetric measurement, Measurement analysis","brand":"IDL","offers":[{"title":"Case of 2","offer_id":56414724718924,"sku":"243292704","price":234.18,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/47-M_D_image_243293306_1.png?v=1767486509","url":"https:\/\/www.luminixhealth.com\/fr-fr\/products\/duran-burette-class-as-schellbach-stripe-and-glass-key-coc-batch-certificat","provider":"Luminix Health","version":"1.0","type":"link"}
