Manufactured to ISO 385 and adjusted for delivery (TD, Ex), this class A burette meets demanding accuracy requirements for quantitative analysis. The upper end features a funnel-shaped opening that simplifies and secures filling, reducing the need for separate funnels and lowering spillage risk. A straight polytetrafluoroethylene (PTFE) stopcock offers chemical resistance together with smooth, reliable flow control during titrant addition. With a nominal volume of 50 ml the instrument is a versatile choice for routine acid–base, redox and complexometric titrations in education, research and industrial quality control. The single-piece unit has a net weight of 0,170 kg and is supplied by manufacturer Labbox. A batch certificate is available free of charge for download, supporting traceability and documentation. Funnel top, PTFE key and class A performance together enable efficient, reproducible work with common aqueous laboratory reagents.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-nl\/collections\/burettes\"\u003eBurettes\u003c\/a\u003e, in \u003ca href=\"\/en-nl\/collections\/volumetric-glassware\"\u003eVolumetric glassware\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 1 pc\u003c\/li\u003e\n\u003cli\u003eNominal volume: 50 ml\u003c\/li\u003e\n\u003cli\u003eAccuracy class: A\u003c\/li\u003e\n\u003cli\u003eStopcock material: PTFE\u003c\/li\u003e\n\u003cli\u003eFilling aid: funnel opening\u003c\/li\u003e\n\u003cli\u003eEAN: 8434868011489\u003c\/li\u003e\n\u003cli\u003eGTIN: 08434868011489\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/www.luminixhealth.com\/cdn\/shop\/files\/pds-82.pdf?v=1788411819\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"Technical sheet PDF\" aria-label=\"Technical sheet PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Labbox","offers":[{"title":"Default Title","offer_id":57934428504396,"sku":"BURTF50001","price":34.01,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/idl-BURTF50001.png?v=1783731265","url":"https:\/\/www.luminixhealth.com\/en-nl\/products\/burette-with-ptfe-straight-stopcock-and-funnel-top-class-a-50-ml","provider":"Luminix Health","version":"1.0","type":"link"}
