{"product_id":"volumetric-flasks-cl-a-duran-y244-y244","title":"Volumetric flasks, cl. A, DURAN®, trapezoid, with stand. gr. joint, 25 ml","description":"\u003cp\u003eVolumetric flasks, class A, DURAN® are precision glass vessels for accurate preparation and dilution of standard solutions in volumetric analysis. This trapezoid model is fitted with a standard ground joint and offers a nominal capacity of 25 ml, supporting reliable volumetric work where class A tolerance is required. The DURAN® glass body provides the chemical resistance and thermal stability expected in routine laboratory glassware for aqueous and many organic media. Supplied as a pack of two pieces, the set is practical for parallel preparations or reserve stock at the bench. Each flask has a stated unit weight of 0,070 kg, reflecting a compact format suited to analytical balances and crowded fume hoods. The trapezoid profile aids stable standing during filling, mixing and temperature equilibration. These flasks from manufacturer Hirschmann integrate cleanly into existing volumetric glassware inventories used for titrimetry, standardisation and quantitative sample preparation. Clear class A marking and the ground joint interface support stoppering and transfer steps without compromising calibrated volume. Ideal for quality-control, teaching and research laboratories that rely on reproducible volumetric flasks for day-to-day analytical workflows.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/fr-fr\/collections\/volumetric-flasks\"\u003eVolumetric flasks\u003c\/a\u003e, in \u003ca href=\"\/fr-fr\/collections\/volumetric-glassware\"\u003eVolumetric glassware\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 2 pc(s)\u003c\/li\u003e\n\u003cli\u003eProduct type: Volumetric flask, class A\u003c\/li\u003e\n\u003cli\u003eGlass type: DURAN®\u003c\/li\u003e\n\u003cli\u003eShape: Trapezoid\u003c\/li\u003e\n\u003cli\u003eJoint: Standard ground joint\u003c\/li\u003e\n\u003cli\u003eCapacity: 25 ml\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Hirschmann","offers":[{"title":"2 pc(s) \/ 1 piece","offer_id":56186794934604,"sku":"Y244.1","price":46.35,"currency_code":"EUR","in_stock":true},{"title":"2 pc(s) \/ 6+ pieces","offer_id":56186794967372,"sku":"Y244.1","price":44.03,"currency_code":"EUR","in_stock":true},{"title":"2 pc(s) \/ 24+ pieces","offer_id":56186795000140,"sku":"Y244.1","price":41.72,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/Y239-01-1000Wx1000H_80cb75e2-75ff-49d3-ad77-a35e6442649d.jpg?v=1766501414","url":"https:\/\/www.luminixhealth.com\/fr-fr\/products\/volumetric-flasks-cl-a-duran-y244-y244","provider":"Luminix Health","version":"1.0","type":"link"}
