Fabricated from borosilicate glass 3.3 in DN 100 size, it provides a centre neck NS 29\/32, two angled side necks NS 29\/32 and one vertical side neck NS 14\/23, enabling flexible connection of dropping funnels, stirrer shafts and related accessories. Lid and base are held together by a clamping ring; a gasket or ground-joint grease prevents the ground surfaces from seizing and guarantees a dense seal. The geometry and solid wall thickness make the vessel pressure- and vacuum-resistant for safe laboratory operation. Typical applications include preparative reactions, distillations, evaporations and drying procedures involving solid or viscous materials, together with chemically and thermally demanding processes. This component from manufacturer Duran\/DWK Life Sciences is offered as a single piece ready for integration into flat flange assemblies.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/reaction-vessels-and-jacketed-vessels\"\u003eReaction vessels \u0026amp; jacketed vessels\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/beakers-and-flasks\"\u003eBeakers \u0026amp; flasks\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\u003eStorage temperature: Standard\u003c\/li\u003e\n\u003cli\u003eMaterial: Borosilicate glass 3.3\u003c\/li\u003e\n\u003cli\u003eNominal diameter: DN 100\u003c\/li\u003e\n\u003cli\u003eCentre neck: NS 29\/32\u003c\/li\u003e\n\u003cli\u003eEAN: 4032051030008\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/www.luminixhealth.com\/cdn\/shop\/files\/KG04_01_12_0860.pdf?v=1788393478\" 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":"DWK Life Sciences","offers":[{"title":"Default Title","offer_id":57997338837324,"sku":"243924702","price":364.27,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/47-M_D_image_243924702_1_f56aa35c-0c13-4513-91b8-6b9f248a1e5a.png?v=1783411668","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/duran-flat-flange-lid-4-standard-ground-necks-2-angled-1-parallel-1-center","provider":"Luminix Health","version":"1.0","type":"link"}
