Clear DURAN® glass permits direct observation of process contents, while the wide NS 45\/40 joint offers a substantial connection interface for condensers, still heads and matching ground-joint accessories. The flask is supplied as 1 pc and has a weight of 0,154 kg, making it suitable for stable mounting in distillation frames and related apparatus. These round flasks from manufacturer Lenz address needs in environmental analysis as well as distillation and Soxhlet appliance configurations that specify a 250 ml round-bottom body with an NS 45\/40 joint. The combination of working volume and large joint size supports laboratory-scale set-ups requiring broader access or higher vapour throughput at the neck. Laboratories engaged in sample preparation, teaching and quality control can integrate the vessel into existing ground-joint assemblies while retaining standard joint compatibility across their glassware inventory.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/round-bottom-flasks\"\u003eRound-bottom flasks\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/beakers-and-flasks\"\u003eBeakers \u0026amp; flasks\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 1 pc\u003c\/li\u003e\n\u003cli\u003eProduct type: Round flask\u003c\/li\u003e\n\u003cli\u003eMaterial: DURAN® transparent glass\u003c\/li\u003e\n\u003cli\u003eCapacity: 250 ml\u003c\/li\u003e\n\u003cli\u003eGround joint: NS 45\/40\u003c\/li\u003e\n\u003cli\u003eWeight: 0,154 kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lenz","offers":[{"title":"1 pc \/ 1 piece","offer_id":56181318975820,"sku":"E594.1","price":65.05,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 6+ pieces","offer_id":56181319008588,"sku":"E594.1","price":61.8,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 24+ pieces","offer_id":56181319041356,"sku":"E594.1","price":58.55,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/HY49-01-1000Wx1000H_3eb62243-1910-4b92-ab7e-f38ea8b2ccf3.jpg?v=1766448263","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/round-flasks-duran-transparent-glass-e594-e594","provider":"Luminix Health","version":"1.0","type":"link"}
