The round-bottom design distributes heat evenly during boiling, reflux and concentration steps common in environmental analysis and sample preparation. Clear glass walls give an unobstructed view of reaction mixtures, solvent levels and precipitate formation throughout the process. Delivered as one unit with a mass of 0,50 kg, the flask integrates readily into existing jointed glassware trains. Manufactured by Lenz, it is intended for laboratories that need durable borosilicate vessels with a larger neck diameter for higher vapour throughput or easier charging of solids. The NS 45\/40 joint geometry supports stable, vacuum-compatible assemblies used in Soxhlet setups, rotary-evaporator receivers and multi-neck distillation configurations. Transparent DURAN® construction combines chemical resistance with optical clarity for everyday preparative and analytical work requiring a 2-litre round flask.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/round-bottom-flasks\"\u003eRound-bottom flasks\u003c\/a\u003e, in \u003ca href=\"\/en-be\/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: 2000 ml\u003c\/li\u003e\n\u003cli\u003eGround joint: NS 45\/40\u003c\/li\u003e\n\u003cli\u003eWeight: 0,50 kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lenz","offers":[{"title":"1 pc \/ 1 piece","offer_id":56181319565644,"sku":"E600.1","price":79.1,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 6+ pieces","offer_id":56181319598412,"sku":"E600.1","price":75.15,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 24+ pieces","offer_id":56181319631180,"sku":"E600.1","price":71.19,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/HY49-01-1000Wx1000H_c6334973-cb86-439a-b33f-e5bcf2de3369.jpg?v=1766448267","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/round-flasks-duran-transparent-glass-e600-e600","provider":"Luminix Health","version":"1.0","type":"link"}
