The spherical body promotes even heating and efficient mixing of liquids under reflux or reduced pressure, while the clear borosilicate glass allows continuous visual monitoring of the contents. A precision-ground NS 29\/32 neck ensures reliable, leak-resistant connections to condensers, adapters and other jointed glassware. Supplied as a single piece weighing 0,55 kg, the flask is suited to routine preparative work where chemical resistance and thermal stability matter. These vessels from manufacturer Lenz fit standard heating mantles, oil baths and clamps used in distillation trains and sample-concentration setups. Transparent DURAN® construction helps operators track colour changes, boiling behaviour and phase separations without interrupting the process. Ideal for analytical and preparative laboratories that require robust round-bottom flasks with defined joint geometry for reproducible assembly of multi-piece glass apparatus.\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 29\/32\u003c\/li\u003e\n\u003cli\u003eWeight: 0,55 kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lenz","offers":[{"title":"1 pc \/ 1 piece","offer_id":56181319467340,"sku":"E599.1","price":71.95,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 6+ pieces","offer_id":56181319500108,"sku":"E599.1","price":68.35,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 24+ pieces","offer_id":56181319532876,"sku":"E599.1","price":64.76,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/HY49-01-1000Wx1000H_7ec2389d-210b-4f82-b487-1ce511be9b1f.jpg?v=1766448266","url":"https:\/\/www.luminixhealth.com\/en-be\/products\/round-flasks-duran-transparent-glass-e599-e599","provider":"Luminix Health","version":"1.0","type":"link"}
