The transparent DURAN® glass body allows continuous visual monitoring of contents during heating, reflux, concentration or extraction steps. A standardised NS 29\/32 joint ensures straightforward connection to condensers, adapters and other matching ground-joint components commonly used in environmental analysis and routine laboratory assemblies. Each flask is supplied as 1 pc and has a weight of 0,200 kg, making it practical for medium-scale distillation and sampling workflows. These round flasks from manufacturer Lenz fit established glassware trains for distillation and Soxhlet appliances as well as broader sampling and sample-preparation tasks. The 500 ml working volume supports typical laboratory batch sizes without unnecessary bulk, while the round form promotes even heat distribution when used with appropriate heating equipment. Suitable for research, teaching and routine analytical laboratories that require reliable DURAN® round flasks with NS 29\/32 connectivity for distillation and related preparative operations.\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: 500 ml\u003c\/li\u003e\n\u003cli\u003eGround joint: NS 29\/32\u003c\/li\u003e\n\u003cli\u003eWeight: 0,200 kg\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Lenz","offers":[{"title":"1 pc \/ 1 piece","offer_id":56181319074124,"sku":"E595.1","price":29.35,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 6+ pieces","offer_id":56181319106892,"sku":"E595.1","price":27.88,"currency_code":"EUR","in_stock":true},{"title":"1 pc \/ 24+ pieces","offer_id":56181319139660,"sku":"E595.1","price":26.42,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/HY49-01-1000Wx1000H_d2775722-9a3f-40d6-849c-0f15df533715.jpg?v=1766448264","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/round-flasks-duran-transparent-glass-e595-e595","provider":"Luminix Health","version":"1.0","type":"link"}
