The 3 litre capacity gives heat-transfer media room to expand and contract during heating and cooling, supporting stable system pressure and reducing the risk of overflow at the main bath. Supplied as 1 pc with a net weight of 4,300 kg, the vessel is built for permanent placement beside circulating thermostats, process chillers and related laboratory temperature equipment. Integration is straightforward in setups that require external expansion volume outside the primary reservoir. This external expansion vessel from manufacturer Julabo is intended for professional laboratory and pilot-plant environments where reliable fluid management is essential during wide temperature swings. By separating expansion volume from the working bath, operators can maintain cleaner fluid handling and more consistent circuit behaviour over long runs. Originating from Germany, the unit fits general laboratory material inventories used with precision temperature-control systems. It is suited to routine installation on compatible Julabo-style hydraulic loops and comparable laboratory circulators that call for a dedicated 3 litre external expansion vessel.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/fr-fr\/collections\/bottle-accessories\"\u003eBottle accessories (pouring rings, dispensers, caps)\u003c\/a\u003e, in \u003ca href=\"\/fr-fr\/collections\/bottles-and-containers\"\u003eBottles \u0026amp; containers\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\u003eProduct type: External expansion vessel\u003c\/li\u003e\n\u003cli\u003eCapacity: 3 litres\u003c\/li\u003e\n\u003cli\u003eCountry of origin: Germany\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Julabo","offers":[{"title":"Default Title","offer_id":57998351237452,"sku":"8970832","price":858.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/idl-8970832.png?v=1783730798","url":"https:\/\/www.luminixhealth.com\/fr-fr\/products\/external-expansion-vessel-3-liters-for-presto-a30-a40-w40","provider":"Luminix Health","version":"1.0","type":"link"}
