{"product_id":"bola-boilling-stones-4-mm-500-gr-ptfe","title":"BOLA Boilling Stones, Ø 4 mm 500 gr PTFE","description":"\u003cp\u003eBOLA boiling stones are PTFE granules with a grain size of approximately 4 mm, designed to prevent splashing and uncontrolled bubble formation when a liquid medium is brought to the boil. The inert polytetrafluoroethylene surface supports smooth, even boiling behaviour and is suitable for a wide range of laboratory solvents and aqueous systems. Supplied as a 500 g pack in a resealable bag, the stones are easy to dose, store and reuse as needed in routine distillation, reflux and heating work. Manufactured by Bohlender, these boiling aids combine chemical resistance with a practical laboratory format. The net weight of the unit is 0,51 kg. Typical use includes addition of a small quantity of stones to flasks or vessels before heating to promote stable vapour release and reduce bumping. The PTFE construction keeps the stones chemically durable under common laboratory boiling conditions while remaining simple to handle and transfer between setups.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/de-be\/collections\/grease-boiling-stones-and-sealants\"\u003eGrease, boiling stones \u0026amp; sealants\u003c\/a\u003e, in \u003ca href=\"\/de-be\/collections\/tools-and-accessories\"\u003eTools \u0026amp; accessories\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 500 g\u003c\/li\u003e\n\u003cli\u003eProduct type: Boiling stones\u003c\/li\u003e\n\u003cli\u003eMaterial: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n\u003cli\u003eGrain size: approx. 4 mm\u003c\/li\u003e\n\u003cli\u003ePackaging: resealable bag\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bohlender","offers":[{"title":"Default Title","offer_id":57935033696588,"sku":"H97202","price":85.29,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/idl-H97202.png?v=1783730906","url":"https:\/\/www.luminixhealth.com\/de-be\/products\/bola-boilling-stones-4-mm-500-gr-ptfe","provider":"Luminix Health","version":"1.0","type":"link"}
