{"product_id":"bola-egg-shaped-magnetic-stirring-bars-l-70-mm-20-mm-ptfe-coated","title":"BOLA Egg-Shaped Magnetic Stirring Bars, L 70 mm Ø 20 mm PTFE-coated","description":"\u003cp\u003eBOLA egg-shaped magnetic stirring bars measuring approximately 70 mm in length and 20 mm in diameter incorporate a magnetic core of Alnico 5 fully encased in a polytetrafluoroethylene (PTFE) coating. This ellipsoid geometry is optimised for use in round-bottom flasks according to DIN 12 348 with a nominal volume of 10000 ml, promoting smooth and efficient mixing. The PTFE overcoat confers universal chemical resistance, allowing the stirring bar to withstand contact with a broad spectrum of laboratory reagents and solvents without degradation. Each unit is supplied as one piece and has a net weight of 0,06 kg. These BOLA stirring bars from manufacturer Bohlender support routine magnetic stirring tasks in analytical, synthetic and quality-control laboratories. The inert surface reduces sample carry-over and facilitates thorough cleaning after use. With a diameter of 20 mm and an egg-shaped profile, the bar maintains stable coupling to the drive magnet while generating an effective vortex even in larger vessels. The combination of robust Alnico 5 magnetism and chemically inert PTFE makes this accessory a practical choice for demanding wet-chemistry workflows.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/magnetic-stirring-bars\"\u003eMagnetic stirring bars\u003c\/a\u003e, in \u003ca href=\"\/en-fr\/collections\/stirring-shaking-and-mixing\"\u003eStirring, shaking \u0026amp; mixing\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\u003eLength: approx. 70 mm\u003c\/li\u003e\n\u003cli\u003eDiameter: 20 mm\u003c\/li\u003e\n\u003cli\u003eShape: Ellipsoid\u003c\/li\u003e\n\u003cli\u003eMaterial: Polytetrafluorethylen (PTFE)\u003c\/li\u003e\n\u003cli\u003eMagnetic core: Alnico 5\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/www.luminixhealth.com\/cdn\/shop\/files\/KG09_01_01_0010_EN.pdf?v=1790255777\" target=\"_blank\" rel=\"noopener noreferrer\" style=\"display:inline;vertical-align:middle\" title=\"Technical sheet PDF\" aria-label=\"Technical sheet PDF\"\u003e\u003cimg class=\"sds-icon\" src=\"https:\/\/img.icons8.com\/color\/48\/pdf.png\" alt=\"PDF\" width=\"18\" height=\"18\" style=\"width:18px;height:18px;max-width:18px;margin:0;padding:0;display:inline;vertical-align:middle;border:0;\"\u003e\u003c\/a\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bohlender","offers":[{"title":"Default Title","offer_id":57936092070220,"sku":"C35816","price":23.52,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/idl-C35816.png?v=1783730872","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/bola-egg-shaped-magnetic-stirring-bars-l-70-mm-20-mm-ptfe-coated","provider":"Luminix Health","version":"1.0","type":"link"}
