Overall length is approximately 37 mm, and the sliding discs measure about 20 mm in diameter, creating the characteristic hantel-style profile that helps the bar track smoothly under magnetic drive. An Alnico 5 magnetic core is fully encapsulated in polytetrafluoroethylene (PTFE), giving universal chemical resistance for demanding wet-chemistry environments involving acids, bases and organic solvents. The inert PTFE overcoat minimises adhesion of residues and protects the magnet during routine laboratory use. Supplied in a pack of three pieces from manufacturer Bohlender, these dumbbell bars are suited to vessels in which the disc ends stabilise rotation and maintain consistent coupling to the drive magnet. Net weight is 0,013 kg. The combination of PTFE durability, Alnico 5 magnetism and the defined dumbbell dimensions supports reproducible stirring performance in research, quality-control and preparative workflows that require robust, chemically resistant magnetic stir bars.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-nl\/collections\/magnetic-stirring-bars\"\u003eMagnetic stirring bars\u003c\/a\u003e, in \u003ca href=\"\/en-nl\/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: 3 pc(s)\u003c\/li\u003e\n\u003cli\u003eLength: 37 mm\u003c\/li\u003e\n\u003cli\u003eSliding disc diameter: 20 mm\u003c\/li\u003e\n\u003cli\u003eMaterial: Polytetrafluoroethylene (PTFE)\u003c\/li\u003e\n\u003cli\u003eShape: Dumbbell\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.pdf?v=1788408693\" 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":57936092332364,"sku":"C35903","price":53.55,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/idl-C35903.png?v=1783730874","url":"https:\/\/www.luminixhealth.com\/en-nl\/products\/bola-dumbbell-shaped-magnetic-stirring-bars-l-37-mm-ptfe-coated","provider":"Luminix Health","version":"1.0","type":"link"}
