{"product_id":"pr-39-pitched-blade-impeller-ptfe","title":"PR 39 Pitched-Blade Impeller (PTFE)","description":"\u003cp\u003ePR 39 propeller stirrer (PTFE) is a laboratory impeller designed for homogenising highly viscous media. Blade geometry suits vessels with an ideal diameter of 188–375 mm, bottom clearance of 38–75 mm, fill height of 188–375 mm and working volumes from 5.200 to 41,400 ml. The stirring element consists of a PTFE blade mounted on a PTFE-coated stainless-steel shaft; the steel core provides rigidity and secure clamping, while the thick-walled PTFE jacket yields an outer shaft diameter of 8 mm. In the chucking zone the diameter is 6,5 mm. Anti-adhesive PTFE surfaces simplify cleaning and permit continuous use up to a maximum application temperature of 250 °C. This propeller stirrer from manufacturer Heidolph is supplied as one piece and is particularly useful where chemical inertness and easy residue release are required. It supports demanding mixing tasks in preparative chemistry, formulation and process laboratories that handle viscous solutions, pastes or suspensions within the stated vessel range.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-fr\/collections\/stirring-shafts-propellers-and-impellers\"\u003eStirring shafts, propellers \u0026amp; impellers\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\u003eProduct type: PR 39\u003c\/li\u003e\n\u003cli\u003eMaterial: PTFE blade with PTFE-coated stainless-steel shaft\u003c\/li\u003e\n\u003cli\u003eShaft diameter (coated): 8 mm\u003c\/li\u003e\n\u003cli\u003eShaft diameter (chuck zone): 6,5 mm\u003c\/li\u003e\n\u003cli\u003eEAN: 4255661402694\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/www.luminixhealth.com\/cdn\/shop\/files\/SANFTE-KRAFTPAKETE_76e5ba49-89b0-4788-afe6-8510ac8a4edb.pdf?v=1790247934\" 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":"Heidolph","offers":[{"title":"Default Title","offer_id":57997729759564,"sku":"5093900010","price":545.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/idl-5093900010.png?v=1783731241","url":"https:\/\/www.luminixhealth.com\/en-fr\/products\/pr-39-pitched-blade-impeller-ptfe","provider":"Luminix Health","version":"1.0","type":"link"}
