{"product_id":"rotilabo-stoppers-w-hole-nat-rubber-y851-y851","title":"Rotilabo®-stoppers w. hole, nat. rubber, Ø borehole 5 mm, Ø bottom 21 mm","description":"\u003cp\u003eRotilabo® stoppers with hole, natural rubber, provide a practical seal for laboratory vessels while allowing passage of tubing or probes through a central borehole. This larger variant specifies a borehole diameter of 5 mm and a bottom diameter of 21 mm, addressing wider necks on flasks, bottles and comparable labware. Natural rubber supplies the elasticity required for secure seating and repeated insertion under normal laboratory conditions. Packaged as 10 pc(s) with a total weight of 0,170 kg, the unit is suitable for focused workstations or smaller inventory needs. These Rotilabo® stoppers from manufacturer ROTH SELECTION fit routine sealing tasks in chemical, biological and general analytical settings where both closure and through-access matter. The tapered profile supports a firm fit against the vessel opening, and the defined hole maintains a clear channel for connections. They belong to standard laboratory plugs and stopper consumables chosen for consistent dimensions and straightforward natural-rubber performance in daily experimental workflows.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/fr-fr\/collections\/rubber-and-silicone-stoppers\"\u003eRubber \u0026amp; silicone stoppers\u003c\/a\u003e, in \u003ca href=\"\/fr-fr\/collections\/stoppers-caps-and-closures\"\u003eStoppers, caps \u0026amp; closures\u003c\/a\u003e.\u003c\/p\u003e\n\n\u003ch3\u003eKey features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePack size: 10 pc(s)\u003c\/li\u003e\n\u003cli\u003eBrand: Rotilabo®\u003c\/li\u003e\n\u003cli\u003eMaterial: Natural rubber\u003c\/li\u003e\n\u003cli\u003eDesign: Stoppers with hole\u003c\/li\u003e\n\u003cli\u003eBorehole diameter: 5 mm\u003c\/li\u003e\n\u003cli\u003eBottom diameter: 21 mm\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Carl Roth","offers":[{"title":"10 pc(s) \/ 1 piece","offer_id":56186844873036,"sku":"Y851.1","price":11.05,"currency_code":"EUR","in_stock":true},{"title":"10 pc(s) \/ 6+ pieces","offer_id":56186844905804,"sku":"Y851.1","price":10.5,"currency_code":"EUR","in_stock":true},{"title":"10 pc(s) \/ 24+ pieces","offer_id":56186844938572,"sku":"Y851.1","price":9.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/Y855-1000Wx1000H_94f6f485-2cba-4750-b106-bd26c624e467.jpg?v=1766501616","url":"https:\/\/www.luminixhealth.com\/fr-fr\/products\/rotilabo-stoppers-w-hole-nat-rubber-y851-y851","provider":"Luminix Health","version":"1.0","type":"link"}
