Produced from high-quality borosilicate glass LBG 3.3 in accordance with DIN \/ ISO 4800 and 3585, the funnel features clear graduation that allows direct volume observation during dosing. Its cylindrical form integrates easily into standard clamp and stand arrangements, while the PTFE plug provides chemically resistant, smooth stopcock control and the plastic stopper closes the upper neck securely. This 250 ml model from manufacturer Labbox is part of the GLASSCO range and has a net weight of 0,440 kg, offering a compact yet practical capacity for medium-scale reactions, extractions and reagent addition. Graduated scale markings help maintain dosing accuracy without additional measuring glassware. The robust borosilicate body combined with PTFE sealing components supports reliable everyday use in research, quality-control and teaching environments where dropwise or continuous addition of reagents is essential.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/nl-nl\/collections\/dropping-funnels\"\u003eDropping funnels\u003c\/a\u003e, in \u003ca href=\"\/nl-nl\/collections\/funnels\"\u003eFunnels\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\u003eCapacity: 250 ml\u003c\/li\u003e\n\u003cli\u003eMaterial: Borosilicate glass LBG 3.3\u003c\/li\u003e\n\u003cli\u003eConfiguration: PTFE plug and plastic stopper\u003c\/li\u003e\n\u003cli\u003eShape: Cylindrical with graduation\u003c\/li\u003e\n\u003cli\u003eEAN: 8434868088542\u003c\/li\u003e\n\u003cli\u003eGTIN: 08434868088542\u003c\/li\u003e\n\u003cli class=\"lx-tis-li\"\u003eTechnical Information Sheet: \u003ca class=\"sds-link\" href=\"https:\/\/www.luminixhealth.com\/cdn\/shop\/files\/pds-1530.pdf?v=1788413930\" 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":"Labbox","offers":[{"title":"Default Title","offer_id":57933561037132,"sku":"SFCG250001","price":42.25,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/idl-SFCG250001.png?v=1783731251","url":"https:\/\/www.luminixhealth.com\/nl-nl\/products\/dropping-funnel-with-ptfe-stopcock-and-plastic-stopper-cylindrical-250-ml","provider":"Luminix Health","version":"1.0","type":"link"}
