It suits organic synthesis, extraction setups and general dosing tasks where precise liquid transfer through standard ground joints is required in research, teaching or quality-control laboratories.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/dropping-funnels\"\u003eDropping funnels\u003c\/a\u003e, in \u003ca href=\"\/en-be\/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\u003eType: Cylindrical dropping funnel with pressure equalisation\u003c\/li\u003e\n\u003cli\u003eCapacity: 500 ml\u003c\/li\u003e\n\u003cli\u003eJoint size: NS 29\/32\u003c\/li\u003e\n\u003cli\u003eStopcock: PTFE\u003c\/li\u003e\n\u003cli\u003eEAN: 8434868086470\u003c\/li\u003e\n\u003cli\u003eGTIN: 08434868086470\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-169.pdf?v=1788417308\" 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":57933484032332,"sku":"FTP3500001","price":68.43,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/idl-FTP3500001.png?v=1783731719"},{"product_id":"duran-gls-80-connection-cap-system-wide-mouth-accessories-replacement","title":"DURAN® GLS 80 Connection Cap System, wide mouth (accessories \u0026 replacement parts)","description":"\u003cp\u003eDURAN® pressure equalization set for the 4-Port GL 18 screw closure is a key accessory within the flexible modular GLS 80® connection cap system for transferring liquids or gases. Five tubing diameters (3,2 mm; 6,0 mm; 8,0 mm; 10,0 mm and 12,0 mm) can be connected as required. Sterile pressure equalization is achieved by fitting a syringe membrane filter, while unused ports are sealed with a closed GL 18 PBT cap. Constructed from PP, PTFE and EPDM, the modular design permits individual combination of components to suit specific laboratory needs. Supplied as a single piece from manufacturer Duran\/DWK Life Sciences, the set is fully compatible with all GLS 80 threads and therefore highly versatile across vessel types. Typical applications include liquid transfer, continuous feed of media into bioreactors, controlled addition of reagents to analytical instruments and operation of photobioreactors.

With a nominal capacity of 250 ml and a net weight of 0,257 kg, the unit suits preparative chemistry and dosing tasks where both chemical resistance and visibility of the contents are required. Supplied as one piece from manufacturer Bohlender, this dropping funnel connects to standard ground-joint apparatus used in synthetic and analytical laboratories. The combination of an FEP body and PTFE stopcock components addresses aggressive media that challenge conventional materials, making it a practical choice for precise addition of corrosive or reactive liquids in routine laboratory workflows.\u003c\/p\u003e\n\u003c!-- lx-pdp-inline --\u003e\n\u003cp\u003eThis article is part of \u003ca href=\"\/en-be\/collections\/dropping-funnels\"\u003eDropping funnels\u003c\/a\u003e, in \u003ca href=\"\/en-be\/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\u003eMaterial: FEP body, PTFE stopcock\u003c\/li\u003e\n\u003cli\u003eCapacity: 250 ml\u003c\/li\u003e\n\u003cli\u003eGround joint: NS 29\/32\u003c\/li\u003e\n\u003cli\u003eDesign: SAFE LAB\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Bohlender","offers":[{"title":"Default Title","offer_id":57935982330188,"sku":"B28502","price":661.22,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0955\/4827\/7068\/files\/NY53-1000Wx1000H_dd55f486-f006-415b-8d9f-968a359a97c1.jpg?v=1791409176"}],"url":"https:\/\/www.luminixhealth.com\/en-be\/collections\/dropping-funnels.oembed?page=7","provider":"Luminix Health","version":"1.0","type":"link"}
