Longitudinal ribs along the inner cone wall create air channels between the funnel and the liquid surface, preventing the suction seal that blocks flow and causes splashing when using smooth-wall funnels. The 60 mm opening accommodates standard flask and bottle neck sizes and provides ample cross-sectional area for liquids, powders, and granular solids.\u003c\/p\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eValue\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number (MPN)\u003c\/td\u003e\n\u003ctd\u003e208-5136-030\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOpening Diameter\u003c\/td\u003e\n\u003ctd\u003e60 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eFunnel Style\u003c\/td\u003e\n\u003ctd\u003eRibbed Funnel, Conical Body\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMaterial\u003c\/td\u003e\n\u003ctd\u003ePolypropylene (PP)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eColor\u003c\/td\u003e\n\u003ctd\u003eNatural\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSterility\u003c\/td\u003e\n\u003ctd\u003eNon-Sterile\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePack Size\u003c\/td\u003e\n\u003ctd\u003e100\/Bag\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBPA \/ Phthalate \/ Latex\u003c\/td\u003e\n\u003ctd\u003eBPA-Free, Phthalate-Free, Latex-Free\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCountry of Origin\u003c\/td\u003e\n\u003ctd\u003eUSA\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eApplications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eLiquid transfer into 50–500 mL Erlenmeyer flasks and round-bottom flasks — ribs eliminate suction lock for smooth, controlled flow\u003c\/li\u003e\n\u003cli\u003eReagent bottle filling for narrow-neck bottles from 125 to 1000 mL, where the 60 mm opening fits standard neck diameters\u003c\/li\u003e\n\u003cli\u003eSPE eluate collection and transfer using acetonitrile or methanol mobile phases — PP's solvent resistance makes these funnels the right choice over polystyrene alternatives\u003c\/li\u003e\n\u003cli\u003ePowder and granular solid transfer into volumetric flasks and weighing bottles, where the ribbed wall reduces bridging of fine particles\u003c\/li\u003e\n\u003cli\u003eGravity filtration setups accepting standard 9–11 cm filter paper over conical collection flasks\u003c\/li\u003e\n\u003cli\u003eColumn packing for SPE and chromatography columns, providing controlled solvent and sorbent addition\u003c\/li\u003e\n\u003cli\u003eMulti-analyte and GMP workflows where single-use format eliminates the cost and compliance burden of funnel cleaning and re-validation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eChemical Resistance\u003c\/h2\u003e\n\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eReagent \/ Transfer Medium\u003c\/th\u003e\n\u003cth\u003eCompatibility\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eAqueous buffers, saline, and water\u003c\/td\u003e\n\u003ctd\u003eExcellent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDilute acids and bases\u003c\/td\u003e\n\u003ctd\u003eExcellent\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMethanol and acetonitrile\u003c\/td\u003e\n\u003ctd\u003eGood — suitable for SPE eluate transfer\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eEthanol (\u0026lt;70%)\u003c\/td\u003e\n\u003ctd\u003eGood — short-term contact\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eConcentrated acids and bases\u003c\/td\u003e\n\u003ctd\u003eGood — short-term contact; verify concentration\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eChlorinated solvents (chloroform, DCM)\u003c\/td\u003e\n\u003ctd\u003eNot recommended\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAromatic solvents (toluene, xylene)\u003c\/td\u003e\n\u003ctd\u003eNot recommended\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch2\u003eQuality \u0026amp; Procurement\u003c\/h2\u003e\n\u003cp\u003eMade in USA, these Caplugs® Evergreen funnels are produced from FDA-compliant, food-contact-grade polypropylene resin under ISO 9001 quality management, and are certified BPA-free, phthalate-free, and latex-free.
