Crafted from high-quality borosilicate glass (Type 3.3), it offers exceptional resistance to thermal shock, acids, alkalis, and organic solvents — making it suitable for the full range of liquid-liquid extraction protocols. The PTFE (polytetrafluoroethylene) stopcock provides a chemically inert, leak-free seal that outperforms traditional glass stopcocks in both reliability and ease of use. At 3,000ml capacity, it handles large-volume separations with ease, making it ideal for preparative chemistry, solvent extraction, and industrial-scale research applications. Available in two variants to suit different laboratory setups and workflow requirements.\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eWhy These Are the Best Laboratory Funnel Buys\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBorosilicate glass (Type 3.3)\u003c\/strong\u003e — the gold standard in laboratory glassware, offering superior chemical and thermal resistance compared to standard glass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePTFE stopcock\u003c\/strong\u003e — chemically inert, grease-free, and leak-proof — far more reliable than traditional glass stopcocks that require greasing and can seize\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e3,000ml large capacity\u003c\/strong\u003e — handles substantial sample volumes for preparative and industrial-scale separation work\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConical design\u003c\/strong\u003e — the tapered conical shape allows clear phase separation and precise layer identification during extraction\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStonylab quality assurance\u003c\/strong\u003e — a trusted laboratory glassware brand with consistent manufacturing standards and strong user reviews\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutstanding value\u003c\/strong\u003e — professional-grade separatory funnels at prices that suit both academic and commercial laboratories\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eEquip your lab with glassware that performs as precisely as your science demands.
