What's in This Collection?
- Stonylab 3,000ml Conical Separatory Funnel – Borosilicate Glass & PTFE Stopcock — a large-capacity, professional-grade separatory funnel engineered for demanding laboratory applications. 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.
Why These Are the Best Laboratory Funnel Buys
- Borosilicate glass (Type 3.3) — the gold standard in laboratory glassware, offering superior chemical and thermal resistance compared to standard glass
- PTFE stopcock — chemically inert, grease-free, and leak-proof — far more reliable than traditional glass stopcocks that require greasing and can seize
- 3,000ml large capacity — handles substantial sample volumes for preparative and industrial-scale separation work
- Conical design — the tapered conical shape allows clear phase separation and precise layer identification during extraction
- Stonylab quality assurance — a trusted laboratory glassware brand with consistent manufacturing standards and strong user reviews
