Chemistry students, home lab enthusiasts, and professionals, this DONLAB separatory funnel is built for precise liquid separation work. The 500ml capacity is perfect for most laboratory applications, whether you're performing extractions, separations, or washing procedures. The borosilicate glass (boro3.3) construction is what makes this funnel reliable - it's resistant to thermal shock and chemical corrosion, so you can use it with various solvents and solutions without worrying about degradation. The PTFE stopcock is a crucial feature - it provides excellent chemical resistance and smooth operation without seizing or leaking, which is a common problem with glass-on-glass stopcocks. The #24/29 standard ground glass opening ensures compatibility with other lab glassware, and the plastic stopper provides a secure seal at the top. I've used this for organic chemistry extractions and it performs flawlessly - the conical shape allows for clean separation of immiscible liquids, and the stopcock controls flow precisely. Whether you're setting up a home laboratory, teaching chemistry concepts, or need reliable equipment for professional work, this separatory funnel delivers the quality and precision that serious chemistry work demands.
