APOLLO Constant Pressure Feeding Funnel with Dual PTFE Stopcocks – 2000 mL
Designed for precise, controlled reagent addition under atmospheric, inert gas, or reduced-pressure conditions, the APOLLO 2000 mL Constant Pressure Feeding Funnel with Dual PTFE Stopcocks is manufactured from premium laboratory-grade borosilicate glass, providing exceptional chemical resistance, thermal durability, and outstanding optical clarity. Its integrated pressure-equalizing tube maintains constant internal pressure between the funnel and reaction vessel, ensuring smooth, uninterrupted reagent delivery while preserving the reaction atmosphere.
Featuring 24/40 standard ground glass joints, the funnel is equipped with dual chemical-resistant PTFE stopcocks—one controlling reagent flow into the reaction vessel and the second regulating pressure equalization and venting. This dual-valve configuration provides enhanced control over liquid addition, making it ideal for air-sensitive, moisture-sensitive, and highly controlled reaction processes.
Engineered for professional laboratory applications, the APOLLO Constant Pressure Feeding Funnel with Dual PTFE Stopcocks is perfectly suited for chemical synthesis, reflux, distillation, polymerization, pharmaceutical manufacturing, biotechnology, and research laboratories.
