Receiving Flask with Joint & Bottom PTFE Vacuum Valve, 500-5000ml

This high-vacuum receiving flask with a precision ground joint is engineered for convenient liquid collection and controlled discharge in vacuum distillation and analytical workflows. Constructed from chemical-resistant borosilicate glass, the vessel features an integrated bottom high-vacuum valve equipped with a PTFE core to ensure exceptional corrosion resistance, superior sealing integrity, and effortless draining without disrupting system operations.

Key Features:

• Premium Borosilicate Glass: Fabricated entirely from high-grade borosilicate glass to deliver outstanding chemical durability and superior thermal resistance under continuous vacuum operation.
• Corrosion-Resistant PTFE Valve Core: Features a high-purity PTFE valve inner core that provides excellent chemical inertness against harsh acids, solvents, and corrosive reagents.
• Convenient Bottom Discharge Design: Equipped with a bottom-mounted high-vacuum valve that enables smooth, controlled draining of collected fluids without disrupting internal pressure or dismantling the system.
• High-Vacuum Sealing Integrity: Engineered to maintain an airtight seal during high-vacuum operations, preventing contamination and leakage during sensitive distillation processes.
• Standard Ground Glass Joint: Features a precision-ground glass joint at the top for seamless, leak-proof integration with standard laboratory glass assemblies and receiving adapters.
• Scalable Capacity Range: Available in standard laboratory volumes ranging from 500ml to 5000ml to accommodate both benchtop synthesis and pilot-scale collection needs.
