Description
Achieve flawless reagent addition in any reaction scale with our Pressure Equalizing Graduated Addition Funnel. Engineered for precision and durability, this funnel is crafted from high-quality borosilicate 3.3 glass and features a chemically inert PTFE stopcock plus a 24/40 standard taper joint for secure, leak-resistant connections. The pressure-equalizing side arm ensures smooth, consistent dropwise addition without the need for repeated venting, making it indispensable for air-sensitive and moisture-sensitive reactions. The clear glass body is graduated with easy-to-read volume markings, allowing you to monitor liquid addition with accuracy from start to finish.
Available in five versatile capacities—60ml, 125ml, 250ml, 500ml, and 1000ml—this addition funnel is the ideal choice for organic synthesis, pharmaceutical research, pilot-scale reactions, and any laboratory procedure requiring controlled delivery of reagents.
Key Features & Benefits:
-
Pressure Equalizing Design: The integral side arm equalizes pressure between the funnel and the reaction vessel, ensuring steady dropwise addition and preventing backpressure or vacuum issues.
-
PTFE Stopcock: Chemically inert and highly resistant to aggressive solvents, acids, and bases. Provides smooth, precise flow control without seizing or contamination.
-
Graduated Body: Clear volume markings on the borosilicate glass allow for accurate monitoring of liquid dispensed and remaining.
-
24/40 Standard Taper Joint: Ensures a tight, leak-resistant fit with 24/40 compatible flasks, adapters, and stoppers.
-
Premium Borosilicate 3.3 Glass: Excellent thermal shock resistance and chemical durability for long service life.
-
Multiple Capacity Options: Choose from 60ml, 125ml, 250ml, 500ml, or 1000ml to suit your specific reaction scale—from small-scale synthesis to pilot-scale processes.
