Description
Efficiently manage large-scale reagent additions with our 500ml or 1000ml Pressure Equalizing Graduated Addition Funnel. Crafted from high-quality borosilicate 3.3 glass, this funnel features a chemically resistant PTFE stopcock and a 29/42 taper joint for secure, leak-resistant connections. The pressure-equalizing side arm allows for smooth, consistent dropwise addition without the need for repeated venting, making it ideal for air-sensitive and moisture-sensitive reactions. The clear glass body is graduated with easy-to-read volume markings, so you can monitor liquid addition with precision even at larger volumes.
With a generous 500ml or 1000ml capacity and a 29/42 joint, this addition funnel is an essential tool for organic synthesis, pharmaceutical research, pilot-scale reactions, and any laboratory procedure requiring controlled delivery of larger reagent volumes.
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.
-
29/42 Taper Joint: Ensures a tight, leak-resistant fit with 29/42 compatible flasks, adapters, and stoppers.
-
Premium Borosilicate 3.3 Glass: Excellent thermal shock resistance and chemical durability for long service life.
