Designed for controlled reagent addition in closed reaction systems, with a pressure-equalizing arm that maintains balanced pressure for smooth, controlled dispensing while helping minimize solvent evaporation.
Features a PTFE metering stopcock with an adjustable-bore plug for precise flow control from dropwise dispensing to full flow, helping prevent sudden overflow or interrupted flow during reagent addition.
Features same-size top outer and lower inner standard taper joints, with a drip tip on the lower joint.
Funnels with capacities from 10 to 250 mL are equipped with a 2 mm bore stopcock, while funnels with capacities of 500 mL or greater are equipped with a 4 mm bore stopcock.
