500ml Glass Pressure Equalizing Funnel with 24/40 Joint & 4mm Glass Stopcock, Borosilicate Glass Pressure Equalizing Graduated Addition Funnel, Lab Glassware (500 ml)

Pressure equalizing dropping funnels are made of borosilicate glass, durable and of high quality, can withstand typical laboratory thermal variations in chemistry processes.Comparing to an ordinary dropping funnel, the pressure equalizing dropping funnels have an additional narrow-bore glass tube from the upper part of the funnel bulb to the ground glass joint around the stem at bottom.Pressure equalizing addition funnel is commonly used in general closed system experiments and experiments that require dripping solutions.Pressure equalizing funnel is mainly connected with reaction vessel to drop solution, which can isolate the air, prevent solvent from volatilizing, and speed up experiment process.
