No. 7

ADAMAS-BETA Glass Equalizing Dropping Funnel,Constant Pressure Funnel with PTFE Stopcock Chemistry Laboratory Glassware (250ml,24/40 Joint)

Design: 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. The pressures in the reservoir and the reaction flask are equal, and liquid will flow into the reaction flask even when the stopper is in place in the funnel. Pressure-equalizing dropping funnels are normally only used for inert atmosphere reactions.
Advantage: When adding liquid to an ordinary separatory funnel, it is necessary to open the stopper on the upper end of the funnel or align the groove on the stopper with the small hole on the bottle mouth, so that the liquid in the funnel can flow down smoothly. While the constant pressure dropping funnel has an upper connected tube, which can balance the air pressure without opening the stopper.
High Quanlity: Made of high-quality glass, durable and of high quality, can withstand typical laboratory thermal variations in Chemistry processes.
Multiple sizes: Capacity 10ml,25ml,60ml,125ml,250ml,500ml,1000ml; joints 14/20,19/22,24/40,14/22. Various specifications are availiable for your choice.
Warranty: Glassware is fragile, if received damaged, please don't hesitate to contact us, we will solve it until satisfied.
