Laboy Glass Pressure-Equalizing Dropping Funnel with PTFE Stopcock and Standard Taper Joints

Design: The Laboy Pressure-equalizing Dropping Funnel features an additional narrow-bore glass tube from the upper part of the funnel bulb to the ground glass joint around the stem at the bottom. It also has a standard taper glass outer joint at the top and an inner joint at the bottom, with a PTFE stopcock on the upper bottom glass joint. Usage: This type of dropping funnel is ideal for use in chemistry processes where pressure needs to be equalized, such as in gas washing and liquid-liquid extractions. The narrow-bore glass tube helps to ensure that pressure is equalized between the two phases, making it easier to control the rate of flow during the experiment. Material: The funnel is made of high-quality borosilicate glass, which is heavy-wall designed and hand-blown to ensure uniform wall thickness. It is also annealed at 800 degrees Celsius, making it durable and able to withstand typical laboratory thermal variations, including heating and cooling. Craft: The funnel is careful
