Design: The Laboy Pressure-equalizing Dropping Funnel is a specially designed laboratory glassware that has 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 has a standard taper glass outer joint at the top and inner joint at the bottom, with two PTFE stopcocks.
Usage: The funnel is used for precise addition of reagents and solutions in liquid handling experiments, especially in chemical synthesis and analytical applications.
Material: The Laboy Pressure-equalizing Dropping Funnel is made of high-quality borosilicate glass, which makes it highly resistant to thermal shock, chemical corrosion, and mechanical impact.
Craft: The Laboy Pressure-equalizing Dropping Funnel is heavy wall designed and made by hand-blowing to ensure uniform wall thickness. It is annealed at 800 degrees Celsius to increase its durability and longevity. The two PTFE stopcocks ensure smooth and accurate control of the liquid flow during the experiment.
