Title
Design: The Laboy Pressure-equalizing dropping funnel has a unique design with 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 features a standard taper glass outer joint at the top and an inner joint at the bottom, with a glass stopcock on the upper part of the bottom glass joint.
Usage: The Pressure-equalizing dropping funnel is commonly used in chemistry laboratories for adding reagents in small amounts to reactions under an inert atmosphere or for the addition of air-sensitive reagents. The added narrow-bore glass tube allows for pressure equalization between the inside of the funnel and the reaction flask, providing more controlled and precise additions.
Material: Laboy glassware is made of high-quality borosilicate glass, which is known for its superior thermal and chemical resistance, high clarity, and durability.
Craft: Laboy glass flasks are heavy wall designed, ensuring uniform wall thickness and preventing uneven heating and cooling. Each piece is made by hand-blowing, which ensures accuracy and precision.
Guarantee: Laboy offers a 100% 40-day money-back guarantee. If not satisfied, the product can be returned for a full refund, no questions asked.
