Design: The Pressure-equalizing dropping funnel is designed 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 also features a standard taper glass outer joint at the top and inner joint at the bottom, with a high vacuum valve.
Usage: The Pressure-equalizing dropping funnel is commonly used in chemistry processes that require precise control of the addition of reagents, especially in air-sensitive reactions or reactions that generate gases. The high vacuum valve allows for accurate control of the pressure within the funnel and ensures a controlled, steady flow of reagents.
Material: The Pressure-equalizing dropping funnel is made of high-quality borosilicate glass, which is annealed at 800 degrees Celsius to ensure uniform wall thickness and maximum durability. The glass can be heated directly in an open flame and is resistant to typical laboratory thermal variations.
Craft: The Pressure-equalizing dropping funnel is heavy wall designed and made by hand-blowing to ensure precision and quality. The funnel features a high vacuum valve that is carefully crafted to ensure accurate control of the pressure within the funnel.
Guarantee: Laboy offers a 100% 40-day money-back guarantee for the Pressure-equalizing dropping funnel. If the customer is not satisfied with the product, they can return it for a full refund, no questions asked.
