Our rankings are cleverly generated from the algorithmic analysis of thousands of customer reviews about products, brands, merchant’s customer service levels, popularity trends, and more. The rankings reflect our opinion and should be a good starting point for shopping. By purchasing the products we rank, you’ll get the lowest price we found while we may receive a commission at no cost to you, which will help us continue to provide you with value.
Standard Ground Joints: All joints are in the standard 24/40 size, allowing easy replacement of different specifications' glassware. They are sandblasted to ensure airtightness and distillation purity.
Large Capacity Lab Distillation Kit: Our distillation apparatus includes flasks of various capacities to meet diverse distillation needs, enhancing the professionalism and versatility of your experiments. One set satisfies multiple experimental requirements.
3.3 Borosilicate Glass: Upgraded to 3.3 borosilicate glass, our lab glassware withstands high temperatures and corrosive reagents. The low linear expansion coefficient of the glass effectively prevents product breakage due to high temperatures.
Pressure Equalizing Addition Funnel is commonly used in general closed system experiments and experiments that require dripping solutions; it is mainly connected with reaction vessel to drop solution, which can isolate the air, prevent solvent from volatilizing, and speed up experiment process

How do we rank
Our AI-powered platform ranks products using multiple weighted factors from millions of products and user reviews across the web, providing the most valuable and real data. Higher scores rank first.
High Quanlity: Made of high-quality glass, durable and of high quality, can withstand typical laboratory thermal variations in Chemistry processes.
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.
