Product features

Eggplant flask with long neck and standard ground mouth is a common laboratory glass instrument, usually made of high borosilicate glass. Similar to the short-necked eggplant flask, it has an eggplant-shaped body, a sloped shoulder, and a large bottom volume. This shape is conducive to fully mixing the reactants during the reaction, and is convenient for scraping solid or thick substances in the bottle. At the same time, it can effectively avoid boiling in operations such as vacuum distillation. The neck is long and thin. Compared with the short-necked eggplant flask, the long neck can provide a longer steam path, which is conducive to the cooling and reflux of the steam. In operations such as distillation, the steam can be fully cooled, the distillation efficiency is improved, and the volatilization loss of the substance is reduced.In addition, the long neck is also convenient for connecting other instruments, such as condensers, fractionation columns, etc., making it easy to build complex experimental devices. When conducting some experiments that require precise control of temperature, reactant addition or reaction progress, the long neck can be used as a "buffer area". The bottle mouth has a standard ground mouth interface with a variety of sizes. It can be tightly connected with other glass instruments with the same standard ground mouth to ensure the sealing of the device, making it convenient for experimenters to assemble various experimental devices according to different experimental needs.
