Product features

Pear shape distilling flask with two necks and standard ground mouth is a laboratory glass instrument used for fractionation operations, usually made of high borosilicate glass. The overall shape is pear-shaped, which allows the liquid in the flask to form a larger heating area when heated, which is conducive to the evaporation and fractionation of the liquid. At the same time, the pear-shaped design makes it easy to concentrate the different fractions after distillation at the bottom of the bottle, reduce liquid residue, and facilitate the collection and transfer of products. The bottle mouth has a standard ground joint and comes in a variety of sizes,it can be tightly connected with other glass instruments with the same standard ground mouth, such as fractionation columns, condensers, receiving flasks, etc., to ensure the sealing of the device, and facilitate experimenters to assemble various fractionation devices according to different experimental needs. There is a branch pipe at the bottleneck for connecting the fractionation column or condenser. During fractionation, the generated steam enters the fractionation column through the branch pipe, and is vaporized and condensed multiple times in the fractionation column, thereby achieving the separation of components with different boiling points.

Pear shape distilling flask has stable technology, fine workmanship, standard ground mouth, fine frosting, tight seal, and national standard taper of 1:10. High borosilicate material, high expansion coefficient, high temperature resistance. Smooth and translucent, smooth surface, easy to observe.
