Product features

Eggplant shape flasks are generally glass instruments used for heating chemical substances. The materials used are relatively strict. They use high borosilicate glass, which is thin, uniform, and resistant to sudden cooling and heating. Its thermal expansion coefficient is extremely low, only one-third of ordinary glass. This material is not only resistant to high temperatures, but also can withstand drastic temperature changes of 200 degrees, ensures stability during the experiment. It has high hardness, high transparency and corrosion resistance.The lower part is round-bottomed and the upper part gradually narrows. This special shape not only helps stir the solution and reduce the generation of bubbles during the reaction, but also increases the exposed area of the liquid surface, thereby accelerating the reaction process. In addition, eggplant shape flasks are often used in conjunction with rotary evaporators and are widely used in experimental operations such as drug extraction, solvent extraction, and soaking. The unique design of the eggplant shaped flask enables it to be heated evenly during the heating process, reduces the risk of local overheating. It ranges from 10ml to 3000ml to meet different experimental needs and is extremely flexible.

The sloping side wall design of the eggplant shape flask makes it easy to scrape off and pour out the solids precipitated during the rotary evaporation process, which facilitates subsequent separation and purification operations. Due to its unique shape, the eggplant shape flask is ideal for evaporating large amounts of liquid in a rotary evaporator to improve experimental efficiency. During the process of concentrating liquid, the pointed bottom design of the eggplant shape flask allows the small amount of liquid product left to flow naturally to the bottom of the bottle, makes it easy to suck it out with tools such as straws. Its shape and material make the cleaning process relatively simple and less likely to retain dirt.

Compared with flasks of other shapes, the eggplant shape flask has better pressure resistance due to its large bottom contact area and uniform force, and can withstand higher pressure without being prone to rupture. Eggplant shape flasks are often used for vacuum distillation in chemical experiments. The bottom volume of the bottle is larger, which can avoid bumping caused by too much liquid during the distillation process.

Product applications

In daily experiments, eggplant shape flasks are often used in the operation of rotary evaporators (rotary evaporators). By rotary evaporation, solutions can be concentrated efficiently, saves time and effort. In addition, it is suitable for a variety of chemical reactions, especially where precise control of temperature and pressure is required.

Eggplant shape flasks are generally used for microbial seed preparation in laboratories and production processes. Eggplant shape bottles can also be used in biological products factories, as culture equipment for breeding vaccines, or in scientific research units such as medical and health care, medical schools, etc., to conduct culture analysis and research on isolated living tissue cells or dispersed living cells and viruses, and observe various changes in their growth processes. It is suitable for testing thick substances or as a receiving bottle. The thick substance can be scraped directly with a scraper because of its slope-shaped shoulder.
