The evaporation flask is an eggplant or round bottom flask with a standard grind port. In addition, there are always some residues remains at the end of the glassware, which is difficult to clean if heated or left at high temperature for a long time. If the glassware does not get cleaned in time, it will affect the experimental effect. Then how to clean glassware?

How to Choose the Right Cleaning Detergent?

Glass is an amorphous inorganic non-metallic material. It is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash and so on.) As main raw materials, a small amount of auxiliary materials of its main components are silica and other oxides.

The washing detergent is mainly composed of surfactants and builders. When it is applied to the surface of the cleaning object, it combines with the dirt or melts, but it needs running water to wash away its residue. The high-quality washing detergents is made of deionized water and various environmental protection additives. In addition to the above-mentioned properties, some multi-function glass detergents also have the ability to form a bright film on the appearance of the glass, so as to achieve the goal of not leaving traces, water, anti-fog and anti-contamination, and make the glass last forever.
