Comparison of the cleaning method of Cover Glass

Glass sheet is a thin glass piece sealed on the slice of the glass slice. It is often used in tissue teaching and scientific research. It is also a commonly used equipment for pathology and inspection. Essence

At present, the Gats sheets sold in the sales are free -range and ordinary. Most of the Glass pieces sold abroad are exempt. They have been specially treated during production and can be used directly. Domestic products are not specially treated. The dirt and alkaline substances are susceptible to moisture during the storage process to breed mold on the surface. Under the microscope, it is cloudy -like, which seriously affects the clarity of tissue observation. Therefore, the caps need to be cleaned before use.

Ethanol can dissolve organic dirt, but it is not ideal to remove mold, the effect is general and time -consuming. Disposal solution is low toxic, saving time and effort, but the cleaning effect is average, and it is easy to leave water marks. Both cleaning liquids are suitable for the treatment of mild pollution and mildew. The potassium chromium -sulfate is cleaned thoroughly, and it can completely remove organic, inorganic dirt and mildew, but the process is complicated, it is difficult to rinse it, it is easy to pollute the environment, and it is easy to corrode clothing and skin. Ethanol -hydrochloride washing solution can remove mold spots, has a bactericidal effect, simple operation, low cost, corrosive, small environmental pollution, high efficiency and low loss. The phenol water solution is strong, the cleaning effect is very good, and the operation is simple. Sterilizer and disinfection of peroxybonitate solution is strong, cheap, clean and thorough, but corroded the skin. Rare sulfuric acid operation is simple, fast, and strong pollution. Sodium hydroxide solution is simple, but long bubbles will corrode glass. The cleaning effect of oxalic acid water solution is good, and the long -bubbles are not damaged, but the operation costs time. The cleaning effect of 5 % sulfuric acid solution and 5 % ammonia aquatic solution is good, but the operation is cumbersome: the cleaning effect of the people's mermaid solution is very good, and the effect is rapid. The cleaning effect of ammonia hydroxide and hydroxide hydroxide solution is better and fast.

Because the surface dirt on the covering piece is mainly derived from the residual organic matter, alkaline substances and the moldy changes in storage in production, the commonly used cleaning liquid is mainly acidic chemical cleaning solution, which combines dissolving organic matter and alkaline substances, and removed. The effect of mold is better. The general cleaning ceiling glass can be cleaned with ethanol or detergent. When the medium -weight pollution and mildew are severe, the acid potassium acid washing solution is needed.
