Liquid-phase solvent bottle cap is a kind of safety bottle cap product specially used to seal and filter the volatilization of liquid phase. It belongs to a kind of consumables often used in laboratories. 

Solvents are those that can dissolve solid, liquid or gaseous solutes. The liquid then becomes a solution. Solvents are usually transparent, colorless liquids, and most of them have unique odors, low boiling points and easy volatilization. Or it can be removed by distillation, leaving the dissolved material behind. The most common example is brewing coffee or tea with hot water. The most common solvent in daily life is water. The so-called organic solvent is an organic compound solvent containing carbon atoms.

This kind of liquid phase solvent is generally produced in liquid chromatography. In liquid chromatography, calcium carbonate is placed in a glass tube, and petroleum ether containing plant pigments (plant leaf extract) is poured into the tube. At this time, a mixed band of several colors appeared at the upper end of the glass tube. Then rinse with pure petroleum ether. With the addition of petroleum ether, the band moves downward and gradually separates into several bands of different colors. By continuing to rinse, you can receive various colors of pigments, and they can be separated. Perform identification.

The volatilization of the chromatographic mobile phase and the volatilization of waste liquids in the laboratory environment are one of the main sources of laboratory air pollution, which seriously pollutes the laboratory air. If you do not pay attention to filtering and sealing factors when collecting liquid solvents, it will last forever. The result will be pollution of the laboratory environment and damage to the health of laboratory staff, and the liquid solvent bottle cap is a product specifically designed to solve this problem.

For example, Beijing Aowei Instrument SE series solvent safety bottle caps efficiently filter dust in the air to prevent mobile phase contamination and ensure the accuracy of analysis results; when the chromatographic instrument stops working, it prevents the mobile phase from volatilizing through the air inlet to protect the laboratory The environment is not polluted, and its characteristics are as follows:

microporous membrane-high efficiency filtration

SE series solvent safety bottle caps have a built-in PTFE microporous filter membrane to efficiently filter the air entering the mobile phase bottle to prevent dust from polluting the solvent and ensure the accuracy of the analysis results;

One-way seal-prevent volatilization

SE series solvent safety bottle caps use a high-sensitivity one-way safety valve. When the chromatographic instrument stops working, the safety valve is closed and sealed to prevent the solvent in the bottle from volatilizing outward, protect the laboratory environment and the health of the experimenters;

Time tag-due reminder

When the SE series solvent safety bottle cap is used, press the time start button on the safety valve, and the time label will record the time of use in the form of a red progress bar, reminding users to replace the safety valve on schedule;

plug-in installation-easy to replace

The safety valve on the SE series solvent safety bottle cap is recommended to be replaced after 6 months of use. The safety valve adopts a quick plug-in installation design, which can be replaced by the user;

At the time when green and environmental protection are promoted everywhere, the environment and personnel health in the laboratory also need to be paid attention to. If your laboratory also has a problem of liquid solvent collection, we suggest you to take a look at our liquid solvent bottle cap product. The quality of the branded products is guaranteed, and the cost performance is very high. After the product was launched, it has won the favor of the majority of laboratory users.
