Bottle cap to prevent solvent evaporation

Recommend a bottle cap to prevent solvent volatilization. We know that various mobile phases are generated during the working process of liquid chromatography, which may be water phase: formic acid, acetic acid, perchloric acid, etc., or organic phase: methanol , Acetonitrile, methylene chloride, etc. The volatilization of chromatographic mobile phase and waste liquid in the laboratory environment is one of the main sources of laboratory air pollution, which seriously pollutes the laboratory air.

Bottle cap to prevent solvent evaporation


The working principle of the liquid chromatograph is that the mobile phase flows through the injection valve through the infusion pump, is mixed with the sample solution, flows through the chromatographic column, is adsorbed and separated in the chromatographic column, and finally each component is transformed into a telecommunication through a detector. No., the corresponding sample peak appears on the chromatographic workstation.


The SE series of solvent safety bottle caps of Beijing Aowei Instruments effectively filter dust in the air, 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 environment Without being polluted, the product has the following characteristics:


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;


Intubation type waste liquid collection device

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;


The volatilization of mobile phase solvents in the laboratory is an unannounced industry trend. Paying attention to the health of laboratory air will also be the general direction in the future. It is also a green space in the laboratory to protect the health of laboratory personnel.
