The safety cap for the liquid solvent bottle of Beijing Aowei Instrument is a green product specially used to purify the laboratory air and protect the health of laboratory personnel. It is one of the products in the “Green Laboratory Solution” of Aowei Instrument. , Including liquid chromatography solvent safety bottle cap, intubation type waste collection device, funnel type waste collection device 3 categories.

First of all, everyone knows that 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, and the liquid solvent is In the device of the waste liquid collection system, when the liquid chromatograph organic solvent is used as the mobile phase, the following more difficult problems are often encountered.

1: Organic solvents are volatile liquids. They will evaporate in large quantities from the space in the bottle caps into the indoor air, resulting in a great smell of indoor solvents, causing environmental pollution and serious damage to the health of the staff.

2: If the bottle mouth is sealed and air circulation is blocked, a closed negative pressure vacuum environment will be formed in the solvent bottle during solvent injection, and the solvent cannot be extracted. In the waste liquid collection, the solvent bottle will form In a positive pressure and high pressure environment, waste liquid cannot be injected into the container.

3: Punch a vent or open interface on the mobile phase bottle cap. When the solvent is extracted, dust and other impurities in the air will enter the mobile phase bottle together with the air, causing solvent pollution.

At this time, the SE series solvent safety bottle caps of Beijing Aowei Instruments efficiently 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 experiment It is particularly important that the room environment is not polluted. Not only that, this wide product also has the following high-quality features:

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;

Beijing Aowei Instrument Liquid Solvent Bottle Safety Bottle Cap is a green product that can really help you purify the air in the laboratory and protect the health of the experimenters. Under the current trend of advocating green and environmental protection, you may be in need of such a product Help you enter the laboratory 3.0 era.
