SE series solvent safety bottle caps can be used for the safe sealing of solvent bottles in instruments and equipment such as liquid chromatography, automatic solid phase extraction, and pressurized solvent extraction. When the instruments and equipment are working, they can efficiently filter dust in the air to prevent solvent contamination and ensure The analysis result is accurate. When the instrument stops working, it can prevent the solvent from volatilizing through the air inlet, and protect the laboratory environment from pollution.

Microporous Membrane—— Efficient Filtration
○  SE series solvent safety cap built-in PTFE microporous membrane which can efficiently filter the air so that prevent dust from contaminating the solvent and ensure the accuracy of the analysis results;

Non-Return Seal—— Prevent Volatilization
○  SE series solvent safety cap adopt high-sensitivity non-return safety valve. Once chromatographic instrument stops working, the safety valve will close and seal so that the mobile phase is prevented from volatilizing through the air inlet to protect the laboratory environment and take care of experimenter.

Time Label —— Expire Reminder
○  Press time start button on the valve once start use, the time label will record the use time in the form of a red progress bar, remind the user replace the safety valve on schedule;

Plug Installation—— Easy to Replacement
○  The safety valve on the SE series solvent safety cap is recommended to be replaced every 6 months. It adopts a quick plug installation design, which can be replaced easily by users;
