SV series solvent safety caps can be used for the safe sealing of solvent bottles in liquid chromatography, automatic solid-phase extraction, pressurized solvent extraction instruments and other equipment. When the equipment is working, it can efficiently filter dust in the air to prevent solvent pollution and ensure the accuracy of analysis results as well as can preventing the solvent from volatilizing when the instrument stops working in order to protect the laboratory environment from pollution.

Unilateral Seal -Prevent Evaporation

With high sensitivity one-way inlet valve, when the instrument stops working, the inlet valve automatically seals to prevent the solvent from evaporating which can maximum protect laboratory safety;

External microporous filter-saving cost                       

The normal safety cap needs to replace valves every 6 months, high cost in maintenance. Auwii SV series products innovatively adopt a split design, and externally install the microporous membrane that is easy to be clogged by dust. The using cost is greatly reduced due to a low replacement cost. 

Time Label -Expiration Reminder 

 The time label on SC solvent safety caps record the use time in the form of a red progress bar to remind the user to replace the micro-porous filter when it is due.
