The utility model relates to a solution transportation safety lid, including body and filter, the filter includes connecting portion, connects in the filter house and the filtration membrane of connecting portion one end, and sealed joining in marriage of the other end of connecting portion connects in the body, and the filter house has a cavity, and filtration membrane sets up in the cavity, and the filter still includes through connections portion and filter house for the air vent of intercommunication reagent bottle opening and cavity, the one end of air vent intercommunication cavity still is equipped with the control valve, and the control valve is the check valve, opens when being used for compensating the reagent bottle internal gas pressure. So, the in -process of suction reagent, the atmospheric pressure in the guarantee reagent bottle is stable, has improved the smooth and easy nature that the solvent in the reagent bottle was carried. In addition, setting up filtration membrane through the cavity at the filter house, making the air current at first through filtering, the rethread control valve avoids the reagent in the reagent bottle contaminated in getting into the reagent bottle. Still provide a reagent bottle.
