Abstract

The utility model discloses a mobile phase bottle for a liquid chromatograph, a forming die thereof and a mobile phase loading structure. The mobile phase bottle is placed above the liquid chromatograph, at the moment, the liquid level of the mobile phase has a certain height difference to the inlet of the liquid phase pump, so that natural flowing power is formed, and the liquid phase pump is more favorable for absorbing liquid smoothly. The mobile phase bottle comprises a bottle body and a mobile phase containing cavity arranged in the bottle body. The bottom of the mobile phase containing cavity is of an inverted cone structure. The structure of the mobile phase bottle is optimized, so that the mobile phase at the bottom of the bottle is converged on the conical part, thereby achieving the effect of fully sucking the mobile phase in the bottle, and solving the problems that when the traditional liquid chromatograph works, the liquid level in the bottle cannot pass through a liquid suction port and the mobile phase cannot be sucked out, gas enters a pipeline and the work of the liquid chromatograph is influenced when the mobile phase is about 1/10 of the rest.
