Mobile phase reservoir

摘要

The present invention relates to a reservoir for storage and use of the liquid or mobile phase of a liquid chromatography system. The reservoir comprises a main chamber for containing the majority of the mobile phase and having a conical base with two apertures and two cavities subtending the apertures and in fluid communication with the main chamber. These cavities are adapted to receive a stirrer and a pump filter and to maintain these devices separate from each other during operation. The structure of the reservoir provides for more rapid and thorough mixing and virtually complete utilization of the mobile phase while minimizing introduction of gaseous phase into the liquid chromatography system downstream from the reservoir.
