Reagent vessel cap and method for collecting reagent

摘要

A reagent vessel cap (2) includes a sealing member (4) for sealing the opening (12) of a vessel body (11); pressurizing member (6) linked to a retaining part (5) for sealing the sealing member (4), for bringing the sealing member (4) in close contact with the opening (12) all the time, wherein when pressure is applied, the pressurizing member (6) lifts the sealing member (4) against the biasing force of itself to open the vessel (1) and, when the pressure is eliminated, the pressurizing member (6) returns to position by the biasing force to close the vessel (1) by the sealing member (4); and a cap body (3) capable of mounting the sealing member (4) and the pressurizing member (6) to the opening (12) of the vessel body (11) containing a reagent. The reagent is collected using the cap structure.
