Self-sealing reagent container and reagent container system
 Self-sealing reagent container, and a system of same on a carousel, related to a vessel having a plurality of separate compartments, each compartment having an opening in an upper surface of the vessel, with a hinged lid member attached to said vessel having spring-like biasing to automatically reseal openings of the vessel after reagent extraction. The lid has a first arm that is normally biased such that its caps cover the compartment openings, but external force can be applied to said first arm to permit the first arm to be translated so as to displace the caps from covering the compartment openings whereby reagent in the compartments can be accessed and withdrawn. Once the reagent extraction is completed and the compartment opening cleared of the extraction device, the normal biasing acting on the first arm of the lid causes it to move back to reseal the caps over the compartment openings. The lid member is used with a ramp guide means to ensure alignment of openings and caps and provide vertical clearance of the first arm relative to the cover of the reagent vessel when displaced by external force.
