Abstract
Trays comprising a base have a plurality of axial slots adapted to receive buffer or other medical solution containers within the slots. A spring or other compression element at the bottom of the slot is configured to engage a plunger at the bottom of the solution container when present in the slot so that pressure is applied to the contents of the container in order to stabilize the contents while the containers are sterilized at an elevated temperature.
Claims8
A method for sterilizing a container filled with a medical solution comprising a buffer, which solution evolves vapor when heated, said method comprising:
- providing a sealed container having an open interior filled with the medical solution, a needle-penetrable septum, and a plunger;
- applying a pressure above atmospheric pressure to the medical solution within the sealed container by engaging a compression member against the plunger;
- and
- exposing the container to an elevated temperature sufficient to sterilize the medical solution within the container,
- wherein said temperature is sufficient to evolve the vapor at atmospheric pressure, and the applied pressure is sufficient to inhibit the evolution of the vapor within the container without precipitating the buffer.
