A method for reducing or eliminating the aspiration of foam into a metering probe includes the steps of providing a reagent supply container having a baffle having sealed ends and having a liquid reagent in it. A metering probe movable in a direction toward and away from the reagent supply container is provided. A closure is moved away from the opening of the container and both seals covering the first and second openings of the baffle are pierced allowing liquid to enter the baffle from the end of the baffle submerged in the liquid thereby providing a foam reduced or foam free zone. The metering probe is moved into the first opening of the baffle and into contact with the liquid in the baffle. A selected amount of liquid in the baffle is aspirated and the metering probe is moved out of the baffle.

Containers for reducing or eliminating foaming

There is described a package and method of packaging that provide, in inexpensive form, means for adding accurate amounts of one material to another. The package, which can come as a kit to be added to a lyophilizing bottle and stopper, features a portion that is added to the bottle outlet to confine the material that is to be stored separate from the contents of the bottle. That portion includes a plunger preferably constructed to provide a dual function: that of sealing the stopper against the bottle outlet, and of permanently attaching to the stopper to remove it from the bottle when the plunger is moved within the upper portion. Because of its hollow configuration, the plunger can be used to pour off the resulting mixture.
