Abstract: A blood collection assembly and closure therefor, for the collection, separation, isolation and storage of serum from blood. The closure is constructed of a cannula penetrable self-sealing elastomer and includes a thixotropic barrier material in a hollow central portion of the closure, so that the barrier material is sealed within the closure until blood has been collected in the collection container and centrifuged. Centrifugation forces the barrier material into a collecton container through the passageway created by the cannula.

Abstract: The metered discharge of aerosol compositions from aerosol dispenser packs through an ordinary aerosol valve is achieved with precise control over both the amount discharged during each metered discharge operation and the specific time interval available between each metering operation by causing the aerosol composition to traverse a closed path from the body of the aerosol pack to the discharge orifice through a plug fitted into the tailpiece of the valve, the plug comprising a variable length of a reticulated porous polymeric material having an average pore diameter of less than 10 microns with the pore volume being between 10 and 50% of the plug. The plug is fitted to the tailpiece of the valve which enables uniform spray characteristics to be obtained.
