Abstract: There is provided an autoloader apparatus and skin testing system for rapidly loading a multi-headed applicator used for epicutaneous application of biological testing agents, while at the same time, effectively inhibiting cross contamination of testing agents during loading and removal of the applicator. The autoloader apparatus includes a plurality of reservoirs for storing testing agents therein. Each reservoir includes a collar defining an open top. The autoloader apparatus further includes a receptacle having first and second surfaces defining a plurality of apertures therethrough for at least partially receiving the collars of the reservoirs. The skin testing system includes an applicator and an autoloader. The applicator has a plurality of picks for sealably engaging the open tops of the reservoirs of the autoloader to enable each pick to be loaded with an effective amount of testing agent.

Abstract: An improved head is provided for an apparatus which places a stopper in the opening of a filled container. The head has a sleeve which includes an inflatable bladder for receiving the end of the filled container and for temporarily sealing the periphery of the container around the opening. A housing is disposed over the sleeve. The housing has a top surface and defines an access passage which communicates between the top surface and the inside of the sleeve. The stopper is subsequently inserted into the container through the access passage. The housing defines a chamber around the access passage, and the chamber communicates with the access passage. A conduit projects from the housing top surface in communication with the chamber, and vacuum can be drawn through the conduit.
