There is described a container used to extract antigens for an immunoassay, having a wall means defining open and closed opposite ends. The container is provided with dividing members located in the closed end of the container which divides the volume of the closed end into at least two separate regions. A portion of the container's wall means adjacent to the closed end is shaped and sized to cooperate with a depositing device to ensure that separate reagents are separately deposited on opposite sides of the dividing members.

Extracting device for extracting antigens

A control panel includes electronically addressable display means and a removable opaque overlay. The overlay has transparent graphics indicating machine options for primary functions. The machine options are selectively backlit by the display means to indicate a particular option. When the overlay is removed the display means operates in its conventional manner to guide the operator through more complex special features.
