  • System for filling substrate chambers with liquid
    Patent number: 6942836
    Abstract: The present invention is directed to a system for filling sample chambers with liquid. The system includes a substrate defining the sample chambers and having a fill port, and a network of passageways connecting the sample chambers to the fill port. The system also includes a substrate support to retain the substrate in a fill position and a valve module on the substrate support. The valve module has a fill port seal opening to connect with the fill port of the substrate in the fill position, and a vacuum opening for connection to a source of vacuum. The system further includes a valve body having a liquid outlet port and a vacuum port, and means for operating the valve body so that the liquid outlet port and the vacuum port are alternately in fluid communication with the fill port seal opening.
