Abstract
The present device is directed to a reagent transfer device for transferring a plurality of reagent samples from one location to another location having a deposit surface. The device includes a reagent tray having a top surface with a top surface area and a plurality of wells in the ratio of at least 1,000 wells per square centimeter of top surface area, and a transfer member having a transfer surface with a plurality of pins extending therefrom. Each of the pins is positioned to correspond to one of the wells so that when the transfer member is moved in the Z-direction the pins are simultaneously dipped into the corresponding wells. The device further includes a mechanism for moving the transfer member between a first position in which reagent from the wells is deposited onto the corresponding pins and a second position in which reagent on the pins is deposited on the deposit surface. The mechanism for moving is adapted to move the transfer member in the X-direction, the Y-direction and the Z-direction.
