ABSTRACT:
A fraction collector wherein a head is aligned in sequence with individual containers of an array of containers so that fractions or samples may be deposited into the containers from a delivery tube supported by the head. A table surface slidingly supports a number of racks holding rows of containers. The racks are releasably attached to spaced points along a chain moved by a chain drive motor around a closed loop above the table surface. The head is supported above the path of the racks and is moved across the racks and along the rows by a head drive motor. A control circuit controls the chain and head drive motors to advance the chain in increments to position successive rows beneath the head, and moves the head in increments along the container rows to position the head above individual containers.
