Abstract

A removable secondary liquid dispensing module for use with an existing, automated liquid handling system that defines a work area having a plurality of discrete work stations. Each of the work stations of the automated liquid handling system includes a lab ware site and alignment structure enabling the removable securing standardized microtiter-plates at respective lab ware site. A plate positioning mechanism is configured to move and position the microtiter plates to and from the lab ware sites of the respective work stations thereof and into engagement with the respective carrier alignment structure thereof. Further, a primary liquid dispensing device is configured for selective contact-type dispensing of discrete quantities of fluid, in the range of about one (1) microliter to about ten (10) milliliters, into the test sites of the microtiter plates secured in the respective alignment structure of the respective work station. The removable secondary liquid dispensing module includes a base member dimensioned to fit substantially within a footprint of a work station, and mounting hardware adapted to removably secure the base member in the work station. A support platform is affixed to the base member, and is configured to support a microtiter-plate. An alignment mechanism is configured to removably receive and secure the a microtiter-plate therein by the plate positioning mechanism of the automated liquid handling system. The support platform and alignment mechanism cooperate to form and provide a lab ware site suitable for secured receipt of a microtiter-plate. The secondary liquid dispensing module further includes a secondary liquid dispensing device which is self-contained and operationally independent from the primary liquid dispensing device. The secondary dispensing device is further adapted for selective non-contact-type dispensing of discrete quantities of fluid, in the range of about one (1) nanoliter to about ten (10) microliters, into the test sites of the microtiter-plate.
