Interfacing apparatus between a laboratory automation system and a platform for handling consumables and liquids in the field of molecular biology
Apparatus for automatically filling wells of plates with biological material from a laboratory automation system for conveying biological samples or reactants contained in test tubes, and automatically routing said plates towards processing modules of said biological material. Said apparatus contains a platform interposed between said laboratory automation system and a handling system of consumable products, which includes a horizontal crosspiece whereon a first robot and a second robot are sliding mounted, the first robot being provided with gripping means of pipettes adapted to collect and release the biological material or the reactant, and a second robot being provided with gripping means of consumable products.
1. A method for automatically transferring biological material and reactants from a laboratory automation system for conveying a plurality of single test tubes containing biological material and a plurality of single test tubes containing reactants, to a handlings system for moving plates with wells with biological material to be tested,
wherein the laboratory automation system comprises a main lane and a secondary lane for conveying the plurality of said single test tubes and a stop gate at said secondary lane for blocking the plurality of said single test tubes,
wherein the handling system comprises means for moving the plates with wells to testing modules, and
wherein the method comprises the following steps:
in said laboratory automation system, conveying a plurality of said single test tubes containing biological material to be tested and a plurality of said single test tubes containing reactants for biological material to be tested towards a platform interposed between the laboratory automation system and the handling system, said platform housing plates and containers containing a plurality of new pipettes and comprising a horizontal crosspiece whereon a first robot and a second robot are slidingly mounted,
diverting a plurality of said single test tubes containing biological material to be tested from said main lane to said secondary lane of said laboratory automation system,
diverting a plurality of single test tubes containing reactants for said biological material to be tested from the main lane to the secondary lane of said laboratory automation systems,
linearly queuing a plurality of said single test tubes containing biological material to be tested and a plurality of said single test tubes containing reactants for said biological material to be tested, at said stop gate of said secondary lane,
by said first robot, gripping a linear sequence of new pipettes from a container by a linear sequence of fingers for gripping pipettes, moving said linear sequence of pipettes over said test tubes linearly queued at said stop gate of the laboratory automation system, collecting biological material or reactant from said test tubes after lowering said fingers into said test tubes, conveying the collected biological material or reactant over wells of a plate housed in a housing of said platform, releasing the collected biological material or reactant into said wells of a plate, and releasing the used pipettes into a basket of the platform,
by said second robot, gripping plates with wells filled with biological material to be tested and moving them to said handling system, gripping plates with empty wells from the handling system and move them to housings of the platform, gripping containers of containing a plurality of new pipettes from the handling system and moving them to housing of the platform,
said platform being also provided with a control board mutually communicating with a control board of the laboratory automation system, so that the number of the pipettes to be gripped by the fingers of the first robot is equal to the number of test tubes linearly queued at said stop gate of the laboratory automation system, the maximum number of pipettes being equal to the number of pipettes accommodated on the same row of the container.
