The present invention provides an XYZ type laboratory robot to be used with various peripherals suitable for analyzing and/or preparing samples of liquid. The robot has a work surface (1) including a moving system (2) for supporting elements (7) required for analyzing and/or preparing the samples of liquid. The work surface is associated with an appropriate sample-taking device such as a needle (5) connected to an automatic syringe and displaced vertically on appropriate sampling arms (3, 4) so that the needle (5) can be displaced along three orthogonal axes X, Y and Z. The needle (5) can be inserted into an appropriate stopper member (8) temporarily secured to the elements (7) such that a bottom portion of the needle (5) actively cooperates with the stopper member (8) resulting in the stopper member (8) exerting frictional forces on the outside of the bottom portion of the needle (5) to temporarily connect one of the elements (7) to the needle (5). When the needle (5) is so inserted into the stopper member (8), the element (7) can be displaced from any point on the work surface (1) to other determined points relative to the work surface (1) by programming the movement of the needle (5). Additionally, the XYZ type laboratory robot can be provided with an identifying device to identify the elements (7) being displaced and/or filtering elements (11) that each include a filtering device (10) for filtering the samples of liquid injected into the element (11).
