A multiple probe liquid handler includes a syringe pump assembly with multiple syringe pumps communicating with the probes. A carriage movable with respect to a fixed support base carries syringe pump pistons moving within syringe pump cylinders secured to the base. A drive system including a single drive motor has a single drive point connection to the carriage for moving the carriage and operating the syringe pumps in order to draw fluid into or discharge fluid from the multiple probes. A linear motion support assembly includes spaced rails attached to the support base and slides attached to the carriage and riding along the rails. The assembly includes two parallel rails and three slides, one riding along one rail and two riding along the other rail, providing an inexpensive yet imbalance tolerant three point support.
