The Soil Testing and Plant Analysis Laboratory requires a robotic workstation that is designed for the automated measurement of soil pH, featuring independently addressable X and Z axes, integrated probe systems, and customizable software. The system must be capable of performing parallel measurements of pH on multiple soil samples with options for buffer addition, incubation, and remeasurement. The workstation must provide automated data handling and user-defined protocols. Specifications: The pH robot must be able to accommodate and control eight pH probes, stirrers, and cannulas and simultaneously measure soil pH in multiple samples in parallel. It must also be able to export data directly to Excel. The instrument must have a driver library that allows for the integration of balances, barcode scanners, temperature controllers, and other external devices. The pH robot must fit on a standard laboratory bench with dimensions of 18”-24” x 45”-56” x 16”- 20” (W x D x H). The pH probes must be replaceable and there must be miniature mechanical stirrers for each probe. The pH buffer must be delivered by inert tubing such as Teflon cannulas. The syringe pumps used to deliver the buffer must be programmable and have an 8-port valve to dispense buffer to selected samples. The instrument must support racks currently used by the lab and be able to hold between 48 and 150 samples. The robot must also have a multi-port water jet for washing up to 8 probes and stirrers...
