Description
The US Department of Agriculture (USDA) is seeking a quotation for an Auto Volume System, specifically the Titrator Excellence 7 or equal. The system will be used for routine and advanced chemical analyses to support phenotyping, quality testing, nutrient profiling, and research experiments. The contractor must provide a fully automated, high-precision titration system with seamless integration into laboratory workflows. The system must meet specific technical requirements, including potentiometric sensor inputs, polarized sensor input, and temperature sensor input. The contractor must also provide training operation for the Titrator Excellence 7 and Base InMotion Max, as well as extended care for these systems.
• The system must have a minimum resolution of 0.1 mV and an error limit of 0.2 mV.
• The system must have a measurement range of ± 2000 mV.
• The system must have a polarized sensor input with a measurement range of 0 … 2000 mV / 0 … 200 µA.
• The system must have a temperature sensor input with a measuring range of –20...130 °C.
• The system must have a burette drive with a resolution of 0.5 µL (1/20000 of the burette volume).
