A Universal Reagent Reservoir (URR) is a laboratory device that allows the storage and dispensing of multiple reagents in a compact, automated and controllable manner. The URR typically consists of a multi-channel pipetting device and several reservoirs or vials, each filled with a different reagent, that can be dispensed in a precise and repeatable manner.

This makes the URR an efficient tool for high-throughput applications in various fields such as biochemistry, molecular biology, and chemical synthesis. The URR can be programmed to perform specific protocols and can also be integrated with other laboratory instruments to form a complete automated workstation.
