An optimal system makes efficient use of a purchasing strategy while minimizing interference with teaching and research functions. The system can include information about the kinds, quantities, location, and status of chemicals within a particular laboratory or facility. Tracking a chemical from purchase to disposal can benefit the institution by reducing duplicate purchases. By allowing for redistribution of surplus materials, careful inventory control also minimizes the waste generated from partially-used containers of chemicals that age on laboratory shelves and the accompanying risk of accidents. A comprehensive approach to chemical management requires substantial information and a modern file or data management system.
Some laboratories use data networks, tailored to the needs and resources of the respective facility.
The costs of the computer hardware and software needed for such a system have dropped dramatically over the last decade. A bar code inventory system has proven to be effective at some facilities- particularly when a centralized storage and data management system is used. This system allows tracking of the container as it moves throughout the organization. A computer inventory then can be made available to laboratory workers, who may search the database by chemical formula, chemical name, trade name, and location of the container. Tracking purchases with a computer database can provide significant savings by facilitating a storeroom's efforts in redistributing surplus chemicals, preventing the materials from prematurely becoming waste.
