The real, or “life-cycle”, cost of a chemical includes its initial purchase price plus the ultimate disposal costs. Keep the quantity of accumulated chemicals in the laboratory at a minimum to reduce the risk of exposures, fires, and waste disposal problems. Smaller package sizes provide the following advantages:

  • Reduced storage hazards
  • Reduced storage space
  • Safety in handling smaller quantities
  • Reduced losses due to out-of-date chemicals
  • Minimized cost of disposal of “leftovers”

Frequently, it costs many times more than the original purchase price to dispose of leftover chemicals. Chemical storerooms on campus keep supplies of the most frequently used solvents and chemicals to lessen the need for laboratory stockpiles.
