Total Lifetime Cost of a Chemical
Lab managers who purchase low-priced chemicals may not appreciate the true “lifetime cost” of a chemical. The lifetime cost includes not only the cost to purchase the chemical, but also the cost of storage and disposal. Cheap chemicals are typically lower quality and packaged in inferior containers. This greatly increases the amount of chemicals needing expensive disposal. Save money by relying on Flinn to provide smaller quantities of higher quality chemicals in date-labeled packages.

Alcohols and Explosions
Reports suggest that secondary alcohols, such as sec-butyl alcohol and isopropyl alcohol, can develop explosive organic peroxides. Organic peroxides are unlikely to be a problem if the alcohols are fresh. Solution: Always know the age of your chemicals (Flinn chemicals are all date-labeled), and use only fresh materials. Also, do not distill any alcohols to dryness since this will concentrate any explosive peroxides that may have formed.
