One of Elston's rules for chemical inventory management: If you haven't used it for 3 years, you don't need it. Some exceptions apply, but they are rare.

There are a few other rules, such as "expiration dates probably aren't" for most purposes. I think Ralph hit a good point - you're taking up valuable lab space.

Our research lab is currently updating the chemical inventory. Other than bottles/containers that are broken/cracked, I'd appreciate any advice on discerning which chemicals can be purged or disposed of. Many of the chemicals are dated over 20 years ago, but I know of at least a few that have an indefinite shelf life.

Any guidance in this area is quite welcome.

Thank you,

Hannah Corcoran
