Reduce, Reuse, Recycle
If you work in a lab, you know how expensive some of the equipment can be.

The resources below provide good options for buying as well as selling old scientific equipment. That means that your lab can complete the reuse loop by purchasing items like microscopes, Bunsen burners, and beakers that have been used before.
