Our world-class collections are the heart of our free museum and library.

We collect and preserve a wide variety of historic objects, artworks, photographs, books, oral histories, videos, and documents that reveal how developments in the history of chemistry, chemical engineering, and the life sciences are embedded in our daily lives.


Visitors can view objects that uncover more than 500 years of scientific history in our free museum. Come see selections from our much larger collection, found in both our permanent exhibition and rotating temporary gallery. We’re open Wednesday through Saturday, 10am to 5pm. Or you can check out our digital collections 24/7.
