What is available?

We have a campus-wide site licence that includes all current students, faculty, and staff at Stanford.  This agreement includes the desktop version of ChemOffice Professional (PC) and ChemDraw Professional (Mac).  Our agreement includes the PerkinElmer Signals Notebook Individual Edition, a cloud-based electronic notebook, ChemDraw Cloud, and access to the personal edition of ChemACX, a supplier catalog with over 10 million compounds that is available on the web. ChemDraw can be used for searching SciFinder and Reaxys.  Mnova ChemDraw Edition is also included with ChemOffice Professional.  Learn more about what's new.

After installing the software on a personal computer, users do not need to be connected to the network to use it.   The software is also loaded on the cluster computers located in libraries, dorms, and computing clusters.  The current license agreement expires December 30, 2021.

Use Signals Notebook Individual Edition for free

PerkinElmer Signals Notebook Individual Edition, an electronic laboratory notebook (ELN) that is a cloud-based application, is included in our campus-wide site license for ChemOffice Professional.  This means that students, faculty, and staff at Stanford are able to use the Signals Notebook without paying any fees.  More information about choosing and using an ELN is listed at the bottom of this page. 

PerkinElmer has integrated its ChemACX supplier catalog so that when drawing structures with ChemDraw Cloud (but not in Experiments) in the Signals Notebook, users are able to get supplier information. See the September-October 2018 issue Signals Notebook - What's New.
