NEW:   UltraScan III  version 4.0! Versions beyond 2600 take advantage of 1-second-interval TimeState information from the new Optima AUC ultracentrifuge to achieve greater accuracy in finite element modeling; and add other important enhancements (read the announcement). The recommended version is now v4.0, Release >= 2600.

There is a recent change in Instrument Configuration that relates particularly to database instances where the lab includes one or more Optimas. In the past, configuration was on a per-user basis. Now, the Optima and other instrument configurations are in the database and are on a per-instance basis. From revision 2625 on, users may need to reconfigure lab instruments, including Optima Host(s), via the desktop Preferences -> Instrument Preferences dialog.

Version 4.0, 64-bit: 4.0 Archive Version 3.5, 64-bit:

Special MacIntosh Notes

The most recent installations for MacIntosh are 64-bit only. All Apple desktop/notebook hardware of the last several years is 64-bit, so this should not cause a problem. If you encounter problems with the software that may be related to 32-bit/64-bit issues, please inform us. We can build a special dual-architecture version.
