New Releases

  • The data panel settings dialog now persists for the users applied search filter
  • There is now a help link for the spectrovis panel. It goes here:

https://www.adinstruments.com/support/documentation/using-spectral-analy...

Improvements

  • Analytics button placement has been moved to next to the Content Library button

Technical

  • KCDA v1.10.2 - a new SSL certificate valid for the next year is available. The SSL certificate is used to secure the communications between Lt and KCDA. KCDA v1.10.0 and earlier have a certificate which expires 2021-10-22, at which point the older versions of KCDA will stop working with Lt. Customers performing manual updates of KCDA will need to update by 2021-10-22. Then automatic KCDA updates will happen when the computer is rebooted, or overnight

The in-person versions of the 19 Chemistry labs are available! 

Content

The Chemistry Collection was developed in partnership with Vernier and originally consisted of 19 Distance Learning labs, designed and released during the pandemic. We are now completing the collection by adding a further 19 labs, which address the same topics but are designed for in-lab use. The labs in the collection address fundamental introductory General Chemistry topics, and the majority (17/19) use Vernier's Go Direct sensors to collect data in Lt. All of the labs have some form of example data to enable flexible teaching.
