I am working on Diene Halogenation 2 in the Synthesis Lab for Organic Chemistry, and several classmates and I are not seeing any dots on the TLC plates. We are clicking and dragging the TLC plates to our solutions before, during, and after the synthesis of our desired product, but have no way of finding our Rf values for our lab assignment because no dots whatsoever are appearing. Is there a way to fix this?
Thanks for reaching out! Check out our other community post as to why those spots aren’t showing up on your TLC plate:
We have made some updates to our software, though! The starting material likely won’t show up on your TLC plates, but the product should. If it’s not, you’ll want to update the version of your lab. To do that, follow the directions below:
Keeping your labs up to date is important to remove any bugs we’ve discovered in the software as well as allow you to receive any feature updates we release.
The first thing you’ll want to do is delete the current version of your lab. DO NOT DELETE THE CONNECTOR! However, you will want to close the connector first. If you are on Mac, you’ll see a flask icon at the top of your screen, click on that then select quit. For Windows, the flask will be in your tray, usually in the bottom right corner. You may have to click the arrow to reveal more apps in the tray, but once you see the flask, right click on it and select quit.
- If you are on Windows - open a file browser, go to your C: drive, go to Program Files, find the “VirtualChemLabWin” folder (or whichever lab you want to update, it’ll have the format of VirtualSubjectLabWin) and delete that folder.
- If you are on Mac - open your applications folder and drag the lab you want to update to your trash folder.
Next, log in to portal.beyondlabz.com and click “Install” on the lab you just deleted. The most up-to-date version of the lab will be installed on your computer and you’ll be good to go!
