Firmware Update Notice 03/05/2024

This Firmware Update is ONLY for customers who have a Trilogy Laboratory Fluorometer with Firmware Version 2.0.0.  Customers with Firmware Version 1.3.3 or earlier will not experience any of the issues stated below and do not need to update.

You can find the Firmware version for your Trilogy if you go to the Diagnostics page:


A new Firmware version has been released addressing some issues you may or may not have encountered.  If you have not encountered any of the following issues and are using your Trilogy Laboratory Fluorometer without fault, you may NOT need to update your Trilogy with the latest firmware as the corrections are primarily related to calibration files saved to the Trilogy.

For those customers who prefer to update their Trilogy with new firmware, all updates have to be made at Turner Designs, so your instrument will need to be shipped back to our factory.  Please contact and we will issue you an RMA for the return of that instrument to be updated.
