Can I exchange data between my contract laboratory and my laboratory ?

Provided you are using Debra 6, you can import data from any Debra database including Debra 5, enabling further analysis and reporting of studies run at your CRO as well as the ability to pool samples for metabolite profiling.

What instrumentation can I link to Debra ?

Typical instrument links include balances and liquid scintillation counters.  Any balance with an RS232/USB or Bluetooth connection can be linked to Debra, likewise all vintages of liquid scintillation counter can be interfaced to including Packard/Perkin Elmer Tricarbs, Hidex 300SL even your old standalone DOS based Beckman counters.

How often are there updates to Debra ?

  • Updates to the Debra program usually occur 1 to 2 times per year. Updates to the program are usually a result of comments and suggestions from our network of clients. In addition, our programmers are constantly improving the program to simplify functions even more.  When an update is installed, we include software release notes for your records, a summary for the changes made and how it may effect validation considerations.
  • LabLogic operates a policy of not forcing clients to upgrade to the latest release. This enables sites that are happy with a current release to continue using there validated version until such time as they feel there is a real benefit to be gained or when it is more convenient.

Can I upgrade my data from Debra 5 to Debra 6 ?

Yes, full instructions of the upgrade path from Debra 5 to Debra 6 are available from our support team.
