As someone who used to do preventative and emergency maintenance on -80 freezers, this hits hard. The number of nights I spent swapping samples from one unit to another because the first unit was failing was a lot... but it was automatic triple time.
We talking ThermoFischer Scientific, or others? Is there a reliable ULT freezer anyone can recommend?
Edit: also what were the common failures?
Absolutely real on the thermofisher one. We had one die once. I have a photo of it actively dying of death early this year. It's about to get carted off as we got a rebate for recycling our old freezers.
That day was funny bc I was able to leave early that day but I was waiting for my sister to finish her classes before we went home. So I was playing TF2 on my laptop using my work dock before my supervisor's supervisor walked in. Luckily for me she did not care.
We transferred all the samples to the one beside it.
Edit: I think that was the only -80 freezer that had issues and it was probably 15 years old when it died. The newer thermo Fisher isotemps seem to be okay.
