Luckily we have already been using the new workstations when I came across this. I had kept the incubator portion only of the older model like yours for back-up, and went back to using our smaller footprint, yet old, tube incubator block (can't imagine that relic is cleared either!). Once I saw that the old station was no longer FDA cleared, etc., I ordered a new tube incubator block. I am very curious to see if the old incubator can still be used (would love to still keep as back-up) since we always check and document the temperature.
