The Good
Because the plate is from sarstedt you already know the basic properties of the plates. We compared several plates from different companies before choosing the Facellitate plates for spheroid generation. The spheroids not only form a lot quicker compared to the other distributors. The imaging qualities are very good as well. There are a lot less scratches or other flaws in the wells. So far we haven't had issues with the plates from Facellitate.
The Bad
The only slightly negative thing about the plates is the casing in which they are provided. There are 5 plates packed in one package. The packages are sealed with a "clip" line like for freezer bags. You really have to be careful when closing them because otherwise the rest of the plates inside the package get "unsterile".
The Bottom Line
Very good plates, the coating works pretty good for spheroid generation and evaluation per live cell imaging. I would definitely recommend these plates.
