RE: Trimming around edge of cassettes

True, but only if the embedding centre isn't in use at the same time. Our problem was and still is, that it often takes over an hour first thing in the morning to embedd all our cassettes. So if we were to use that approach either we make the time to embedd longer by using the embedding centre to remove the excess wax, or we use the Paratrimmer so we can start sectioning straight away and don't delay the embedding. That way we speed up the turnaround times for our cases.
Another advantage of using such a device as the Paratrimmer is that there's no risk of accidentally scraping the number off the cassette. (which I've done on several occasions).
