I have been interested in tossing a general microtome/sectioning question
out to the list and this seems like a good place for it to go:

If someone were to suggest that you needed to produce sections between 20
and 30 nm to use on a specific TEM to get results, is this a thickness that
most of you feel is attainable (albeit something of a challenge) or, in
fact, too challenging to be routinely considered ?

Thanks in advance for the feedback.

Hi Tim,
I have dhad the Microm HM 355 S for several years and asolutely love it! We
do many very tedious serial cuts of entire vessels, and the machine makes my
life so much easier. It is reliable, easy to learn, and thus far I have had
no problems. 
Best of luck!
