Re: dedicated circuits for automated microtomes and ultramicrotomes
To expand: maybe not really "yes, dedicated, each circuit to its own
ultratome" as a *requirement*, the ultratome power supplies might be
good enough to handle noisy power lines, power dips and fluctuations,
and the like, but ... ultratomes are expensive, and sudden surges and
brownouts can cause problems, as can outages. It's relatively cheap
to add circuits, especially in the planning stage, much cheaper than
after the fact power conditioning, so plan on dedicated circuits.
Overplan, in fact. At this stage, you have the opportunity to plan
for *lots* of dedicated circuits, whether they're needed or not. Put
them in now, and you'll have more flexibility in where you place your
equipment, and better power for future needs.
A more critical question is: do your ultratomes need isolated
grounds? This requires more planning, as the ground line for the
equipment has to be isolated all the way back to -- or beyond -- the
main power distribution center, not just the local circuit box.
Isolated grounds (to prevent ground loops) are critical for things
like electron microscopes, but I don't know how important they are
for ultratomes. The manufacturer can tell you if they are needed for
But again, needed or not, the planning stage is the place to put in
things like isolated grounds, and the costs are much lower than doing
it later when the need arises, so why not do it now?
