We got a nice tabletop SEM loaned from a UC scientist for a short while.
I was going to demo it after the meeting but I had a school function I needed to attend.
I’ll be at the Hive Sat afternoon ~1-3pm to help demo what it can do.
Unfortunately I think it will only be here for a short time. She would like it back for the school year.
We may get it again if things work out.
I have a question: So you say “no wet or oily stuff.” Does that mean pond water samples are not acceptable?
If not, I have plenty of dry, non-oily things to bring in.
No worries. I talked about this briefly in the training but probably didn’t emphasize it enough.
The stage can get “stuck” at the edge of the travel.
All you need to do is evacuate the chamber, determine which direction it is stuck (far left or far right), gently push on the base of the stage (the part that moves) in the opposite direction while turning the left/right knob to move in that direction. You can press at the base of the sample shaft that the disc holders screw into. You should feel the stage “break free” and the knob should work again. Very little force is required.
There is a clutch on each knob that will slip if the stage gets bound up. The clutch seems to be able to drive in one direction slightly more than the other. So, one can move the stage to the edge of travel and are unable to move back.
If people are uncomfortable doing this I can swing by and take a look.
