glove-box specific suggestions (plus combination thereof) in addition
to standard cryo tips:
move the microscope out of the way
adapt scope appropriately
get another microscope
practice using your left hand
use a larger crystal-containing drop and loop you can see without a microscope
try a smaller hemispherical dewar
move scope into the bigger area (I looked at http://www.belletechnology.co.uk/ )
nix the pucks
use capillary-mount - frozen if possible (e.g.
http://scripts.iucr.org/cgi-bin/paper?S0021889801003697)
use a vinyl Coy chamber which allows overall flexibility.
