Hello felow MO crystallographer,

For all it's worth, a while ago I've compiled a little document which
describes mounting needles. I've converted it into PDF and posted it here:

the sand were stone"

Dear CCP4,

I'm looking for advice on mounting thin needles for low temperature data
collection. Our needles are fairly long (100-200 microns) but only 20
microns or less thick. When I pick them up with Hampton loops (0.05-0.1 mm
size), the crystals tend to break as they are moved out of the drop and
through the liquid-air interface.

I see that Mitegen sells MicroLoops E, which are advertised as working well
for mounting needles. Can anyone recommend them? Can anyone recommend
Mitegen MicroMeshes or another tool for mounting needles?

Thanks,

Jack Tanner
