<div>== Nomenclature ==<br />
<br />
The crystal sits in the loop, the loop atop a pin, which is attached, usually with superglue, to a base (most frequently magnetic). Hampton calls the whole assembly CrystalCap. Caps protected by a vial can be stored in liquid nitrogen.<br />
<br />
== Potential problems after mounting the cap onto the goniometer head ==<br />
<br />
* ice crystals at the bottom of the base - These will slowly thaw and move the loop away from the cryostream ==> use only dry caps for freezing crystals<br />
* loose pins in the base => superglue pin into base and let set before freezing<br />
* magnets too weak (base too heavy)<br />
* magnet too strong, leading to whiplash effect and catapulting the crystal from the loop (when freezing crystals directly on the beamline, not when mounting prefrozen crystals)<br />
* incorrectly fastened goniometer, magnet etc.</div>Docandreashttps://wiki.uni-konstanz.de/ccp4/index.php?title=Crystals&diff=1053Crystals2008-08-01T11:41:45Z<p>Docandreas: /* Crystal Growth */</p>
