Dear all,

We are working on a Category 3 protein which must be contained so we have our crystals mounted in a loop and then covered with a plastic Mitegen cover which is glued in place. We're currently collecting at room temperature, but wondered if anyone has any experience of using a contained system at low temperatures? Any attempts I've had so far at freezing through either the plastic or a glass capillary have resulted in formation of ice on the surface so it is not even possible to see the crystal to centre it.

Best wishes,

Becky
