Care of Uni-Pucks
It is important that the Uni-Pucks be checked before each use as constant freeze-thaw cycles can lead to loosening of parts which can result in sample loss. NE-CAT does not guarantee sample recovery or beamtime if faulty Uni-Pucks are used or if the wrong kind of pucks are sent to the beamline.
Sample Enclosure (Top/Lid)
- Always ensure this is warmed up, dried and clean between uses.
- Always check the enclosure and remove any metal debris (e.g. broken pins)
- Pins are held in place by NdFeB ring magnets secured with polycarbonate washers.
- Replacements can be obtained from Crystal Positioning Systems:
- Ring magnets: CP-111-006-020
- Washers: CP-111-007-020
- Replacements can be obtained from Crystal Positioning Systems:
- The top of the sample enclosure is fixed with four Philips head screws which should be firmly secured.
Puck Base (Bottom)
- Always ensure this is warmed up, dried and clean between uses.
- Always check the base and remove any metal debris (e.g. broken pins)
- The base spindle is held in place by a philips head screw which should be firmly secured so that the spindle cannot twist.
- The base is secured to the enclosure by clips held in place with flat head screws. The screws should be secure and the clips bent so that they grip the sample enclosure snugly.
- Replacement clips are available from Crystal Positioning Systems (CP-111-043-20)
