Pucks and Tools
Caps
We recommend Hampton Research product CrystalCap Magnetic ALS HR4-779 and the accompanying vials HR4-904.
The Crystal Cap Magnetic (shown on the left) is unacceptable. Note that the correct base (on the right) has no horizontal lip when transitioning from the sloped area to the vertical, critical for proper robot functioning.
Loops
We recommend LithoLoops from Molecular Dimensions Ltd. All loops from MDL have a pin length of 18mm, the recommended pin length at NECAT.
Other loops are acceptable, but it is highly recommended that a pin length of 18mm is used, as this is the length the robot is optimized for. Additionally, be sure that all pins are firmly and perpendicularly posted, as this will make for much more consistent and efficient mounting and centering.
How to load pucks with crystals
It is easiest to load pucks as one loops and freezes crystals.
- Freeze as normal and place directly into the cryo puck.
- When you finish loading the puck, place the magnetic cryo puck lid onto the cryo puck, being careful to line up the shaft (notice the 'D' profile) correctly.
- Once you have the lid in place, push down on the lid using the puck pusher.
- Place the cryo puck and magnetic cryo puck lid sandwich into the cryo puck shipping cane using the 10 inch cryo tong and put it into LN2.
