The Unipuck gripper is intended to mount and unmount samples stored inside Universal pucks v1 onto a goniometer (dry mounting). This gripper can operate with Spine caps and similar magnetic caps as, for instance, CrystalCap ALS or Hampton CrystalCap.

Two different Unipuck grippers are available:

• A magnetic gripper 
  Intended to operate with an electro-magnet or a permanent magnet with a low magnetic force
• A cryotong-type gripper
  Intended to operate with a permanent magnet with a high magnetic force. The goniometer head should have a sufficient clearance to enable the sample grabbing.

Both grippers can be single or dual ones.
