  2. Samples containing any degree of moisture, including soft plastic or hydrogels
  3. Geological samples
  4. Biological samples
  5. Magnetic materials of any type

  6. No outside or specialized custom sample holders (i.e. Protochips, liquid cells etc.) without specific authorization and consultation with staff.
