Summary of material constraints

Lab members wishing to introduce new materials into this system must first obtain authorization from staff. New material requests must be initiated by submitting a Process Review Request form.

Non compliance will result in loss of member privileges


  1. Any sample that will outgas under vacuum (check with staff if uncertain). This includes but is not limited to samples containing elemental sulphur or phosphorus
  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.
