Submit a Sample

You would like to submit a single crystal sample to be measured by the X-Ray facility? Contact one of our scientists, we will find a solution! 

To process your request successfully, we need some information from you:

 

  • Please do not dry your crystals! Leave them in their mother liquor. 
  • Close your flask tightly to prevent solvent evaporation. Parafilm is useless!
  • Your telefone number and email adress
  • A sample name
  • a proposed structure
  • a brief description of the synthetic route and all solvents used
  • is the compound unstable against air or temperature?
  • should the absolute structure be determined? (e.g. for chiral compounds)
  • are there any special needs?
  • Download X-ray oder form
