Shipping dewars containers of liquid nitrogen or crystals frozen in propane, freon, or ethane are consider hazardous shipments.
The shipment of all samples, chemicals, dewars, etc. must abide with all DOT and IATA regulations, the failure to do so may result in a delay or loss of your shipment along with possible fines. Argonne National Laboratory has obtained a letter of competent authority from the US DOT for the legal shipment via air transport of macromolecules frozen in propane, freon, and other flammable and nonflammable gases when packaged in a dry shipper. Please refer to: http://www.aps.anl.gov/Safety_and_Training/Tech_Updates/tud25.html
APS Technical Update (TUD-25).
Transport (including hand carried packages) of all hazardous materials to Argonne should conform with applicable regulations of the U. S. Department of Transportation. We call your attention to regulation 49 CFR 173.4 that has only minimal requirements for shipping small quantities of hazardous materials. Please refer to: http://www.aps.anl.gov/Safety_and_Training/Tech_Updates/tud23.html

Your university or institute’s shipping department should be able to provide further assistance on outgoing shipments.
If you have any special instructions for the SBC staff for the handeling of your dewars upon their arrival such as: email notification upon your dewar’s arrival at SBC, filling dewars with liquid nitrogen, placing packages in coldroom or freezer, etc., please notify Stephan Ginell by email Ginell@anl.gov , office phone (630)252-3972 or Michelle Radford email firstname.lastname@example.org , office phone (630)252-0560.
Liquid Nitrogen systems 80 – 300K
The sector 19 beamlines operate an Oxford Cryosystem or Oxford Instruments Cryojet for crystal cooling. It is routinely operated at 100K but can be set to a lower value if required. The temperature at the crystal is approximately 100 +2K at the crystal.
Liquid Helium systems 15 – 100K
SBC has available a Cryo Industries, INC. CRYOCOOL-LHE liquid helium cryosystem for ultra low temperatures. This cryosystem is not routinely available. Please contact Stephan Ginell by email email@example.com or phone (630)252-3972 for additional information and arrange scheduling.
