Instrument Scheduling 

If you have completed the steps for lab access, you may reserve instrument time here

Note on liquid nitrogen and specialty gases:
You will need to supply your own tanks for these gases. To have gas tanks shipped to the MCL, use this information: 

Address:
420 Kelly Hall
325 Stanger St
Blacksburg, VA 24061
United States 

Location code: 123533
Building code: T493

Plan your tests to use most or all of the tank you ordered. The MCL is a shared facility with limited space, and while it will not be possible to reserve tanks for individual users, you will be alerted when your tank has arrived and have access to it before other users.  

Once you are notified that your liquid nitrogen has arrived, reserve instrument time via the online reservation system. Please use your tank as soon as possible, and then promptly request its removal by the vendor to make the space available for other users.
