Nitrogen Liquid

Dispenser

  • Liquid nitrogen is available to authorized personnel from a dispenser on the B level at the confluence of Latimer, Hildebrand, Giauque, and Tan Halls. The product is dispensed into customer-owned dewars.
    • Teaching/research units receive recharge billing monthly for liquid nitrogen received from the dispenser. The current recharge rate is shown on the Cryogenic Plant price list. For billing problems, call Ext. 2-4165.
    • For problems with the dispenser, call Ext. 2-4165 or Ext. 3-3169. Other Emergency contact numbers are posted on the door to the Nitrogen Dispenser.

Authorization requires:

  1. Completion of Cryogenic Safety Training.
  2. Possession of an access card issued by the College. (Cal 1 card)
  3. Prerequisite training to be completed prior to sending email request for training and getting access programmed.

Process for training and requesting dispenser access:

(A) Go to the UC Learning Center online and complete the EHS 109 Cryogens Safety Training.
(There are two Cryogen Safety Trainings, please make sure you complete the EHS 109, the UCP course is not required.)

(B) When you have completed the online training, go into the Transcripts and Certificates icon online and either email me or print a copy of the training certificate and bring it to the dispenser for the hands on demonstration.

(C) I normally do the hands on demonstration and enter your information into the system by appointment only.

(D) The hands-on training is done in the four corners area at the College of Chemistry Nitrogen Dispenser.
(At the confluence of Latimer, Hildebrand, Giauque, and Tan Hallsadjacent to the Tan Hall freight elevator.)

(E) You will need to bring your Cal 1 card to the training.

(F) You will need to know your speedtype so the nitrogen you fill will be charged to the appropriate group.
(Ask someone in your group if you do not know this, or have the name of someone in your group so I can look it up.)

  • The training takes 10-15 minutes. Trainings typically take place between 9:00 AM- 4:30 PM between Monday through Friday at a mutually agreed upon time.

  • Email swilliams5117@berkeley.edu once steps above have been completed.

Bulk

Bulk liquid nitrogen is provided to the Physics Department and is recharged to that Department. The current recharge rate is shown on the Cryogenic Plant price list.

Nitrogen Gas

  • Nitrogen gas is piped into many teaching and research laboratories in the College. For problems with this piping, call Ext. 2-4165 or Ext. 3-3961
  • Teaching/research units receive recharge billing monthly for nitrogen gas based on monthly meter readings. Some meters are shared by groups and the charges are prorated. The current recharge rate is shown on the Cryogenic Plant price list. For billing problems, call Ext. 2-4165.

Helium Liquid

  • Liquid helium is available to teaching and research laboratories in the College and the Physics Department by placing orders at the Cryogenic Plant at BG9 Giauque, by calling Ext. 2-4165, or by ordering with the online Helium Order Desk. The liquid helium is available in 60, 100, 250, or 500-liter dewars. Orders must be placed at least 24 hours in advance.
