Liquid Nitrogen Delivery

Dewar Registration

As of May 2013, Facility Services manages all administrative activities related to the filling, replenishment and billing of tanks/dewars containing and transporting liquid and gaseous nitrogen. Liquid nitrogen transport dewars are to be registered with the FHS Safety Office. This does not include biological storage tanks, only those tanks which are transported in and out of the lab for filling.

Please complete this form to register and update information on your dewar. Once processed you will receive a Dewar Number. All queries related to liquid nitrogen billing and costs are to be directed to Krissy Estabrooks. As of March 2020 the prices for liquid nitrogen filling are:

PRICE ($/L) (Reg.)		$ 0.76	(Mon/Wed/Fri)
PRICE ($/L) (Spec.)	$ 1.20		(Tues/Thur)

Secure the information (Name, Location, Volume and Dewar Number) on the vessel using permanent marker or by other means.
