Dewars

The LAB series dewars use high efficiency super-insulation and aluminum construction to make them lightweight and the most efficient containers available. Their shape and handles make them easy to lift and pour. The Lab series dewars can also be fitted with pouring spouts, Withdrawal Devices (as Shown above on the LAB 50) or dippers to aid in the liquid nitrogen transfer.
