Dewars and VGL's

Dewars are storage containers used to contain liquefied gases such as Nitrogen, Oxygen, Argon, and Carbon Dioxide (CO2). These gases are in a liquid state and range in temperature from -290 below zero degrees to -125 below zero. At this temperature, the liquid is very dangerous upon contact with human skin. Dewars contain these liquefied gases safely starting with our dewar flask models and on up to our large bulk models. Ratermann Manufacutring carries lab type 4 liter through 50 liter. Our industrial and medical tanks, manufactured by BTIC (4L) have a working pressure up to 500 PSI and range from 180 liter to 265 liter. These tanks are D.O.T rated for road transport (4L).
