Lab-Line Instruments Thermo-Flask 16.5 Tall Liquid Nitrogen Dewar

  
I believe this to be a labline solid stainless thermo flask. It may be another brand of similar use. There is no lid for this container.

It is a very stout, heavy insulated flask with handle of equal stout making. The measurements are shown in the photos but its about 16.5 inches in height and 8 inches in total circumference. There is some type of pressure release valve in the lower bottom as shown and there is a logo on the cap. Not even sure exactly what the valve is for but assume for pressure.
