Standard vessel (model FD-800) : This vessel, which holds 800 ml of liquid nitrogen, is our most popular model. It replaces a large sized low profile glass Dewar. The foam dewar has superior durability, safety, and thermal insulating properties.
The standard vessel shape is circular, with a protruding handle, so that it resembles a large teardrop., as shown in the above photograph. Each bowl comes with a matching foam lid to insulate the contents from ambient air.
The price per unit is $100. Dimensions of the cylindrical cavity in this vessel are 5.8 inches in diameter by 2.8 inches deep, so that it easily holds 800 ml of liquid nitrogen.
Small vessel (model FD-500): [Newly introduced in July, 2007] This vessel is shown in the picture below, to the right hand side of the standard 800 ml vessel. As the photo shows, it has the same basic shape and features, but with a smaller diameter cavity.
(Standard) (Small)
The price per unit of the small vessel is $80. Dimensions of the cylindrical cavity are 4.5 inches in diameter by 2.8 inches deep, so that it easily holds 500 ml of cryogenic liquid.

Like the standard cryogenic foam dewar, the tall dewar offers durability, safety, and convenience for processing samples, especially when transferring from conventional shipping Dewars. The insulating properties of the Spearlab tall foam dewar are comparable to those of conventional stainless steel and glass Dewars, at a fraction of the cost. . Price per unit, with lid, is $160. This vessel has a 3.5-inch cylindrical cavity, 12.5 inches deep , which gives it a capacity of 1800 ml liquid nitrogen. The outer profile is a tapered octagon, as shown in the above photo.
