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, as shown in the photograph on the left. Each dewar comes with a matching foam lid to insulate the contents from ambient air. The price per unit is $100. The cylindrical cavity in this vessel is 5.8 inches in diameter by 2.8 inches deep.
This is a slightly bigger version of the popular standard vessel. The price per unit of the large foam dewar is $160. Dimensions of the cylindrical cavity in this vessel are 6.3 inches in diameter by 3.8 inches deep, so that it easily holds 1400 ml of liquid nitrogen.
This vessel is shown in the picture on the left. As the photo shows, it has the same basic shape and features, but with a smaller diameter cavity. The price per unit of the small vessel is $85. 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.
The tall dewar, can be used as a replacement for upright glass or stainless steel Dewars. Originally, this vessel was designed for short term storage of canes of protein crystallography samples. 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. The price per unit, with lid, is $180. This vessel has a 3.5-inch cylindrical cavity, 12.3 inches deep , which gives it a capacity of 1800 ml liquid nitrogen. The outer profile is a tapered octagon, as shown in the photo to the left.
The model FD-130 is our smallest foam dewar. In the photo to the left, it is the smaller of the two vessels shown. The price is $50. The cylindrical cavity in this vessel is 2 inches in diameter by 3.5 inches deep, so that it easily holds 130 ml and a maximum volume of 175 ml of liquid nitrogen. Perfect for dermatology and other applications that require a small quantity of cryogenic liquid.
