Liquid nitrogen dewar flasks hold and transfer liquid nitrogen at -196 C in the lab. Double-walled vacuum insulation limits heat transfer. A well-sealed lid slows evaporation, and a neck tube allows smooth, safer transfer. Two sizes are available. The 2 L flask stands 245 mm tall, and the 5 L flask stands 395 mm tall. Both have a 220 mm outside diameter and a 155 mm opening. Stainless steel resists corrosion. Match flask size to daily use. Wear face and hand protection when pouring liquid nitrogen. The 155 mm opening suits pouring. Check opening size against sample holders. Typical uses include sample freezing, cryogenic transfer, cold traps and teaching laboratories.
