Understanding Liquid Nitrogen Pricing
Factors Influencing Pricing
When considering the cost of liquid nitrogen, several factors come into play:
-
Source of Purchase: Liquid nitrogen can be purchased from suppliers or generated on-site. Purchasing from suppliers often incurs higher costs due to transportation and delivery fees.
-
Volume: Bulk purchases typically lower the price per liter. Smaller quantities, especially those sold in cylinders, often carry a premium.
-
Location: Pricing can vary by region due to supply chain factors and local demand.
-
Application: Different applications may require varying purities or forms of nitrogen, impacting the overall cost.
Typical Cost Ranges
According to data from various sources, including insights from www.thepricer.org, the cost of liquid nitrogen in the United States ranges from approximately $0.15 to $1.80 per liter. For bulk orders, prices generally start around $0.55 per liter, while on-site production can bring costs as low as $0.15 per liter.
