I'm looking to purchase 1 liter of liquid nitrogen specifically for health-related purposes. It would be great if you could provide me with the pricing details for the minimum order quantity, including the cost of the container. Additionally, if you have any recommendations for suitable containers for storing or transporting the liquid nitrogen safely, I would appreciate that information as well. Thank you for your assistance!
