Inquiry (采购产品): liquid nitrogen Hello, I am a high school science teacher in Janesville. I am looking for a local supplier of liquid nitrogen so that I can get some for some demonstrations. Do you sell LN? What is an approximate cost if so? And lastly, how would I go about picking some up? Thank you for any information you can give. **** Hidden Message ***** Rob Eastman 53548 Company: Janesville School District E-mail: reastman@janesville.k12.wi.us **** Hidden Message ***** reastman@janesville.k12.wi.us
