Hi all,

My project is to analyse nitrous oxide (N2O) in gas samples. I bought and used a box of Labco Exetainer vials. Now I still have (many!!) more sampling days to go. Means, I have to buy more Exetainers!! Being an undergrad student, I dont have enough funding to buy these many Exetainers. Any suggetsions on how to create vacuum in my vials will be really helpful.

My Prof is happy to spend on a vacuum generation system rather than on Exetainers!!! Where can I buy "vial-vacuum generation system"?

Thank you.
