Unsure if this is the most optimal place to post.

I am trying to find the best thing to use to purge water with N2. I have seen a lot of people use fritted glass and am curious as to how essensial this is to the process. Is there anyway to DIY or get a cheap one? Is nanometer essensial or could we make do with mm? We will be purging batches of approx. 1.8L for 30 mins. Currently the smallest we could go is 0.4mm, would this work?

We are trying to crudely replicate anoxic conditions of wetlands in our water samples and there will be high concentrations of arsenic.
