I have an experiment involving dozens of extractions coming to completion soon, ranging from pipe blends to cigars, and also a range of individual leafs. I've decided this round to use a vacuum filtration apparatus. However, I am undecided on filter media.
Whatman has a series of cellulose filters I am leaning towards, starting with larger micron rating and eventually going down to grade 5, which is 2-3 micron.
I was interested in possibly going down to 1 micron but that would involve borosilicate filters.
My question is related to the safety of different filters. A lot of these filters are for lab use, not necessarily vaping. For example, Whatman cellulose filters come in a variety of ratings, such as general purpose, qualitative, quantitative, or ashless. Anyone familiar with Whatman and have a recommendation?
Also, regarding borosilicate filters, I wonder if trace borosilicate fibers end up in the finished extract and if these pose a risk? There are binder free borosilicate filters or filters with binders. I am wondering which is more suitable?
Finally, I wonder if there is a consensus at what micron level to filter down to?
Thanks,
