The size of grade 2 paper is equivalent to the size of Whatman qualitative grade 2
In agricultural science, soil prefiltration, fertilizer analysis, and seed test for nutrient absorption are common exercises.
Analysis of beer and malt, removing turbidity in wort, and yeast filtration - breweries test for these things
Filtration of the air and gas to monitor pollution of specific pollutants and
A high retention rate that allows fine crystalline particles (5*10 micron) to be retained without a fast flow rate.

Questions & Answers

Do you think this would be the right filter level to remove wax only from cannabis oil/ethanol when it has been winterized?

I'm not an expert in this process, but from literature it seems like grade 4 would be a good starting point Remove the bulk of the wax with a filter. To eliminate even the tiniest traces, grade 1 and then grade 2 are required. Have a look at the Tony3 review of this grade for an example of what would be eliminated in grade 1. As this is a growing application of our filters, I wanted to expand a bit on that. As wax filtration is slow, you need to use a large vacuum filter if you want to filter the wax effectively. While gravity filtration might work, it is arduous and will take a long time. The best way to improve speed is to start with coarse filtration (grade 4) and increase retention (grade 1 then 2). We have a cost effective bundle for most sizes if you are planning to buy all three grades. Search

If I drop a small amount of water on these filter papers, will they absorb it? Can you help me cut in strips in order to get at the small droplets of water used ?

There is no bloating or swelling associated with filter paper, but it's more absorbent than normal You might find it useful or not depending on your needs. It would be helpful if you could give me more details. You might want to buy the smallest size of grade 4 (fast) and try it out.
