Whatman filterpapier, niveau 5 (100 stuks), 9.0cm, 100

Found it very good for seperating materials from liquids.

If you're a fellow Canadian who can legally grow their own medicinal herbs these filter papers are perfect for removing the small impurities that a soak in alcohol produces.Until you see for yourself how much a coffee filter leaves behind, you don't realize you need these.These are the "slower" filter papers that remove the bulk of the contaminants. If you plan on using dry ice to "winterize" your extraction, you can benefit from also buying the "medium" speed 6 micron filter papers to use for that step (which you should do after the initial 2.5 micron filtration as a cleaner frozen extraction will pass through the medium speed filter much quicker and will be less likely to 'melt' the plant fats you're trying to separate)

Muy buen producto.

Muy gruesos no me gustaron, porque no me es útil para lo que quería aunque para otras cosas sería una buena opción por el precio.

The Whatman brand is a consistent filter medium for laboratory use.
