Filter Paper 7 cm Lab Qualitative Filter Paper for Chemistry, Standard Qualitative Grade 2-Slow Flow 70mm(100 Discs)

wonderful results using these for filtration, my meth came out cherry chingón

Exactly what I needed for my Krups since it was discontinued. Found some on ebay without box for much more. These are fairly priced and work perfect.

The filter works very well and requires a significant amount of time for materials to percolate through. The connect version are probably much better for filtering out material but their cost difference is substantial. Used to filter out motor oil to inspect for engine damage.

Slow flow filter paper performs just as well as Whatman filter paper but is much cheaper.

Sadly I had to return these cause a issue with another item on Amazon was miss marked.

They get the job done. I'll buy more when I run out.

Filter paper packed in unlabeled plastic bags with no identification nor batch number. Not comfortable using these in my lab.

These work great and fit perfectly into my funnel. High quality and great price!
