StonyLab Qualitative Filter Paper Circles, 46mm Diameter Cellulose Filter Paper with 20 Micron Particle Retention Medium Filtration Speed, Pack of 100

Brought as additional filtration in a 9 cup (Bialetti) moka pot, fit perfectly did a good job. Initially thought they were quite thick but they just need separating

It’s a filter and it’s made of paper

Saves me a ton of time and hassle having to cut filters for my Closed Loop extractor. The 75mm is perfect for tri clamp sanitary 3” spools to fit in the gasket without overlapping the Center ring of the gasket, allowing the filter to be clamped in the gasket so it doesn’t move during extraction or have product pass by without being filtered. All in all a great purchase, high quality, low box design to save you a few extra dollars. Even the company name fits in with BHO extraction almost haha Stony lab! Keep up the great work! If you do BHO as well then this is the stuff to get, the quantitive contains Ash and it will contaminate the product return.

Ottimi filtri perfetti per imbuti da laboratorio , poi Stonylab ... non si sbaglia . Grazie.

Parfait

Filters worked very well. Filtered precipitated gold powder, it was very fine. Solution went in a brownish mud color, came out clear in the beaker after passing through the filter. It fit well, was true to its description.

All’s good
