stonylab Quantitative Filter Paper, 100 Pack Slow Flow Rate Cellulose Filter Paper Circles with 10 Micron Particle Retention, 74 mm Diameter

Works exceptionally well.

Decent quality papers, but I got a lot of “sucked through” holes which is bad, and contaminates whatever you’re filtering. THEN I LEARNED to wet them with distilled water and get the suction seated before adding acid. When I did this, they worked fine! They even stood up to 20-30 minutes of suction without tearing! Good quality papers, just dampen first!

I use these to filter gold particles from ultrasonic solutions.

I guess they do what they are supposed to do, but I've heard Milk filters are way better and apparently way cheaper as well.

I was looking for very fine filter paper for use with vacuum filtration. This was the best I could find.

Det är som förväntad,funkar som den ska .Många skriver att den släpper inte genom trögare vätskor men det gör bara väääldigt långsamt ,20 ml propylenglyckol tar ca.48 timmar.

Super Material und ist genauso wie beschrieben!!!! Top.......

I'd have giving it 5 star as its the best filters on the market compared to the price however I have recived a damaged package

Filters are good.

Prodotto costoso ma che soddisfa appieno la qualità.
