Review: good product - came quickly and my fault i got the wrong size Review: Absolutely perfect for the price - I am not filtering anything that would require the same performance/features as say a medical counterpoint, but I can attest to the fact that this filters indeed work. I've run them singularly and in pairs through a Buchner funnel with a vacuum pump (really just a relabeled aquarium pump lol) with great success. I achieved my desired results which was the removal of fine particulates from Everclear. Be forewarned, even though StonyLab produces these filters and supposedly their Buchner funnels (mine has a stamp indicating the mm of the funnel directly above a sticker that says 'StonyLab 100mm' that is laughably crooked) these 94mm are just slightly too large to rest flat in their 100mm Buchner funnel. TL;DR - They do the job at the perfect price point. ## Features - Filter paper diameter: 94mm - Coarse cellulose filter papers remove particles > 20 µm - Filtration Speed: 35 - 70 sec - Ash content: ≤0.01% - Compatible with StonyLab Porcelain Buchner Funnel ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 4.4 out of 5 stars 401 Reviews | ## Product Details - **Color:** 94mm Diameter - **Brand:** stonylab - **Material:** Coarse cellulose - **Sheet Size:** 94mm Diameter - **Recommended Uses For Product:** Laboratory ## Images ![StonyLab Quantitative Filter Paper Circles, 94mm Diameter Cellulose Filter Paper with 20 Micron Particle Retention Medium Filtration Speed, Pack of 100 - Image 1](https://m.media-amazon.com/images/I/51OJA1dy1XL.jpg) ![StonyLab Quantitative Filter Paper Circles, 94mm Diameter Cellulose Filter Paper with 20 Micron Particle Retention Medium Filtration Speed, Pack of 100 - Image 2](https://m.media-amazon.com/images/I/51DbclpFFuL.jpg) ![StonyLab Quantitative Filter Paper Circles, 94mm Diameter Cellulose Filter Paper with 20 Micron Particle Retention Medium Filtration Speed, Pack of 100 - Image 3](https://m.media-amazon.com/images/I/51Kfd38jYhL.jpg) ![StonyLab Quantitative Filter Paper Circles, 94mm Diameter Cellulose Filter Paper with 20 Micron Particle Retention Medium Filtration Speed, Pack of 100 - Image 4](https://m.media-amazon.com/images/I/61RoSbf9kZL.jpg) ![StonyLab Quantitative Filter Paper Circles, 94mm Diameter Cellulose Filter Paper with 20 Micron Particle Retention Medium Filtration Speed, Pack of 100 - Image 5](https://m.media-amazon.com/images/I/41Ok6xbACzL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ good product *by G***Y on November 29, 2024* came quickly and my fault i got the wrong size ### ⭐⭐⭐⭐⭐ Absolutely perfect for the price *by B***N on January 9, 2021* I am not filtering anything that would require the same performance/features as say a medical counterpoint, but I can attest to the fact that this filters indeed work.
