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: 125mm - Coarse cellulose filter papers remove particles > 20 µm - Filtration Speed: 35 – 70 sec - Ash content: ≤0.01% ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B08NSSYTBD | | Best Sellers Rank | #57,503 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #4 in Quantitative Lab Filter Paper | | Date First Available | April 25, 2019 | | Item Weight | 3.99 ounces | | Item model number | SL000243 | | Manufacturer | StonyLab Scientific | | Product Dimensions | 4.92 x 4.92 x 0.39 inches | ## Product Details - **Color:** 125mm Diameter - **Brand:** stonylab - **Material:** Cellulose - **Sheet Size:** 125mm - **Paper Finish:** Uncoated ## Images ![StonyLab Quantitative Filter Paper Circles, 125mm Diameter Cellulose Filter Paper with 20 Micron Particle Retention Medium Filtration Speed, Pack of 100 (125mm Diameter) - Image 1](https://m.media-amazon.com/images/I/51VE25FLpvL.jpg) ## 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.
