Db11 FunChem Quantitative Filter Paper Circles | 94mm Diameter, 20 Micron, Medium Speed | Pack Of 100 | Lab Filtration Paper

For lab work, science projects, or any filtration task that needs consistent results, these db11 filter papers are a reliable choice.

You get 100 circles, each 94mm in diameter, made from coarse cellulose with a 20-micron pore size – great for removing particles larger than 20 µm.

They offer a medium filtration speed (around 35-70 seconds) and have a low ash content (≤0.01%), which is important for accurate quantitative analysis.

They fit nicely into standard 100mm Buchner funnels, but you can also use them in funnels for general gravity filtering.

Whether you're filtering chemical solutions, prepping samples, teaching a lab class, or doing DIY science at home, these papers get the job done without clogging too fast.

The pack of 100 means you've got plenty on hand for multiple experiments.

Just a solid, no-fuss filter paper that does what it's supposed to do.

Handle with clean tools to avoid contamination, and you're good to go.
