Quantative and Qualitive Filter Paper
Lab filter paper carries multiple sizes, counts, grades, and formats typically available as pre-cut circles. Filter papers are also sold as sheets or rolls, which can be cut to size where needed and adjusted to your ideal size.
Options include Buchner funnel filter paper, ashless filter paper, and fiberglass filter paper all manufactured from natural cellulose, glass fiber paper, quartz fibers, and nylon.
The adaptability of filter paper means they offer compatibility with various laboratory equipment. Options available include conical funnels and other instruments that can assist with filtering solids from aqueous solutions.
Qualitative and quantitative filter papers are excellent for clarifying and purifying samples for analysis. They are graded numerically depending on pore size, indicating flow rate, retention, thickness, and burst strength.
