Filter Discs

Filtration discs can be used for quick, yet efficient fluid and gas purification laboratory procedures. These discs can also be used for clarification of acids, bases, and solvents. Filtration discs combine the inertness of PTFE with the resealability of silicone. Available in a range of sizes to fit vials of different volumes in milliliters, the discs can be made of porous borosilicate glass or paper.
