Whatman 6722-5000 VACU-GUARD, 0.2 micrometer PTFE, 50mm Disc, 10/pk (PN:6722-5000)

These Vacu-Guard discs are in-line vacuum protection filters designed to trap aerosols, particulates, solvent vapors, and other contaminants in vacuum systems, helping to protect vacuum pumps and the laboratory environment from exposure and damage.

The hydrophobic PTFE membrane has a pore size of approximately 0.2 µm, which enables it to retain fine airborne particles while allowing air to pass through. This membrane helps block liquid aerosols and protects downstream equipment in vacuum applications.

Yes — by capturing particulates, aerosols, and fluid contaminants before they reach the pump, the Vacu-Guard discs help reduce contamination and maintenance issues, which can prolong the life and efficiency of vacuum pumps.

The 50 mm discs are designed for in-line use with stepped barb connections compatible with common vacuum tubing (e.g., 10–12 mm inner diameter hose), making them easy to integrate into typical vacuum lines.

Yes — because these discs collect particulates and aerosols during use, they should be replaced periodically based on the level of contamination and system demands to maintain effective protection of vacuum equipment.
