Whatman Disc Filters Vacu-Guard 60 mm Pack of 10 Filters

Whatman VACU-GUARD 60 mm In-Line Vacuum Protection Disc Filters (6722-5001) – Pack of 10

The Whatman 6722-5001 (by Cytiva) is a commercial-grade, in-line disc filter engineered to protect laboratory vacuum pump systems from liquid intrusion, volatile solvent vapors, and hazardous aqueous aerosols. Utilizing a high-efficiency hydrophobic polytetrafluoroethylene (PTFE) membrane housed in a robust polypropylene shell, this 60 mm diameter filter confines and isolates trace contaminants. Provided in a pack of 10, it acts as a reliable inline biosafety and mechanical barrier that preserves pump oil integrity and prevents dangerous cross-contamination within active facility exhaust lines.

Technical Performance & Design

• Hydrophobic PTFE Barrier Membrane: Outfitted with a high-purity, naturally hydrophobic 0.45 µm PTFE matrix that effectively repels aqueous solutions up to 0.9 bar (14 psi) while permitting unrestricted air flow profiles.
• 99.99% Airborne Particulate Retention: Engineered to deliver exceptional gas scrubbing performance, capturing 99.99% of airborne particles greater than 0.1 µm to intercept infectious micro-particles or radioactive dust arrays.
• Stepped Hose Barb Connections: Fabricated with heavy-duty, integrated 3/8-inch to 1/2-inch (10 mm to 12 mm) stepped hose barb inlet and outlet ports, facilitating quick, leak-free slip fits with standard vacuum tubing.
• Chemically Inert Polypropylene Housing: The entire 60 mm diameter protective capsule is molded from premium virgin polypropylene, resisting structural degradation when exposed to aggressive organic solvents, acid vapors, and routine chemical clean-downs.

Key Benefits & Applications

• Vacuum Pump Fluid Protection: Positioned directly upstream from mechanical rotary vane or dry diaphragm pumps to intercept water aerosols and condensation before they mix with and degrade internal pump lubricants.
• Biosafety Exhaust Containment: Crucial for vacuum lines hooked up to aspiration flasks, cell culture hoods, and liquid traps, preventing dangerous bio-aerosols from venting out into the open laboratory environment.
• Evaporation Transfer Loop Safeguards: Ideal for monitoring gaseous chemical transfers, moisture-sensitive analytical systems, and vacuum drying chambers where moisture back-migration could ruin sensitive compound baselines.
• Rapid In-Line Deployment: Symmetrical housing layout permits easy horizontal splicing into existing flexible lines without requiring specialized backing nuts, brackets, or tools.
