Vacushield™ Vent Device

Protects Valves and Pump Components
from Damage Due to Liquids

• Incorporates a hydrophobic PTFE membrane
• Allows air and gases to pass through freely while blocking aqueous solutions and aerosol contaminants
• Offers highly effective retention of bacteria with minimal restriction of pump performance

• Use between a pump and receiving vessel to protect valves and pump components from damage by aqueous solutions
• Protects laboratory personnel from potential biohazards, airborne contaminants, and aerosolized oil
