Protects valves and pump components from damage due to liquids
  • Hydrophobic PTFE membrane.
  • Allows air and gases to pass through freely while blocking aqueous solutions and aerosol contaminants.
  • Highly effective retention of bacteria with minimal restriction of pump performance.
  • Meets OSHA regulations for protection of vacuum lines (29 CFR Part 1910.1030) for bloodborne pathogens.
  • 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.
