Application

  • Sterile filtration
  • Buffer filtration
  • Tissue culture media filtration
  • Sample filtration for PFAS analytical testing (LC-MS)

Other Notes

Directions for Use

  • Organism Retention: Microorganism
  • Mode of Action: Filtration (size exclusion)
  • Application: General laboratory filtration
  • Intended Use: Retention or removal of biological contaminants
  • Instructions for Use: Sterilizing filtration of a liquid through a membrane with a 0.2 μm (or smaller) pore size effectively removes biological contaminants, including bacteria, mold and yeast. For the selective retention of larger biological contaminents, liquid filtration through membranes with 0.45 μm (or larger) pore sizes may be used to trap and support microorganism growth for subsequent culture and analysis
  • Storage Statement: Store in dry location
  • Disposal Statement: Dispose of in accordance with applicable federal, state and local regulations.
