Micron Filter Membranes
|Durapore® Membrane Filters
Material: PVDF (Polyvinylidene fluoride)
Features: Low Protein Binding
Applications: Particulate removal. Compatible with aqueous solutions and some organic solvents.
Material: PES (polyethersulfone)
Features: High throughput and low protein binding
Applications: Clarification and sterilization of fluids, mainly aqueous. Ideal for hard-to-filter solutions.
Material: MCE (mixed cellulose esters)
Features: General/Buffer filtration and particle monitoring
Applications: Air monitoring and contamination analysis for fuels and hydraulic fluids. Clarification and sterilization of fluids/buffers.
Material: track-etched polycarbonate
Features: Smooth, glass-like surface
Applications: Environmental/Air analysis. Use with aqueous solutions and some organic solvents.
|Fluoropore™, Mitex™, Omnipore™, and LCR HPLC-Certified Membrane Filters
Material: PTFE (polytetrafluoroethylene)
Features: High flow rate and broad chemical compatibility
Applications: Clarification of acids, bases, solvents, and analysis of hydraulic fluids. Broad chemical compatibility.
|Microfiltration Membrane Support Materials
Material: Cellulose-based pads; spacers are woven from Dacron filaments
Applications: Cellulose pads reinforce filters in Merck’s monitors for contamination analysis. Spacers separate membranes to prevent “blinding” of membranes during 2-stage serial filtration.
