Whatman Polycap filter for aggressive solvents
Filtration of organic solvents and aggressive solutions requires a durable membrane for filtration without sample contamination.
Autoclavable Polycap TF capsule filters feature PTFE membranes with high chemical resistance. Common applications include venting, in-line filtration to sterilize* and remove particles from air/gas/liquid streams, filtration to ensure clean inert gases in vial filling lines, and isolation of exhaust from fermenters.
Polycap TF filters support use in the electronics, pharmaceutical, and biopharmaceutical industries, because they are photoresistant and can be used to vent and perform in-line filtration for production systems in biological environments.
Looking for a filter paper, membrane filter, or syringe filter? Let Cytiva help you find the optimal filter for your needs to ensure reliable analysis.
*Refers to sterilization by filtration for small sample use which is an industry term for filters of pore size 0.2 um or smaller as referenced in guidance such as EPA Guidance for Industry Sterile Drug Products Produced by Aseptic Processing — Current Good Manufacturing Practice Section IX, Part B (September 2004).
