PTFE (Teflon) Membrane Filter, Hydrophobic, White, Non-sterile, Plain Discs, 5,0 μm, 90 mm, 25 pcs/pack
Article no.: PT50090BL
The unique properties of PTFE — strong, acid/base/solvent/temperature-resistant, hydrophobic, low background, and low tare mass — make it ideal for gravimetric, chemical, and/or microscopic analysis of particulates.
Depending on your application and need, a PTFE membrane filter from our selection will provide the quality and results you need.
It must be pre-wetted with an organic solvent, such as ethanol, methanol or isopropanol, before filtration of aqueous samples.
Standard Features
Made entirely of PTFE (polytetrafluorethylene), reinforced by Polypropylene net
Permanently hydrophobic
Allowing passage of air even at low differential pressure
Resistant to almost all chemicals, very strong acids, cryoliquids, alkalis, aggressive organic solvents
Adsorption 8 μg/cm² for ɣ-globulin (pore size 0,2 μm)
Extractables with water not detected
Sterilisation: by autoclaving (at 121ºC or 134ºC) or by ethylene oxide
Temperature-resistant up to 145ºC
Applications
+ Filtering chemically aggressive samples
+ Clarifying corrosive substances, strong acids and alkalis (0,45 μm)
+ Clarification of samples and mobile phases of HPLC (0,45 μm)
