PTFE Polytetrafluorethylene Membrane Filter
PTFE is one of the most heat-stable plastic materials. At a constant temperature of 250°, maintaining initial characteristics without showing any breakdown. This is the type of membrane most widely used in the preparation of samples for HPLC analysis.
Manufactured using a (PTFE) DORSAN® Polytetrafluorethylene polymer, it obtains a chemically stable and inert microporous film. Manufactured on a polyester spun bound calendered base which provides it with high resistance to pressure and breakage. This type of membrane has a wide range of applications, both in the natural hydrophobic version as well as the treated hydrophilic version. Widely used due to their great resistance to the majority of acid, alkaline and solvent products.
FEATURES
Hydrophobic or hydrophilic versions.
Resistant to the majority of acids and alkalines.
Chemically stable and inert.
Hard wearing during handling.
Possibility of sterilisation in auto key.
APPLICATIONS
Solvent clarification
HPLC samples preparation
Corrosive products filtration
Ventilation
Microelectronics
