PTFE is a thermoplastic polymer, which is a white solid at room temperature, with a density of about 2.2 g/cm3. According to DuPont, its melting point is 327 °C (621 °F), but its properties degrade above 260 °C (500 °F). PTFE gains its properties from the aggregate effect of carbon-fluorine bonds, as do all fluorocarbons.

Syringe Filter: PTFE. A syringe filter generally consists of a plastic housing with a membrane which serves as a filter. The fluid to be purified may be cleaned by drawing it up the syringe through the filter. We offer three filter diameters: 15mm, 25mm and 30mm with membranes made of the following materials: PTFE .
Ideal prefilter in samples for HPLC. PTFE Polytetrafluorethylene Syringe Filters. T Series. DORSAN® syringe filters, manufactured with naturally hydrophobic Polytetrafluorethylene membranes (PTFE). This is the type of membrane most widely used in the preparation of samples for HPLC analysis. PTFE is widely used due to its great resistance to the majority of acid, alkaline and solvent products.
Mar 22, 2016 · Following vigorous vortexing (10 s) and sonication (40 kHz, 20 min in a water bath maintained at 20 °C), samples were centrifuged at 20,000 g for 10 min and the supernatants transferred to clean tubes. Supernatants were then filtered through 0.2 μm PTFE syringe filters and transferred to HPLC vials.
Tisch Scientific PTFE Syringe filters are perfect for their ability to resist acids and other harsh chemicals that break down other membrane filters. Our syringe filter housings are constructed of durable and chemical resistant polypropylene. No adhesives are used in the construction.
