Inert Teflon Aperture (TF Series)
Overview
TF Series inert (PTFE) apertures: chemically inert, contamination-free, high temperature resistance (melting point 328°C), resists strong acids, ø9.5mm disc, holes 10-1000µm.Description
【Product Overview】
The TF Series inert (Teflon/PTFE) apertures are manufactured from polytetrafluoroethylene, chemically inert and contamination-free, withstand high temperatures (melting point 328°C, max service temperature 260°C). Ideal for demanding environments requiring high cleanliness and corrosion resistance. ø9.5mm standard disc, hole sizes 10-1000µm.
【Key Features】
(1) PTFE is chemically inert, no chemical reactions, contamination-free;
(2) High temperature resistance: melting point 328°C, max service 260°C;
(3) Resists strong acids and aggressive solutions;
(4) ø9.5mm standard disc, thickness 0.254-0.381mm;
(5) Hole sizes 10-1000µm, optional MT-25 / MT-16 mounts.
【Typical Applications】
Filtration of strong acids and aggressive solutions, venting, phase separations, aerosol samplings, environmental/water/oil/chemical/medical/food processing.
