STF PTFE syringe filters

Full description
CHM® STF syringe filters are indicated to clean small volume samples for HPLC or GC analysis, where higher chemical resistance is required than offered by CHM® SRC (Regenerated cellulose).
They are supplied in two pore sizes, 0.2 and 0.45 µm, and in three diameters 4, 13 and 25 mm.

The choice of diameter depends on the volume to be filtered:

vol. <1 ml - Ø 4 mm
vol. <5 ml - Ø 13 mm
vol. <100 ml - Ø 25 mm

Features:
· Hydrophobic
· High chemical resistance to most solvents and acids
· Up to 100 ml sample
· Autoclaved

Applications:
· Filtration of strong acids and aggressive solutions
· Cleaning of small volume samples for HPLC or GC application which require greater chemical resistance than regenerated cellulose syringe filters.
· Venting applications
· Degassing solvents
· Phase separation
