2） Product Overview

Welded PTFE syringe filters are high-performance microporous filters for liquid separation, filtration and purification in lab and industrial scenarios.
Constructed from polytetrafluoroethylene (PTFE), the membrane delivers superior chemical inertness and tolerates all kinds of corrosive solvents and reagents, fitting diverse analytical testing workflows.
 

3） Key Features

  • Ultra-wide chemical compatibility for both aqueous and organic liquids; low protein adsorption
  • Hydrophobic PTFE membrane features excellent temperature resistance
  • Compatible with solvents, gases, strong acids and strong alkalis
  • Two standard pore sizes: 0.22 μm & 0.45 μm
  • Four outer diameter options: 4 mm, 13 mm, 25 mm, 30 mm
  • Custom packaging service available

4） Applications

  • Industrial chromatographic sample preparation
  • Filtration of aqueous solutions, organic solvents and chemical reagents
  • Eliminate particulate impurities, improve signal-to-noise ratio and stabilize flat chromatographic baselines
  • Degas and clarify liquid samples
  • Remove protein precipitates
  • Filtration of strong acid and strong alkaline solvents
