Whatman GD/X PTFE Syringe Filters, 0.2 µm, 13 mm, 1500/Pk - 6875-1302
Whatman ties GD/X prefiltration performance to one closely held fiber-grade standard applied at every production run, keeping results repeatable from one manufacturing lot to the next. A syringe filter with a hydrophobic vent-rated membrane keeps gas and vent lines free of microbial ingress. Hydrophobic PTFE delivers sterilizing-grade gas and vent filtration at the rated pore size while suiting solvent filtration where other membranes fail and repels water while passing gases and solvents freely. Polypropylene construction resists chemical degradation from routine sample matrices and holds its seal true run after run. No separate sterilization cycle is needed when the gas path already runs through a validated sterile-grade membrane.
Membrane Characteristics
- High membrane porosity, 70 to 80 percent void volume, delivers high flow at low pressure
- Solvent tolerance includes full-strength tetrahydrofuran and chlorinated solvents such as dichloromethane
- Stable across a wide operating temperature range for demanding methods
- Membrane integrity holds across repeated autoclave sterilization cycles at 121°C to 134°C
- Ionic and metallic extractable levels stay very low
Housing Characteristics
- Thermal-bonded construction keeps adhesives out of the fluid path
- The seal formed against the membrane blocks bypass at rated operating pressure
- Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
- Medical-grade polypropylene with broad chemical compatibility
Removing particulates from organic solvents and reagents before they move downstream keeps contamination out of your results. Reliable solvent prefiltration clears particulates from your organic samples from reaction mixtures and crude extracts through further processing. Ask about a quality certificate, lot documentation, or a blanket-order quote for your filtration order at any time.
