GD/X 13mm Syringe Filter, PTFE Filteration Medium, 0.2um (150 pcs)
Whatman SKU: 6874-1302

Whatman GD/X PTFE Syringe Filters, 0.2 µm, 13 mm, 150/Pk - 6874-1302

Whatman places a fibrous glass mat before the final membrane in every GD/X device, clearing a turbid sample in one pass through the same housing. Gas and vent service calls for a hydrophobic syringe filter rated to the same sterilizing-grade pore size as its liquid counterpart. Hydrophobic PTFE delivers sterilizing-grade gas and vent filtration at the rated pore size while suiting solvent filtration where other membranes fail and suits gas, vent, and solvent-stream filtration. Low-extractable polypropylene keeps sample purity intact through the filtration pass and sustains its dimensional form through high-temperature filtration workflows. Downstream equipment and work areas stay protected from airborne bacterial contamination once the vent path runs through the membrane.

Membrane Characteristics

• Hydrofluoric acid resistance holds even in fully acid-digested samples
• Solvent tolerance includes full-strength tetrahydrofuran and chlorinated solvents such as dichloromethane
• Non-wetting pore surface blocks liquid water while passing water vapor freely
• Inert composition offers no nutrient source for microbial growth
• Minimal moisture absorption pairs with a low tare mass

Housing Characteristics

• Polypropylene density near 0.90 g/cm3 keeps housing weight low relative to denser engineering plastics
• Low moisture absorption keeps the housing dimensionally stable through humid storage and shipping
• PP housing rated to 121°C holds its geometry through high-temperature sample preparation and processing.
• Minimal intrinsic autofluorescence from the polypropylene housing supports background-sensitive fluorescence-based assay work downstream.

Filtering aggressive solvents and reagents through a filter that holds up to the chemistry keeps your sample prep reliable. Solvent-stream filtration handles the solvents and reagents your methods rely on across the organic solvents and harsh reagents your methods use.

Hydrophobic

• Air Monitoring - Ensures precise capture of airborne particulates for environmental analysis in demanding atmospheric monitoring conditions.
• Chemical Synthesis - Resists aggressive organic solvents and corrosive acids for compatibility with harsh synthetic reaction mixtures.
• Cryogenic Fluids - Delivers consistent performance across extreme temperature ranges, filtering cryogenic liquids with dependable, reliable results.
• Pump Protection - Acts as a hydrophobic barrier that protects vacuum pumps from corrosive moisture and particulate damage.
• Spirits Congener Analysis - Clarifies distilled spirits samples ahead of GC analysis, protecting columns from residue during congener profiling.
• Dye and Pigment Analysis - Clarifies dye solutions in DMF, NMP, and other aggressive organics ahead of spectrophotometric color strength testing.
