GD/X 13mm Syringe Filter, PTFE Filteration Medium, 0.45um (1500 pcs)
Whatman SKU: 6875-1304

Whatman GD/X PTFE Syringe Filters, 0.45 µm, 13 mm, 1500/Pk - 6875-1304

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. Because each syringe filter is dedicated to one sample, a failed or contaminated filtration never delays the next analyst's run waiting on a shared holder. PTFE filters aggressive organic solvents without swelling or breakdown while suiting gas, vent, and solvent-stream filtration and clarifies solvent streams at the rated pore size. The polypropylene housing routes flow to minimize backpressure in service while sustaining structural integrity through elevated-temperature filtration operations and presses snugly against the membrane during the pass. For routine sample preparation across many methods, each analytical run starts with a consistent, particle-free sample without added hardware or a cleaning step.

Membrane Characteristics

• Inert composition offers no nutrient source for microbial growth
• Hydrofluoric acid resistance holds even in fully acid-digested samples
• High porosity minimizes hold-up volume for small sample volumes
• Non-fibrous, fully synthetic structure sheds no fibers into filtrate
• Stable across a wide operating temperature range for demanding methods

Housing Characteristics

• Withstands standard 121°C steam autoclave cycles without softening or structural distortion
• Burst pressure rating provides a wide safety margin above the rated maximum operating pressure.
• Minimal extractable release from the housing supports sensitive analytical work downstream
• Rigid polypropylene body maintains its geometry through routine filtration pressure

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 so your filter holds its integrity through the run.
