Pura Disc 13mm GF/A GMF Syringe Filters, 1.6um, 100/Pk
Whatman SKU: 6820-1316

Whatman Puradisc Glass Fiber (GF) Syringe Filters, 1.6 µm, 13 mm, 100/Pk - 6820-1316

Whatman verifies performance ratings at the lot level using process controls that stay uniform across its entire filtration lineup. Syringe filters replace the separate holder and vacuum apparatus of bulk filtration with a single disposable unit, eliminating cleaning between samples. The glass microfiber matrix accepts water-based samples on contact while sustaining high dirt-loading capacity and resists chemical attack across diverse solvents. Polypropylene construction maintains a low-dead-volume internal flow path and keeps sample purity intact through the filtration 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.

Technical Specifications

• Surface silanol groups attract water molecules for immediate aqueous wetting
• Autoclave steam sterilization at 121°C leaves structural integrity intact
• Reduces bioburden and particulate load ahead of sterilizing-grade filtration
• Inorganic construction suits demanding sample-preparation chemistries
• Biologically inert borosilicate fiber with broad chemical compatibility

Housing Specifications

• Rigid polypropylene body maintains its geometry through routine filtration pressure
• Resists stress cracking from aqueous salt and buffer solutions
• Standardized luer connection geometry provides secure engagement with standard syringe tips
• Housing tolerates elevated-temperature aqueous and solvent sample filtration up to about 80°C without softening.

Filtering buffers, reagents, and aqueous samples keeps your preparation moving and consistent. Consistent aqueous clarification clears particulates without slowing your bench routine from the first sample of the day through the last.
