Pura Disc 13mm GF/A GMF Syringe Filters, 1.6um, 500 Pk
Whatman SKU: 6806-1316

Whatman Puradisc Glass Fiber (GF) Syringe Filters, 1.6 µm, 13 mm, 500/Pk - 6806-1316

Whatman's filtration expertise, refined across a century-plus of disciplined manufacturing, has made its name synonymous with laboratory-grade quality worldwide. Syringe filters replace the separate holder and vacuum apparatus of bulk filtration with a single disposable unit, eliminating cleaning between samples. Naturally hydrophilic glass fiber wets rapidly with aqueous samples while holding structural integrity through conditioning and stays biologically inert across diverse chemistries. The polypropylene housing holds its seal true run after run while keeping the sample chemically unaltered across the pass and sustains efficient flow on viscous samples. 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

• Reduces bioburden and particulate load ahead of sterilizing-grade filtration
• Extends filterable sample volume three to seven times versus unprotected media
• Biologically inert borosilicate fiber with broad chemical compatibility
• Surface silanol groups attract water molecules for immediate aqueous wetting
• Autoclave steam sterilization at 121°C leaves structural integrity intact

Housing Specifications

• Translucent housing wall allows visual confirmation of sample flow during filtration
• Minimal ionic background from the polypropylene housing supports ion chromatography and trace-metal ICP-MS sample preparation.
• Inert polyolefin wall contributes minimal sample adsorption to the filtrate
• Resists stress cracking from aqueous salt and buffer solutions

A clean particulate separation keeps your aqueous sample preparation dependable. Consistent aqueous clarification clears particulates without slowing your bench routine from the first sample of the day through the last. Ask about a quality certificate, lot documentation, or a blanket-order quote for your filtration order at any time.

• Wastewater Effluent Prep - Glass fiber removes suspended solids from industrial effluent ahead of COD, BOD, and nutrient compliance analysis.
• Water Analysis - Delivers high retention efficiency for suspended solids in water quality testing, ensuring accurate environmental reporting.
• Pathogen Detection Prep - Clears turbidity from food and water samples ahead of Salmonella and Pseudomonas enumeration, preventing membrane clogging.
• Crude Oil Prep - Glass fiber removes wax and asphaltene particulates from crude oil samples ahead of elemental and composition analysis.
• Tissue Culture - Clarifies tissue homogenates and cell lysates with ease, protecting finer downstream membranes from early blockage.
• Bioanalytical Prep - Clears precipitated plasma and serum proteins ahead of LC-MS/MS assay, protecting columns and autosampler needles.
